The short answer
Clean, seal, then bait: small gel bait placements in the cracks where cockroaches hide. Spraying open surfaces often fails, because it scatters them and can spoil the bait. The species matters more than the count. A German cockroach breeds indoors and means an infestation. Most large ones that wander in from outside do not.
Key takeaways
EPA: “Droppings or body parts of cockroaches and other pests can trigger asthma.” That is the reason to act.
“Keep counters, sinks, tables and floors clean and free of clutter. Clean dishes, crumbs and spills right away. Store food in airtight containers. Seal cracks or openings around or inside cabinets.”
Small, breed indoors, and the usual cause of a kitchen problem that keeps coming back. The large ones seen after rain usually come in from outside.
Cockroaches carry bait back and share it. A repellent spray pushes them into wall voids and can spoil the bait.
They coat open surfaces. Cockroaches live in cracks the fog never reaches.
Sticky monitors counted at each visit tell you whether the work is working. See integrated pest management.
How do I know I have cockroaches?
Cockroaches come out at night and hide in tight cracks, so what they leave behind tells you more than what you see.
Like ground pepper or coffee grounds, at the back of cabinets, in drawer runners, under the sink and along the top edge of cupboard doors.
In corners and on upright surfaces in damp spots.
Small, ridged, purse-shaped capsules glued into cracks, behind the fridge motor, under the counter lip and inside appliances.
Different sizes mean a breeding population, not one stray.
In a closed cupboard, once numbers are high.
Cockroaches are night insects. Seeing them by day usually means a large population short of hiding places.
Which cockroach is it, and does it breed indoors?
The species decides whether this is a few weeks of sealing or a program of several visits. A clear photo is usually enough. Our pest identifier helps you narrow it down.
| Species | What it means for you |
|---|---|
| German cockroach | Small and tan, with two dark stripes behind the head. Breeds indoors in warm, humid kitchens and bathrooms. Behind most household infestations, and the one that needs a proper bait program. |
| American cockroach | Large and reddish-brown. Usually lives in sewers, drains, crawl spaces and basements, and comes up. Often a drain or crawl-space question, not a kitchen one. |
| Oriental cockroach | Dark, glossy and slow. Found in damp, cool places such as basements, drains and under porches. Often a moisture and drainage finding. |
| Brown-banded cockroach | Small, with bands across the wings. Spreads through the whole home, not just the kitchen and bathroom, so bait has to cover more rooms. |
| Wood and other outdoor species | Wander in and do not settle. This is about sealing. Repeat visits to one room point to one gap. |
What should a technician inspect?
A good cockroach inspection takes a flashlight, a mirror and some taking apart. Anyone who sprays a baseboard and leaves has inspected nothing.
Behind and under the refrigerator, including the motor housing, and behind the dishwasher and stove.
The cabinet floor, where the pipe goes through the wall, and the gap behind the kick plate.
Hinge recesses, drawer runners and the underside of counter lips.
The base of a coffee maker, toaster or microwave. Common hiding places that are often missed.
A slow drain leak, a sweating cold pipe, a leaking dishwasher seal, a damp basement or crawl space.
Pipe and wire openings, drain lines, shared walls in apartment buildings, and cardboard boxes brought into the house.
What does cockroach treatment involve?
The work is a sequence. Every step before the bait raises the odds that the bait works.
Where they hide, roughly how many, and whether this species breeds indoors. Sticky monitors placed now give a starting count.
EPA’s list comes first: clean surfaces, food sealed away, cracks sealed. Cardboard matters most. It is both a hiding place and how cockroaches arrive.
Seal cabinet gaps, the pipe opening under the sink and hollow spaces behind the kick plate, and fix the slow leak. This decides whether month three is quiet.
Many small placements, right in and beside the hiding places found in step one. Not a line along a baseboard. Placement is the whole technique.
A repellent sprayed across bait makes it unattractive or out of reach. Ask whether anything will be sprayed, and where.
Sticky monitors counted at every visit. This turns “it feels better” into a number, and shows a working program from a stalled one.
What is being applied in your home
Here the health case and the chemical case point the same way. EPA says “Certain proteins are found in cockroach feces and saliva and can cause allergic reactions or trigger asthma symptoms in some individuals.”
It also warns: “Insecticides and pesticides are not only toxic to pests — they can harm people too.” It names cleaning and sealing as the better first step. See pesticide safety in the home.
Tell the company before the visit if anyone has asthma or a breathing condition. It should change the method.
The product name, its EPA registration number, and whether it is a gel bait, a dust or a residual spray.
Exactly where anything goes near food preparation, and what the label allows there.
When you can go back in, and whether bait sits where a dog can reach it.
Whether dust goes into wall voids or under appliances, and whether it can drift into living space.
Total-release foggers suit this insect poorly and carry their own hazards. If one is suggested, ask why.
A pesticide label is a legally enforceable document, not packaging copy: it is a violation of federal law to use a product in a manner inconsistent with its labeling. The full explanation is on pesticide safety in the home.

What moves the price
Price follows the rooms involved, the state of the home and the number of visits. Clutter and unfixed leaks move the total most.
| Factor | Why it changes the number |
|---|---|
| Species | A German cockroach program takes several visits. An American cockroach coming up a drain is often a drain cover and a door sweep. |
| Rooms involved | Brown-banded cockroaches spread through the home, which multiplies the placements. |
| Clutter and access | Every hiding place is a placement. A kitchen that cannot be opened up cannot be treated properly. |
| Visits included | Ask for a number, not “as needed”. A serious German cockroach job is usually several visits over weeks. |
| Leak repair | Not usually the pest company’s work, and usually what decides whether treatment holds. |
| Apartment buildings | Cockroaches travel along shared pipes and walls. Treating one unit in an infested building buys time. Coordinating the building is the landlord’s job. |
| Monitoring | Sticky monitors cost very little and are the honest measure of progress. Insist on them. |
HyrePest publishes no average price for this work and holds no dataset of pest control invoices. Species, severity, construction, regional pressure and whether the job is sold as a one-off or a contract move the number far enough that a single figure would mislead.
Ask for a monitor count, not reassurance
Monitors placed at the first visit and counted at every visit after make this measurable. A count that falls over three visits is a working treatment.
A flat count while the technician says it is improving is worth raising early, while the contract still gives you leverage. See pest control contracts for the terms to check.
What to ask before you sign
Which cockroach is this, and does it breed indoors?
Will you place monitors and give me the counts at each visit?
Are you baiting or spraying, and will anything be sprayed near the bait?
What is the product name and EPA registration number, and what goes near food surfaces?
Someone here has asthma. How does that change what you use and where?
How many visits are included, and over what period?
What sealing and leak repair do you recommend, and who does it?
When can we go back in, and what about pets?
If this is an apartment, will you talk to the building about the units next door?
What would tell us at visit three that this is not working?
What to have ready
It is a hiding place and how cockroaches usually arrive.
Wipe them and leave them empty until after the visit.
Repair or report the slow leak under the sink before treatment, not after.
Use airtight containers, clean crumbs and spills right away, and put pet food away overnight.
Droppings and egg cases where you found them, before cleaning, so the technician knows where to look.
Say up front if anyone has asthma or a breathing condition.
Where this goes wrong
Foggers coat open surfaces. Cockroaches live in cracks, so fog usually pushes them deeper and into the next room.
A repellent across the bait cancels the one treatment that reaches the population.
Every box and gap is a hiding place. Treating around clutter is treating around the problem.
Cockroaches need water more urgently than food. A slow leak under the sink will outlast any bait.
Sightings drop before the population does. Count monitors instead.
Cockroaches move through shared walls and pipes. Without the units next door, you manage the population rather than remove it.

Primary-source research and fact checking
We are not a pest control company. We read the pesticide label rule, the agency guidance and the state board record ourselves, and publish each point with its source and the date we retrieved it.
Where a claim cannot be traced to a primary source, we leave it out and say so. We hold no dataset of pest control prices, so we publish no average price.
- 25
- primary-source pages (EPA, CDC, eCFR, state boards) behind the fact base
- 7
- common claims we checked, could not verify, and do not repeat
- 10
- calculators that use your numbers, not a national average
- 0
- average prices published, because we hold no price data
How this desk works
- Primary sources only. Label law comes from FIFRA and 40 CFR 156, safety guidance from EPA and CDC, licensing from the state board that issues the license. We do not cite an article that cites a source.
- Every figure carries its retrieval date. Agency pages and board rules change. A statement without the date it was read cannot be checked.
- Identify before treating. We describe what separates one pest from another and what a good inspection looks at. We never diagnose a species from a description, and we never give pesticide application instructions.
- What we could not verify is published too. Claims that circulate widely but trace to no current primary source are listed and left out of the pages.
Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.

Information on this page is general and varies by species, region, construction and your own circumstances. It is not pesticide application advice, and a pesticide label is a legally binding instruction that takes precedence over anything written here.
HyrePest is not a pest control company: we inspect nothing, treat nothing, apply no pesticide and bond no structure. This page explains the work so you can read a proposal and judge the company that wrote it.
