After a few weeks of store sprays and sticky traps, a lot of homeowners reach the same question: if I call someone, what will the exterminator actually do for roaches? Will they just spray the kitchen and leave? How many visits does it take? What do I need to do before they show up?
Here’s what a professional roach visit looks like from start to finish in a Treasure Valley home or business, step by step, so you know what you’re signing up for before you pick up the phone.
Step 1: A Few Questions on the Phone
The process starts before anyone arrives. Expect questions like where you’re seeing roaches, what time of day, how big they are, and how long it’s been going on. A small tan roach in the kitchen at night points to German cockroaches, which is what most indoor roach calls in the Treasure Valley turn out to be. A large dark roach near a floor drain or in a basement is a different situation. If you’re not sure what you’re seeing, our cockroach identification guide can help you describe it.
Step 2: Prep Before the Visit
You’ll usually be asked to do a little prep so the technician can reach the places roaches live:
- Empty the cabinets under the kitchen and bathroom sinks
- Clear counters around the stove, toaster, coffee maker and microwave
- Put food in sealed containers
- Stop using store sprays a few days before the visit, since they can scatter roaches and interfere with treatment
- Plan to keep pets out of the work area during the visit and follow the technician’s re-entry instructions
Step 3: The Inspection
The first part of the visit is mostly looking, not treating. German roaches spend most of their lives hidden in warm, tight spots near food and water, so the technician’s job is to find those harborage areas. That means a flashlight and a lot of opening things up: drawers, cabinet hinges and corners, under and behind the refrigerator, dishwasher and stove, inside appliance housings, and along plumbing lines where they pass through the wall under sinks.
Droppings that look like ground pepper, shed skins and egg cases show where activity is concentrated. Sticky monitoring traps are often set to confirm hot spots and give a baseline to compare against later.
Step 4: Targeted Treatment
This is the part most people picture, but it looks different than you might expect. A professional roach treatment isn’t a fog or a wall-to-wall spray. Product goes where the roaches live and travel, not across open counters and floors. Depending on what the inspection finds, that can include:
- Small placements of gel bait in cracks, hinges and corners
- An insect growth regulator to interrupt the next generation
- Fine dust in wall voids, behind outlet covers and under appliances
- Targeted crack-and-crevice applications of non-repellent products, so roaches don’t scatter into new rooms
- Vacuuming heavy activity out of harborage areas before treatment
We cover the products themselves, and what each one does, in what chemicals exterminators use for roaches. This post is about the process around them.
Step 5: Fixing What’s Feeding Them
A good technician will also point out the conditions that keep roaches comfortable: a slow drip under the sink, grease buildup behind the stove, cardboard stored in the pantry, gaps around pipes. Treatment works much better when those get handled. This is the core of integrated pest management, the approach the EPA describes as combining inspection, targeted treatment, sanitation and monitoring.
Step 6: The First Couple of Weeks
It’s normal to see more roaches for a few days after treatment, including some out in daylight, as roaches come out of hiding and contact the products. That’s a sign things are working, not failing. During that stretch:
- Don’t wipe down treated cracks and hinges
- Don’t spray store products over treated areas
- Keep up with crumbs, dishes and grease at night
- Get any cardboard boxes out of the house
Step 7: Monitoring and Follow-Ups as Needed
The monitoring traps tell the story. If counts drop and stay down, that’s the goal. If they show continued activity, often from the egg cycle bringing up a new round of nymphs, the technician comes back as needed to re-inspect and treat the spots that are still active. There isn’t a fixed number of visits; it depends on how established the population was and how the home responds.
Do Exterminators Get Rid of Roaches?
Yes, when the process above is followed and the conditions around the roaches change too. Where DIY tends to stall is reach: store sprays hit the roaches in the open and push the rest deeper. A technician treats the spots you can’t see, picks products that don’t scatter them, and keeps checking until activity is gone.
Homes and Businesses
The same process works in restaurant kitchens, break rooms, offices and apartment buildings, where roaches can move between units or arrive with deliveries. We handle roach work for businesses through our commercial pest control in Boise and across the valley.
For homeowners, roach treatment is its own separate service. It isn’t covered by the quarterly plan in our residential pest control, and follow-up visits are scheduled as needed. We’ll walk you through what your situation needs before anything is scheduled.
