How to Get Rid of Roaches in an Apartment: A Tenant's Plan

The best way to get rid of roaches in an apartment is to bait your own unit thoroughly, seal the gaps around pipes and wires that connect you to neighbors, and report the problem to management in writing so the building can be treated. Clean up food, clutter and water every night, and monitor with at least six traps.

Why Apartments Make Roaches Harder

In a house, you control the whole building. In an apartment, roaches move between units through holes and cracks in shared walls and ceilings, and along plumbing and wiring runs. Purdue Extension's guide to cockroach control in multi-family housing stresses that good control cannot be achieved without cooperation among residents, management and the pest control company.

That does not mean you are powerless. A clean, well-baited, well-sealed unit is a poor place for roaches to live, and the ones arriving from next door eat bait instead of breeding. It does mean that one tenant working alone in a badly infested building can keep the numbers down but may not reach zero.

Our main guide on how to get rid of roaches covers species and methods in depth, and the getting rid of roaches section links the other room-by-room guides.

What You Need

• Sticky traps: at least six, the minimum Purdue recommends for monitoring a home.
• Gel bait and bait stations: gel for cracks, stations where children or pets could reach.
• Boric acid and a small duster: for voids behind appliances.
• Caulk, expanding foam and copper mesh: for gaps around pipes, wires and cabinets.
• Sealed food containers and a lidded trash can: to take away food.
• A flashlight and a phone camera: to find hiding spots and document the problem for your landlord.

Most of this is renter-friendly: traps, stations and caulk around pipes under the sink do not damage the unit and come out easily when you move.

How to Get Rid of Roaches in an Apartment

1. Document and report: photograph roaches, droppings and traps, and send management a written report with dates and locations.
2. Inspect with a flashlight: at night, check behind the fridge, under the sink, around the stove and in closet corners, and note where droppings collect.
3. Set at least six traps: along floor-wall edges in the kitchen, bathroom and near the entry door, and check the counts every few days.
4. Clean and declutter: wash dishes promptly or leave them under soapy water, cover food, pet food and trash, and clear out cardboard, bags and stacked paper.
5. Bait the hiding spots: put pea-sized dabs of gel in many cracks and corners where roaches hide, using a peanut-sized dab where numbers are high, and place stations where kids or pets play.
6. Dust behind appliances: apply a sparing film of boric acid behind the stove and refrigerator and in voids under the sink, kept dry and away from counters.
7. Seal the shared gaps: caulk or foam around pipes under the sink and behind the toilet, around wires and outlets, and where cabinets meet the wall, and stuff larger holes with copper mesh.
8. Recheck in one to two weeks: compare trap counts, add bait where it has been eaten and tell management if numbers are not falling.

Bait Stations or Gel in a Rental

Most apartments need a mix: gel deep in kitchen cracks, stations where little hands and paws go and a light dusting behind appliances. Purdue notes that a combination of bait and dust often gives the best results. Avoid foggers in an apartment altogether: the fog does not reach the cracks, and it can push roaches through the walls toward your neighbors.

Working With Your Landlord

Report roaches early and in writing, even if you are treating them yourself. Roaches in your unit usually mean roaches in the walls and nearby units, and building management is the only party that can arrange treatment of the units around you, common areas and trash rooms.

Include photos, trap counts and where you see the most activity, and mention leaks or damaged walls, since Purdue lists fixing water leaks and sealing cracks among the steps that matter. Keep copies of everything in case the problem drags on.

When a pest control company comes, prepare the kitchen so they can reach under the sink and behind appliances, and ask them to use baits rather than broad spraying, which can drive roaches into your neighbors' units and back again.

Keeping Roaches Out of Your Apartment

Sealing is the long-term defense in an apartment. University of Kentucky entomologists note that sealing pipe and wire openings with caulk, foam or copper mesh reduces the movement of roaches between adjoining units, and those gaps are often the main route in.

• Keep the kitchen dry: fix drips and dry the sink at night.
• Bag trash daily: take it to the building's bins rather than leaving it by the door.
• Check deliveries and secondhand items: roaches arrive in boxes and used appliances.
• Leave a few traps out: an early catch means it is time to bait again.

If you are moving in, seal and trap before you unpack; it is far easier to caulk an empty sink cabinet than a full one.

Common Questions About Roaches in Apartments

Key Takeaways

Roaches in one apartment are rarely confined to it, so success depends on two fronts at once. Inside your unit, bait, dust, sealing and nightly cleanup make it a poor place to live; across the building, management has to deal with the units and spaces you cannot reach.

Report the infestation to management in writing with photos and trap counts, and push for treatment of adjoining units if your traps show roaches arriving from next door. If counts are still high after a month of steady work, a building-wide treatment by a licensed professional is the realistic next step.

Today, set six sticky traps around the kitchen and bathroom and send management a dated photo of what you have found.
