Cockroach Inspection
The first step in nearly every visit, confirming what species is involved and where the activity is concentrated.

Because German cockroach and palmetto bug situations call for different approaches, confirming which one applies, and how established it is, shapes everything that follows.
What Actually Happens During a Visit
A specialist typically walks through likely harborage areas, kitchens, bathrooms, exterior entry points, looking for activity, droppings, egg cases and moisture sources, and asks about where and when you've seen activity.
What Happens After the Inspection
Based on what's found, a specialist explains a treatment approach in plain terms, along with any exclusion or sanitation recommendations, before anything begins.
Areas Typically Checked
| Area | What a specialist is looking for |
|---|---|
| Kitchen, under sink, behind fridge and stove | Droppings, egg cases, live activity, moisture |
| Bathrooms | Leaks, drain seals, cabinet dampness |
| Laundry and water heater area | Warmth plus moisture, a common harborage pairing |
| Garage | Cardboard storage, gaps under the door |
| Exterior perimeter | Mulch depth, door sweeps, weep holes, utility penetrations |
| Attic or crawlspace (when relevant) | Entry routes and outdoor species activity |
The Evidence That Tells the Story
A specialist reads the physical evidence as much as the live roaches. Fine, pepper-like droppings along cabinet hinges point to German cockroaches; larger cylindrical droppings near a garage door point to outdoor species. Shed skins and egg cases show whether breeding is happening indoors, and a musty odor in an enclosed cabinet can indicate a larger population than sightings suggest.
Location of evidence matters as much as the evidence itself. Droppings concentrated along one cabinet hinge suggest harborage right there; scattered droppings across many cabinets suggest a larger population that has spread. Evidence only on the garage floor or near an exterior door points to outdoor species coming in rather than breeding inside.
How to Get the Most From an Inspection
- Don't deep-clean right before, droppings and smear marks help locate harborage
- Hold off on store-bought sprays for a few days beforehand
- Save a dead roach in a sealed bag or take a clear photo
- Think through when and where you've seen activity, including time of day
- Have access ready to under-sink cabinets, the water heater and the garage
How Findings Shape the Plan
An inspection usually lands in one of a few categories: an occasional outdoor visitor that calls for exclusion, an outdoor population pressing in from landscaping, or an established indoor population that needs a multi-visit program. Knowing which one you're dealing with is what keeps treatment proportionate, neither overdoing a minor issue nor underestimating an established one.
Types of Inspections
| Inspection type | When it makes sense | What's covered |
|---|---|---|
| Initial residential | First sightings or signs in a home | Kitchen, bathrooms, utility areas, exterior perimeter |
| Multi-unit / building | Reports from several units or recurring problems | Reporting units, adjoining units, common areas |
| Commercial | Restaurants, offices, retail, warehouses | Food-prep and storage, break rooms, receiving, exterior |
| Pre-purchase or pre-lease | Before buying or renting a property | Evidence of past or current activity, entry points |
| Pre-arrival (seasonal) | Before returning to a seasonal home | Whole-home check for activity that built up while empty |
| Follow-up | After treatment | Monitors, sighting notes, remaining harborage |
Tools a Specialist Typically Uses
- Flashlight: the most important tool, roaches and evidence hide in dark gaps.
- Inspection mirror: for looking behind appliances and under fixtures.
- Flushing agent (in some cases): a small puff into a crack to see whether roaches are sheltering inside.
- Sticky monitors: left in place to confirm activity levels over the following days or weeks.
- Moisture meter (sometimes): to find damp areas behind walls or under cabinets.
Much of an inspection is simply careful looking in the right places, the same places this site describes, combined with experience interpreting what's found.
Specialists usually avoid disturbing an area more than necessary during an inspection, since flushing roaches out of one hiding spot can push them into another. The goal is to map where they live so treatment can be placed accurately.
Inspecting Before You Buy or Rent
A general home inspection doesn't always look closely for cockroach activity, and a wood-destroying organism (WDO) inspection focuses on termites and similar pests. If you're buying or renting in Florida and want to know about cockroaches specifically, it can be worth a separate look. Signs of past or current German cockroach activity (droppings in cabinet corners, egg cases behind appliances, bait residue) are easiest to spot when the home is empty.
For a rental, a walk-through before signing lets you check under sinks and behind appliances yourself. If you find signs, raise them with the landlord before you move in and ask whether the unit was inspected or treated at turnover.
Questions You'll Likely Be Asked
- When did you first notice activity?
- Where and at what time of day have you seen roaches?
- How big were they, and what color?
- Have you used any sprays, foggers, baits or powders?
- Have you brought in secondhand furniture, appliances or boxes recently?
- Are there any leaks or moisture problems you know of?
- In a shared building, have neighbors mentioned anything?
Thinking through these before the visit makes the inspection faster and more accurate.
What's Different About Commercial Inspections
Commercial inspections usually happen outside business hours and cover more ground: food-prep areas, dish stations, floor drains, dry storage, break rooms, restrooms, receiving areas and the exterior around dumpsters and rear doors. The specialist may ask to see any sighting log staff have kept and will often want to look behind and under equipment that doesn't normally move. The result is typically a written summary of findings and a proposed service schedule rather than a one-time plan.
What an Inspection Can't Always See
Even a thorough inspection has limits. Roaches deep inside wall voids, under slab-level cabinets or in neighboring units may not be visible, and a single visit captures only one moment in time. That's why specialists often place monitors after the inspection and ask you to note where and when you see activity. Those extra data points fill in what one visit can't show.
What an Inspection Summary Usually Includes
- The species identified, or the most likely species if no live roaches were found
- Where activity and evidence were concentrated
- Conducive conditions: moisture, clutter, food sources, entry points
- A recommended approach and whether follow-up is expected
- Sanitation and exclusion steps you can take yourself
- Pricing for the proposed work, discussed before anything begins
If the summary is verbal, it's worth jotting down the main points or asking for them in writing, especially for rentals, businesses or condo associations that need records.
A Do-It-Yourself Check Before You Call
If you're not sure whether you need an inspection, a 15-minute check after dark can help you decide. Use a flashlight to look under the kitchen sink, behind the refrigerator, inside the oven drawer and under the bathroom vanity. Look for live roaches, pepper-like droppings, brown smear marks, shed skins and egg cases. If you find small tan roaches or signs of breeding in cabinets, an inspection is worthwhile. If you only find a single large roach near a door, sealing the entry point may be enough, though a specialist can confirm either way.

Frequently Asked Questions
This varies by property size and complexity, a specialist can give you an estimate when scheduling.
Being present is generally helpful so you can point out where you've seen activity, though a specialist can advise on specifics.
Often, yes, a specialist can usually explain a proposed approach shortly after the inspection is complete.
Pricing is discussed upfront before any work begins. Ask directly when you call.
Normal tidying is fine, but avoid wiping away droppings or residue in cabinets. They help the specialist locate harborage.
Yes. A specimen or clear photo makes species identification quicker and more certain.
Usually. The exterior perimeter is where many entry points and outdoor sources are found.
That's useful information too. It may point to an occasional outdoor visitor rather than an established population.
It can give a rough sense, multiple life stages and heavy droppings generally suggest a more established population.
Not necessarily. A WDO inspection focuses on termites and similar wood-destroying pests, so ask for a cockroach-specific look if that's a concern.
