Pest Control for New Homeowners: Move-In Inspection Guide

You get one clean slate with a new house. Paint dries once, boxes get emptied once, and the first week you sleep there sets the tone for how the place will run. The same goes for pests. A careful inspection during move-in finds small issues while they are still cheap and quick to fix. Leave it to chance, and you could be budgeting for subfloor repairs, wiring damage, or a recurring ant trail that never seems to end.

I’ve walked more than a hundred families through first-week inspections, from mid-century homes with tucked-away crawlspaces to brand-new construction that still smelled like sawn pine. The patterns repeat. Most infestations start with moisture, clutter, or a gap that looks too small to matter. Most can be intercepted with simple changes made early. The trick is stepping through the house in a deliberate order, understanding which signs are meaningful and which are just part of a home’s normal life.

Why the timing matters

A house behaves differently when it is empty. You have sightlines you will never get again. Baseboards are visible. Behind-appliance gaps are reachable before you plug anything in. The quiet helps too. In the evening you can hear rodent movement or a wasp burrowing into fascia that would disappear under everyday noise. If you handle basic pest control groundwork now, you avoid disrupting your future kitchen or nursery to chase problems later.

There is also the seasonal clock. Termites swarm in spring in many regions, mice push indoors when night temperatures dip, and late summer brings yellowjackets building in eaves and ground voids. Your move date sets which risks are front and center. The inspection route here is built to adapt to season and region.

A fast orientation to common household pests

Every region has its regulars. In the Southeast, subterranean termites and American roaches are the headliners. In the Northeast and Midwest, mice and carpenter ants have top billing. Desert homes fight pack rats and scorpions. Coastal houses deal with moisture ants and roof rats. Construction type matters as well. Slab-on-grade invites slab edge termites and ant infiltration along hairline cracks. Pier and beam platforms bring crawlspace rodents and moisture-driven pests like springtails.

What you are looking for is evidence rather than sightings. A single ant in a kitchen could be a scout from a colony ten yards outside. One mouse dropping tells you there was at least brief activity, but the shape, color, and location say whether it is historic or current. Think like an insurer and ask: where is the risk concentrated, how current is it, and what is the likely path of travel.

The exterior sets the stage

Start outside. The building envelope decides which pests even get a chance. I begin at the driveway and walk the perimeter at least twice, once looking at eye level and again crouched low.

In siding, hairline gaps around utility penetrations often matter more than dramatic cracks. A quarter inch gap is plenty for mice and American roaches. For context, an adult mouse can compress to the size of a dime. Caulk cures many sins, but only if the substrate is dry and clean. I keep a notepad or phone list of every gap, then prioritize by size and proximity to food rooms like the kitchen.

Landscaping often telegraphs pest load. Mulch mounded against siding is a termite and ant escalator. Keep it 4 to 6 inches below the bottom of the siding and pull it back so you see a bare inspection strip of foundation. If shrubs touch the house, treat them as a bridge. I advise trimming so there is a hand’s width between foliage and exterior walls. Vines on brick may look charming, but they hold moisture and hide wasp nests and mortar cracks.

Downspouts and grading deserve more attention than most buyers give. Where water pools, wood softens. Where wood softens, carpenter ants and termites gain ground. If a downspout terminates right beside the foundation, budget for a diverter to send water at least 5 feet out. Look for spongy trim at the base of columns and door frames. A screwdriver probe that sinks in more than a few millimeters signals rot that can attract pests even if you see no insects today.

Rooflines tell stories from a distance. Wavy or lifted shingles near eaves can hide wasp entry. Gaps in soffit vents, bird netting that has torn, and missing screens on gable vents all invite starlings and squirrels. Birds do not seem like a pest problem until they do. Their nests host mites and beetles, and their droppings are corrosive and messy to remove.

Finally, scan the ground. Pencil-thin mud tubes rising from soil to foundation often belong to subterranean termites. They are not always obvious. Look behind meters, AC line sets, and where bushy landscaping hides slab edges. In warm months, small conical piles of soil at slab cracks can signal ant excavation. At fence lines and sheds, burrow openings 2 to 3 inches across may indicate rats rather than harmless ground beetles. The size and shape matter. A vole hole tends to be smaller and set in turf, while a rat burrow has a worn pathway and grease marks nearby.

The quick move-in pest inspection loop

Use this short loop before furniture and appliances block your view. It trades depth for speed, so you can complete it in an afternoon, then decide where to dig deeper.

• Exterior perimeter: note gaps, wood-to-ground contact, mulch depth, grading, soffit and vent screens.
• Garage and utility rooms: inspect door sweeps, wall penetrations, and stored cardboard for droppings or webbing.
• Kitchen and laundry: open every cabinet, look for frass, droppings, water staining, and active trails.
• Attic and crawlspace or basement: check insulation disturbance, droppings, rub marks, and moisture.
• Bedrooms and living areas: baseboards, window frames, and closet corners for cast skins, fecal spotting, or live insects.

If you find nothing urgent, you still learned the home’s weak points. If you find something real, you now have a map to act.

Kitchens are truth tellers

I always start interior detail work in the kitchen because it concentrates heat, moisture, and food odor. Pull the range if possible. Few sellers clean behind it thoroughly, which means you can read the last year like a core sample. German roach activity shows as pepper-like spotting, shed skins that look like flat shells, and oothecae, the tan egg cases. One or two specks do not make a problem. A constellation behind the stove and under the sink points to a live population that will bloom once the home warms from daily cooking.

Under-sink cabinets often hide slow leaks. Touch every shutoff valve and the bottom of the P-trap with a dry paper towel. If it comes back damp, fix the leak before you store anything below. Roaches, silverfish, and ants ride both moisture and corrugated cardboard. Replace cardboard boxes with sealed plastic bins for pantry backup stock. If you see ant trails, note whether they are coming from electrical outlets or cracks at the backsplash, then bait at the points of entry rather than chasing trails with spray. Contact sprays scatter workers and make control slower.

Laundry rooms and utility closets are next because they often share the same walls and plumbing runs. Lint and warmth draw spiders and roaches, but the bigger story is the two inch dryer vent hole that was not sealed around the duct. I once found a bat in a new construction laundry room because the builder left a gap at the jamb the size of my pinky. A five dollar can of foam would have stopped it. Seal gaps with materials that match the opening. Use silicone or urethane sealant for small cracks and backer rod plus sealant for larger joints, steel wool for rodent-prone penetrations, and escutcheon plates where pipes pass through drywall for a clean, tight finish.

Bedrooms and living spaces

Most family rooms and bedrooms do not breed pests on their own. They host them. That means you are hunting for sleep sites and travel routes. Pull back drapes. Check the top corners of window frames for cobweb moth casings and spider egg sacs. If you inherited window units or wall AC sleeves, inspect the side gaps and screens. I have yet to meet a rodent that resisted the warmth behind a built-in media cabinet. Shine a flashlight along baseboards to highlight droppings. Fresh mouse droppings are black and glossy, and they smear if pressed with a cotton swab. Old ones fade to gray and powder if crushed. That simple test helps you decide whether to set traps immediately or simply close gaps and monitor.

If bed bugs are a remote concern because you bought used bedroom furniture or you are moving from a multi-unit building, do a preventive sweep. Look organic pest control at mattress seams, the underside of the box spring, the headboard back, and the screw holes on bed frames. Bed bugs leave rust-colored dots from digested blood, as well as casings the size of apple seeds. You can find early activity with interceptors placed under bed legs before you bring in bedding. Those cup-like traps catch bugs as they try to climb up at night.

Closets, especially those with attic scuttle access, deserve a good look. Rodents use scuttle edges as runways. Look for gnawing on stored items and for cedar block shredding. Moths are more of a textile issue than a whole-house pest, but a closet with a constant 60 to 70 percent humidity is a magnet for webbing clothes moths. A cheap hygrometer set on a shelf tells you whether a dehumidifier is worth running.

Attic realities

Attics tell you how the house breathes. They also tell you who has been living above you. If you can’t safely navigate the joists, take photos from the scuttle and use zoom to check a few angles. You are looking for trails matted into insulation that trace rodent routes. Rodent latrines cluster on framing near vent stacks or along the ridge line. Grease marks on rafters and at entry gaps around conduits are common where roof rats commute from trees.

Bats leave distinct guano that looks like mouse droppings but crushes into glittery fragments because of insect exoskeletons. If you find that, do not seal anything until you understand exclusion timing and local wildlife rules. Sealing bats in is both illegal in many places and a recipe for dead animals in the walls. In late summer, yellowjackets and paper wasps build in roof decking voids and at gable ends. Tap suspect areas gently and listen for humming. If you are allergic to stings, bring a partner and daylight, not bravado.

Ventilation hardware matters. Missing or torn screens on soffit and ridge vents are invitations to birds and squirrels. Improvised fixes with cloth or plastic rarely last. Use hardware cloth with quarter inch openings for rodent resistance. The difference between a quiet attic and a recurring service call is often a twenty dollar roll of proper mesh and an hour with tin snips and a staple gun.

Crawlspaces and basements

If your home has a crawlspace, you inherited a microclimate. Moisture control here sets the tone for pests upstairs. Bring knee pads, a respirator, and a good light. Before you go in, check for live electrical hazards and tell someone you are crawling in. Inside, sniff. A humid, earthy odor points to high moisture. Look at the plastic vapor barrier if present. If it is shredded, torn around piers, or missing entirely, plan on replacing or repairing it. Termites favor contact points where wood framing meets damp piers. Pencil-width mud tubes up piers or wall foundations are strong signals. Scrape a small section to see if it is active. If termites rebuild overnight, call a licensed pro for a full treatment plan.

Rodent signs include droppings on sill plates, gnawing on conduit and PEX, and runways along the perimeter. The size of droppings separates mice from rats. A mouse pellet is about the size of a grain of rice and tapers to a point. A rat pellet is larger, often 1.5 to 2 cm. Fresh ones look moist. If the crawlspace door does not seal, or vents lack screens, you will be catching and excluding forever. Fix the portals first.

Basements bring their own patterns. Efflorescence lines on block walls indicate moisture vapor passing through. While not a pest by itself, it raises humidity that supports silverfish, sowbugs, and wood-loving fungi that invite carpenter ants. Look for cardboard storage on the floor. Replace those boxes with shelving and sealed bins set a few inches off the slab to break contact with occasional seepage.

The garage test

Two elements make the garage a pest focal point: door seals and storage. Close the door and stand inside during daylight. If you see sunlight under the bottom seal, expect insects and rodents. Bottom seals harden and crack after five to eight years. Measure the track width and replace with the correct profile. Side and top weatherstripping should press lightly against the door when closed. Gaps wider than a pencil on any edge are too big. Door thresholds help on uneven slabs where no seal fits well.

Storage practices decide whether a garage becomes a roach and mouse buffet. Pet food kept in open bags is the usual culprit. Move it into lidded plastic containers. Birdseed is another. If you see granular spills in corners, clean and store the bag in a bin. I have found mouse nests in old paint cartons, shop vacs, and in the motor compartment of a spare treadmill. Assume anything soft and quiet is prime nesting material. Elevate and seal.

Evidence reading, not guesswork

People often misread signs because they want to avoid what the sign implies. A scatter of small, irregular brown pellets on a windowsill is more likely from a house gecko or lizard than from a rat. A pile of coarse, sawdust-like frass under a window frame on the second floor may point to carpenter ants, but it may also be from drywood termites in the Southwest. Both kick out frass that piles like sand. Under a hand lens, carpenter ant frass includes insect parts. Drywood termite pellets are uniform and have six concave sides. You do not need to become an entomologist. You do need to slow down, collect a sample in a zip bag, and compare with reputable images or a local extension office.

Sound travels better in a quiet, empty house. At night, sit in the kitchen with the lights off and listen for scratching in the walls or ceiling. Slow, heavy movement often suggests squirrels. Quick, skittering sounds point to mice. Intermittent ticking in the wall during a warm afternoon can be carpenter ants. I once traced that faint, rhythmic rustle to a satellite colony in a foam-insulated header that only became audible when the sun hit the west wall.

Prevention you can build in from day one

If you prefer prevention over reaction, load it into your move-in routine. Caulk every cable and plumbing penetration you can see, then photograph each one. You will forget which you sealed later. Install door sweeps on the garage service door and any exterior doors that lack them. Trim landscape back before movers roll heavy furniture into place where you can’t maneuver a ladder easily. Replace cheap window screens with heavier mesh where pets push against them. Fit gaskets to attic scuttle covers to reduce airflow that pulls attic pests’ scent and dust into living spaces.

Set monitoring rather than traps where you have no confirmed pest. Sticky monitors under sinks, behind the range, and in the pantry base kick out early warnings. One per space is adequate. Date the undersides. If you catch a German roach in a new build, loop in the builder while warranties are still active. If you find ant workers on a monitor, bait strategically at the trail. Gel baits with indoxacarb, fipronil, or similar actives, placed as dabs, work better than sprays for most sugar ants. Rotate bait types if activity persists beyond two weeks. Protein baits play in spring when colonies need amino acids for brood, sweet baits later in the season.

For rodents, set two to four snap traps along walls in the garage and attic preemptively for the first month, baited and unset for two nights to build trust, then armed. If nothing triggers after a week, remove and keep the traps labeled in a bin for future use. Avoid leaving them indefinitely. False security leads to stale bait and ignored hardware.

Moisture management is part of pest control, not an extra. Aim for indoor relative humidity in the 35 to 50 percent range. Use the bathroom fan and verify it vents outdoors, not into the attic. Run a dehumidifier in a damp basement until the hygrometer reads below 55 percent. Fix foundation drains and downspout extensions before you consider chemical treatments for moisture ants and springtails. Dry the stage and the actors stop showing up.

When to bring in a professional

Not everything needs a crew and a contract. The line is drawn by structure risk, occupant safety, and time. You can patch caulk and set ant bait. You should not trench and treat a foundation without training, nor chase a squirrel in a chimney without gear and a plan. Costs vary by region, but think in bands. An initial rodent exclusion assessment with sealing might run a few hundred to a couple thousand dollars depending on the number and size of entry points. A termite treatment on a typical 2,000 square foot house can range from low thousands for a perimeter liquid barrier to several thousand for a baiting system with multi-visit monitoring.

Here are fast signals that a call makes sense:

• Pencil-wide mud tubes on multiple foundation faces, or wing piles near door frames after a warm rain.
• Rat-sized droppings in attic or crawl, plus gnaw marks on wiring or PEX.
• Recurring German roach activity in several rooms, not just the kitchen, especially in multi-unit settings.
• Bat or squirrel presence in attic, or bird nesting in vents that serve appliances.
• Structural wood that feels spongy at sills, columns, or window bases, paired with insect frass.

A reputable company will map findings on a floor plan, explain the treatment logic, and give you prep steps that do not sound like a generic script. If you feel rushed toward an annual contract without a specific problem identified, slow down and get a second opinion.

Safety, children, and pets

New homeowners often juggle toddlers, pets, and visiting relatives while setting up the house. Safe pest control starts with storage. Keep baits and aerosols in a locked cabinet, not under the sink beside the trash. Choose tamper-resistant bait stations if you have pets. Avoid broadcast bug bombs. They do little for hidden pests and coat surfaces you do not want coated. If you use diatomaceous earth, use the right product and apply thinly. Thick coatings push pests around and create dust inhalation risks. If you use over-the-counter ant or roach baits, place them where cleaning will not wash them away in a day. Bait is a slow play. Give it a week or two to circulate through a colony before declaring defeat.

If anyone in the household has asthma, avoid space sprays and scented aerosols. Focus on exclusion and sanitation first. Vacuum with a HEPA filter where droppings were found. Wear gloves and a mask when cleaning rodent-contaminated spaces. Mist droppings with a disinfectant before disturbing to reduce airborne particles. These steps are inexpensive and protect your health just as much as your walls.

A note on new construction

People assume a fresh build equals a pest-free start. That is a nice idea, but construction sites draw rodents and roaches with food waste, job site trailers, and piles of lumber. Framers cut penetrations that sometimes never get sealed. I find daylight where a tub drain drops into the subfloor at least one out of four times. Walk your new home with blue tape and a flashlight. Ask your builder about borate treatments on framing if you are in a termite-prone zone. They are standard in some areas, rare in others, and easiest to apply before drywall.

If you have a builder’s warranty, document issues with time-stamped photos as you find them. A roach in a sticky monitor is better evidence than a story two months later. The same goes for a gap at a sill plate large enough for a pencil. Builders respond faster when you present specifics tied to standard details.

Regional sense and seasonality

Customize your plan. In the Deep South, subterranean termites are not an if but a when. Pre-treatment records matter. In the Pacific Northwest, carpenter ants and moisture are the duo to watch. In the Mountain West, pack rats and voles cut irrigation lines and chew car harnesses as readily as they raid pantries. In the Northeast, fall is rodent season indoors when first cold snaps arrive. Seal and set monitors before that date, not after. If you move in during winter and find nothing, revisit the exterior in spring when soils heave and settle, opening fresh cracks.

A simple practice helps anywhere: keep a pest notebook for the home. Record sightings by date, place, and time of day. Glue an envelope to the back for labels you pull off bait stations so you remember which actives you used. The notebook becomes your memory when seasons change and life gets busy.

Working with the house you have

Every house has quirks. A crawlspace too tight to enter safely, a steep roof you will not walk, an antique door you prefer not to replace for the sake of a perfect bottom seal. Work around those constraints. If the chimney cap is out of reach, hire an installer rather than risking a fall. If you love the ivy on the brick, budget for quarterly pruning and a regular inspection behind it. Pest control is not about making a museum. It is about reducing risk on the margins where pests exploit neglect.

One homeowner I guided had a craftsman bungalow with a porch skirt that met soil. She loved the look and hated the idea of pulling it back. We compromised. We cut a narrow inspection strip along the base, added a gravel barrier that drained well, and built a removable panel for access to check for termite tubes. Five years later, the house is still charming, and we can see what we need to see.

The payoff

A careful move-in inspection is not glamorous. You will track dirt, crouch under stairs, and find the occasional surprise you did not ask for. But the payoff is tangible. Instead of reacting to trails and scratching six months from now, you decide where pests can and cannot go. You align moisture, storage, and structure with what you want your home to be. That is pest control at its most effective level, built into the day you claim the keys.

If you keep nothing else from this guide, keep the mindset. Look for pathways, not just pests. Fix the conditions, not just the symptom. And treat your first week as the easiest chance you will ever have to make your home a place where unwanted guests do not feel welcome.
