You got a notice: pest control is coming to your apartment on Tuesday, empty your cabinets and kennel your pets. So where will they actually spray, will they come inside without you, and is it safe to stay? The answer depends on whether it's routine service or a treatment for a specific pest. This guide is for renters. It covers what a technician usually treats in an apartment, what research shows actually works for apartment cockroaches, your notice rights in South Carolina and Virginia, and what to do before and after.
Routine apartment service often focuses outside: the foundation, doorways, windows and outdoor bait stations. When technicians come inside, they usually treat the kitchen and bathrooms, along baseboards, under sinks, around plumbing and behind appliances, where cockroaches and ants live. Bedrooms are usually treated only for a specific problem, like bed bugs.
For cockroaches, bait matters more than spray. StopPests, a HUD-funded program on pest control in housing, says baits "have generally replaced fogs and sprays" for cockroaches in housing. Expect small dots of gel in cabinet hinges and cracks, and don't wipe them away.
Where Pest Control Treats in an Apartment
| Area | Routine service | When there's a problem |
|---|---|---|
| Building exterior | Foundation, doorways, windows, weep holes and landscaping beds | More frequent exterior treatment for ants, spiders and occasional invaders |
| Outdoor bait stations | Checked and refilled around the buildings | Added stations near dumpsters and entry points for rodents |
| Kitchen | Often not treated unless requested | Gel bait in cabinet hinges and cracks, treatment under the sink, around plumbing and behind the stove and refrigerator |
| Bathrooms | Often not treated unless requested | Around pipes, under the vanity, behind the toilet |
| Baseboards and entry points | Sometimes, as a preventive treatment | Crack-and-crevice treatment where bugs are getting in |
| Bedrooms | Usually not | Bed bug treatment: mattress seams, bed frames, furniture and nearby cracks |
Product labels shape all of this. Most indoor insecticides are applied as spot or crack-and-crevice treatments, not sprayed across open floors and walls. For a room-by-room look at a whole-house visit, see where pest control sprays in a house.
What a Visit Actually Looks Like
A pest control technician who posts on YouTube filmed a typical day, including an apartment complex stop (about 114,000 views). His job there was servicing five tenants who had reported problems. For cockroaches, he sprayed around the kitchen and put out cockroach bait. For spiders, he treated along the baseboards. For ants, he treated around the kitchen. "Didn't take very long," he said. Then he walked the property servicing about 80 outdoor rodent bait stations.
Renters describe the same range. In Reddit threads on apartment pest control (via Google search excerpts), one wrote that routine preventive service "just do[es] the baseboards in the kitchen and bathroom." Another complex scheduled pest control "once per month for all residents." And one renter complained that the technician comes in about once a month, sprays "two corners of the kitchens and just walks right back out."
Why Spraying Baseboards Doesn't Fix Apartment Roaches
That "two corners" complaint points to a real problem. German cockroaches, the kind that live inside apartments, have become highly resistant to common sprays. NC State researchers tested cockroaches from apartments where bug bombs had failed and found them about 202 times more resistant to the pyrethroid cypermethrin than a susceptible lab strain. Gel baits did much better in the same study, cutting populations by about 70% to 93% within a month.
A pest control worker summed it up in a Reddit thread: a building had its baseboards sprayed every two weeks without fixing anything, but after one application of gel bait there were no more roaches within two or three weeks. That's one account, but it matches the research and StopPests' guidance that baits are the main tool in housing.
If you have cockroaches and your service is only spraying baseboards, ask for a cockroach treatment with baits and follow-up visits. Rutgers researchers found that traps placed by the stove and refrigerator caught significantly more cockroaches in apartments than traps under the sink or in the bathroom, so those spots matter.
Do They Have to Tell You Before Coming In?
It depends on your state and your lease.
- South Carolina: a landlord may enter without your consent between 9 a.m. and 6 p.m. for regularly scheduled services, including "termite, insect, or pest treatment," but only if the lease spells this out conspicuously (S.C. Code § 27-40-530).
- Virginia: the landlord must give you at least 72 hours' notice of routine maintenance you didn't request, and the work must happen within 14 days of the notice (Va. Code § 55.1-1229).
- North Carolina and everywhere else: check your lease for entry and notice terms.
You usually don't have to be home. Many complexes let the technician in with a master key while you're at work. If you'd rather be there, ask the office for a time window.
How to Prepare Your Apartment
- Read the notice. Some treatments, especially for cockroaches, ask you to empty kitchen and bathroom cabinets so the technician can reach the cracks and hinges.
- Clear the edges. Move items away from baseboards, and pull small appliances off the counter if you've seen roaches behind them.
- Secure pets in a kennel or a closed room, and cover fish tanks.
- Put away food, dishes, toothbrushes and pet bowls.
- Leave a note listing where you've seen bugs and what kind.
- Don't spray your own products first. In a 2016 study of over 2,000 apartments, 59% of residents with bed bugs had already used insecticides themselves. NC State's housing office warns that do-it-yourself pesticides can make professional treatments less effective.
After the Visit
- Stay off wet surfaces. As the top answer in a Reddit pest control thread put it, the main concern is "people or animals touching the sprays while wet." Keep kids and pets out of treated areas until they're dry.
- Leave gel bait dots alone. They're meant to be eaten. A 2025 University of Kentucky study found that wiping nearby surfaces with ordinary cleaners didn't stop baits from working, so you can clean your kitchen as normal. Just don't wipe off the bait. The exceptions in that study were DEET, an essential-oil product and a pyrethrin flushing spray, which did reduce bait performance, so keep those away from bait.
- Clean up food sources. The same study found competing food reduces how well baits work. Crumbs, grease and pet food left out give roaches something else to eat.
- Expect to see bugs for a few days as they come out and contact the treatment. Report live activity that continues two weeks later.
- Tell the office if it keeps coming back. In shared buildings, cockroaches and bed bugs move between units, so the neighbors may need treatment too.

Key Takeaways
- Routine apartment service often focuses on the exterior: foundation, doors, windows and bait stations.
- Inside, treatment targets kitchens and bathrooms, under sinks, around pipes and behind appliances. Bedrooms are usually treated only for bed bugs.
- Baits beat sprays for apartment cockroaches. Apartment roaches in an NC State study were about 202 times more resistant to a common spray.
- Notice rules: SC allows 9 a.m. to 6 p.m. entry for pest treatment if the lease says so. Virginia requires 72 hours' notice for routine maintenance.
- After treatment, stay off wet surfaces, leave bait dots alone, and report bugs that continue after two weeks.
Frequently Asked Questions
Routine service often focuses on the outside: the foundation, doorways, windows and outdoor bait stations. Inside, technicians usually treat kitchens and bathrooms, along baseboards, under sinks, around plumbing and behind appliances. Most indoor products are applied as spot or crack-and-crevice treatments rather than sprayed across open surfaces.
Usually not during routine service. Bedrooms are typically treated for a specific problem, most often bed bugs, when the technician treats mattress seams, bed frames, furniture and nearby cracks. If you're seeing bugs in a bedroom, tell the office so it's included.
Not always. Many routine visits are exterior only, and interior treatment is often done for units that report a problem or when the property schedules it. If you're seeing bugs inside, ask the office to add your unit.
Usually not. Many complexes let the technician in with a master key. In South Carolina, a landlord may enter between 9 a.m. and 6 p.m. for scheduled pest treatment without your consent if the lease conspicuously says so. In Virginia, routine maintenance you didn't request requires at least 72 hours' notice.
It varies by property. Many complexes schedule monthly or quarterly service, and units with an active problem get extra visits. Cockroach and bed bug treatments usually need follow-ups about two weeks apart.
It depends on the property's schedule, so check your notice. In South Carolina, entry without consent for scheduled pest treatment is limited to 9 a.m. to 6 p.m. and only if your lease allows it.
Follow the technician's instructions and the product label. The main precaution is keeping people and pets off treated surfaces until they're dry. Keep kids and pets out of treated areas until then, and cover fish tanks during the visit.
German cockroaches in many apartments are resistant to common sprays. NC State researchers found apartment cockroaches about 202 times more resistant to a common pyrethroid, while gel baits cut populations about 70% to 93% in a month. Ask for a bait-based cockroach treatment with follow-ups, and tell the office if neighbors have them too.
Yes, but leave the bait itself alone. A 2025 University of Kentucky study found baits kept working when contaminated with ordinary cleaning products. The exceptions were DEET, an essential-oil product and a pyrethrin flushing spray. Removing crumbs and food helps, because competing food makes baits less effective.
Read the notice first. Common steps are emptying kitchen and bathroom cabinets for cockroach treatment, clearing items away from baseboards, securing pets, putting away food, dishes and toothbrushes, and leaving a note about where you've seen bugs. Don't spray your own products beforehand.
