Move-In Pest Inspection Checklist for New Homeowners

9 min read June 2025

A vacant home sitting on the market for weeks is an open invitation for mice, rats, spiders, and wood-destroying insects looking for undisturbed shelter.

Standard home inspections rarely cover pest activity in detail, and previous owners aren't always forthcoming about what they dealt with.

Below are 25 walkthrough checks across 3 zones so you can catch problems before you unpack the first box.

The window between closing day and move-in day is your single best chance to catch pest issues cleanly. Empty rooms mean no furniture blocking baseboards, no boxes masking cabinet corners, no clutter hiding droppings or damage. Every piece of evidence is visible. Every corner is reachable. You have time to address problems before they become part of your daily life.

Work through the 3 zones below (Foundation and Structure, Hidden Spaces, Kitchen and Wet Areas). Bring a strong flashlight, a flathead screwdriver for the tap test, and your phone for photos. By the end of the walkthrough you should have a clear picture of any pest activity in the home and a prioritized plan for what to handle DIY versus what needs a professional WDO inspection.

Key Takeaways

  • Inspect within 48 hours of closing, before furniture and boxes mask evidence of pest activity.
  • Hit hidden spaces first. The attic, crawl space, and wall voids are where active infestations stay invisible longest.
  • Mud tubes running vertically on a foundation wall are a reliable sign of active subterranean termite foraging.
  • Mice slip through a 1/4 inch gap. Rats need about 1/2 inch. Walk pipe penetrations, dryer vents, and the garage door seal with that math in mind.
  • A professional WDO (Wood Destroying Organism) inspection runs $75 to $150 and pays for itself the first time it catches termites, carpenter ants, or wood-boring beetles.

Why Inspect Before You Unpack

Moving into a new home is exciting, but skipping a pest check can turn a fresh start into an expensive problem. Previous owners may not have disclosed pest history, and most standard home inspections don't cover pest activity in detail. A vacant home sitting on the market for weeks or months is an open invitation for mice, spiders, and insects looking for undisturbed shelter.

An empty home is the easiest home to inspect. No furniture blocking baseboards. No boxes hiding cabinet corners. No clutter masking droppings, trails, or damage. The window between closing day and move-in day is your best opportunity to catch pest issues while they're still easy to see and affordable to address.

Move-In Pest Inspection Checklist

Work through the 3 zones below in order. Bring a strong flashlight, a flathead screwdriver for the tap test, and your phone camera to document anything suspicious. Flag what you find and revisit it with a professional if needed.

When to Get a Professional Inspection

A DIY walkthrough catches the obvious signs, but a professional WDO (Wood Destroying Organism) inspection goes deeper. WDO inspections check for termites, carpenter ants, wood-boring beetles, and fungal damage that compromise structural integrity. The inspection typically covers the full foundation perimeter, all accessible crawl spaces, attic framing, and exterior wood elements like decks, porches, and window frames.

WDO inspections run between $75 and $150 in most markets and take 60 to 90 minutes for an average home. Some states require a WDO inspection before closing, particularly in high-termite-risk regions across the Southeast, Gulf Coast, and parts of California. Even where it isn't legally required, a WDO inspection is one of the most cost-effective steps you can take as a new homeowner. Catching termite damage early can save thousands in structural repair costs.

KEY TAKEAWAY

Do Your Inspection Before You Unpack

Empty rooms are easier to inspect, and you want to address any issues before your belongings are in the way. Start with hidden spaces (attic, crawl space, basement), then work outward to the foundation perimeter and through the kitchen and wet areas.

Why Each Area Matters

Different zones attract different pests, and the signs you're looking for change room by room. Understanding what each area tells you helps you prioritize the walkthrough and communicate clearly with a pest control pro if you find something worth escalating.

Move-In Inspection by the Numbers

$2B+ EPA: annual U.S. spending to treat termites

EPA's termite guidance reports that termites cause billions in structural damage each year, and U.S. property owners spend over $2 billion annually on treatment. A pre-move-in WDO inspection is one of the cheapest ways to avoid inheriting an active termite problem.

1/4 inch CDC: gap a mouse can fit through

CDC's rodent exclusion guidance states mice can slip through an opening about the width of a pencil (1/4 inch). Before you move boxes in, walk the empty house with a flashlight and check pipe penetrations, dryer vents, weatherstripping, and the gap under the garage door, the common mouse corridors.

3 types EPA: termite species homeowners encounter

EPA lists 3 termite types that damage U.S. homes: native subterranean (the most common), drywood, and the invasive Formosan. A pre-move-in WDO inspection should cover all 3. Subterranean termites leave mud tubes along foundations, drywood colonies show up as pellet frass inside wood, and Formosan activity leaves sprawling mud carton nests.

2 Mistakes New Homeowners Make

Skipping the Attic and Crawl Space

Most move-in walkthroughs focus on the rooms you'll live in: kitchen, bathrooms, bedrooms. But the attic and crawl space are where active infestations usually hide. Rodent nests, termite mud tubes, and carpenter ant galleries rarely surface in living spaces until the problem is large. Spending 15 extra minutes with a flashlight in the attic and crawl space catches the issues that would otherwise surprise you months later.

Assuming the Home Inspection Covered It

A standard home inspection focuses on structural, electrical, and plumbing systems, not pest activity. Most inspectors note visible droppings or obvious damage but don't probe wood with a screwdriver, check mud tubes, or assess termite risk. If pest issues matter to you (and in most markets they should), schedule a WDO inspection separately. It's a small additional cost for a specialized service a general home inspector isn't trained or equipped to provide.

The Bottom Line

A move-in pest inspection is one of the highest-value hours you'll spend as a new homeowner. Empty rooms let you see what's actually happening in the home, and catching a problem in the first week is vastly cheaper than finding it a year later when damage has accumulated and access is blocked by your belongings.

Run through the 25-item checklist above zone by zone. If you find mud tubes, rodent droppings, soft or discolored wood, or any clear sign of active pest activity, schedule a professional WDO inspection before you finish unpacking. The $75 to $150 cost is trivial compared to the protection it provides, and the peace of mind that comes with knowing exactly what you just bought.

Move-In Inspection FAQs

Common questions about this guide and what to do next.

  • How soon after closing should I do a pest inspection? Toggle answer for: How soon after closing should I do a pest inspection?

    Within 48 hours of closing, before your furniture and boxes are in the way. Empty rooms are dramatically easier to inspect: no furniture blocking baseboards, no boxes masking cabinet corners, no clutter hiding droppings or damage. The window between closing day and move-in day is your single best opportunity to catch pest issues while they're still easy to see and affordable to address.

  • What is a WDO inspection and do I need one? Toggle answer for: What is a WDO inspection and do I need one?

    A WDO (Wood Destroying Organism) inspection is performed by a trained technician to check for termites, carpenter ants, wood-boring beetles, and fungal damage that can compromise structural integrity. It typically covers the foundation perimeter, crawl space, attic framing, and exterior wood like decks and window frames.

    The inspection usually takes 60 to 90 minutes. Some states require it before closing in high-termite regions; even where it's not required, it's a smart step for any new homeowner. Catching wood-destroying pests early prevents far worse structural damage later.

  • Didn't my home inspection already cover pests? Toggle answer for: Didn't my home inspection already cover pests?

    No. A standard home inspection focuses on structural, electrical, and plumbing systems. Most home inspectors note visible droppings or obvious damage but don't probe wood, assess termite risk, or check mud tubes. A WDO inspection is a separate, specialized service. If pest issues matter to you, andin most markets they should, schedule the WDO inspection on top of your home inspection, not instead of.

  • What are the highest-risk areas to check first? Toggle answer for: What are the highest-risk areas to check first?

    Attic, crawl space, and basement, in that order. These are the zones where active infestations hide because they're rarely disturbed. Check for rodent droppings and nesting material in attic insulation, termite mud tubes on foundation walls, moisture in crawl spaces, and carpenter ant frass near damp wood. Only after these are cleared should you move on to kitchens, bathrooms, and living spaces.

  • What tools do I need for a DIY move-in pest inspection? Toggle answer for: What tools do I need for a DIY move-in pest inspection?

    Just three: a flashlight, a flat-head screwdriver (for probing soft wood), and your phone camera for documenting anything suspicious. The flashlight matters most, many signs of pest activity are only visible in dim corners, under sinks, behind appliances, and along baseboards where natural light doesn't reach. The screwdriver lets you test whether wood is structurally sound. The phone documents anything you want to show a professional later.

  • What findings should trigger a professional inspection? Toggle answer for: What findings should trigger a professional inspection?

    Mud tubes on foundation walls, soft or discolored wood around windows or joists, rodent droppings in multiple locations, moisture damage in the crawl space or basement, or chewed entry holes in the roofline. Any one of these warrants a professional WDO inspection before you finish unpacking. The cost of the inspection is trivial compared to the protection it provides once problems are confirmed.

  • Should I treat preventively even if I don't find anything? Toggle answer for: Should I treat preventively even if I don't find anything?

    Preventive exterior treatment is reasonable in high-pressure areas (warm, humid climates) or for homes with minor vulnerabilities like older construction. If your move-in walkthrough is clean, a baseline inspection and perimeter treatment as you settle in is cheap insurance. If you find any active signs, treat those first and then decide about ongoing service based on what the professional recommends after assessing the property.
