Overview
A clean counter can hide a leaking pipe below the sink. For cockroaches, access to food and water matters, but so does finding the species and the places it is active. Prepare the area the provider asks to see and keep a record of catches, rather than emptying every cabinet on a generic schedule.
Why This Matters
UC IPM recommends sticky traps to find and monitor cockroach activity. It also notes that sprays alone do not eliminate an infestation. A useful prep plan joins three tasks: show where insects are appearing, remove easy food and water, and make the treatment sites reachable without moving pests through the building.
1Record sightings before you clean
Photograph a specimen if possible and note its size, the room, and the time. Cockroach species differ in where they live and how they enter, so save a trapped insect for identification when the provider requests one. Put numbered sticky monitors along walls near suspected activity, out of reach of children and pets. Record the location and catches at each check.
- Look near plumbing, appliances, cabinets, and other dark places that can be reached safely.
- Record leaks and condensation alongside sightings so maintenance can fix them.
- In a managed building, keep reports by unit and common area rather than merging them into one count.
2Clean the food and water sources
Store food in closed containers, remove crumbs and spills, empty trash, and arrange repair of leaks. Clean reachable areas around appliances without pulling a heavy stove or refrigerator yourself. Remove excess paper bags and cardboard that create hiding places. These steps help treatment work and may reduce activity while you wait, but they do not confirm that the infestation is gone.
Give maintenance a dated leak location, such as “cabinet floor under the kitchen sink,” so the repair can be checked against later trap catches.
3Confirm exactly what to move
Ask the provider which cabinets, drawers, and appliances need access for the proposed method. If food or utensils must be moved, ask where to store them and when they can return. Request instructions for pets, aquariums, re-entry, and cleaning after treatment that match the products used. Do not remove electrical covers or move large appliances unless a qualified person directs the work.
- Clear requested work areas while keeping items from different rooms separate.
- Tell the provider about any sprays or baits already used.
- Ask which surfaces must remain undisturbed and for how long.
4Check whether the plan worked
Keep the same monitor locations after treatment and compare catches over time. A single quiet night is not proof of control. If catches continue, send the provider the trap record, leak status, and new sightings so they can reassess identification, access, and treatment. A 2009 study in New York public housing found fewer cockroaches after a program that combined cleaning, sealing, targeted treatment, and resident instructions than after routine service; the bundled study cannot tell us which one step made the difference. In a separate 2019 North Carolina home study, total-release foggers failed to lower cockroach counts and raised measured surface residues. Neither study predicts a particular result in this home.
- Compare catches by the same trap location and similar check periods; replace a moved or damaged trap before drawing a trend.
- Ask whether continued catches point to a missed source, a leak, or activity in an adjoining unit.
- Record the next agreed check date and who will make any needed repair.
Key Takeaways
- 1Save a specimen or clear photo and record where activity occurs.
- 2Use numbered sticky monitors to show where treatment should focus and whether it worked.
- 3Fix leaks and remove food, trash, and hiding places.
- 4Follow the provider’s instructions for the actual method before emptying cabinets.
Frequently Asked Questions
Should I empty every kitchen cabinet?
Ask the provider which spaces must be opened for the chosen treatment. The answer can change with the species, the activity map, and the application method.
Are sticky traps a treatment?
UC IPM recommends them to detect and track cockroaches. They help locate activity and measure change, but a trap record alone is not a complete control plan.
Should I spray before the visit?
Tell the provider what has already been applied and follow the product label. UC IPM says sprays alone do not eliminate cockroaches; broad spraying can also interfere with a targeted plan.
