How to Prevent Roaches in a NYC Apartment
02.07.2026
To make a NYC apartment less attractive to roaches, cut off the three things they come for: food, water, and hiding spots. Store all food in sealed containers, wipe crumbs and grease nightly, fix leaks and dry the sink before bed, empty trash daily, and seal gaps around pipes, radiators, and baseboards. Prevention reduces what draws them in; killing an active infestation is a job for your landlord and a licensed exterminator.
What you'll need
- Airtight food containers (glass or hard plastic with a gasket lid)
- A degreasing dish soap and microfiber cloths
- A small handheld vacuum or a broom for crumbs
- A trash can with a tight-fitting lid
- Copper mesh or steel wool for stuffing gaps
- Paintable acrylic caulk and a caulk gun (renter-friendly, removable)
- Foam door sweeps or draft-blocker strips
- Sticky monitor traps (to see where activity is coming from)
Step by step
- Seal the food supply. Move cereal, rice, pasta, sugar, flour, and pet food into airtight containers. Cardboard boxes and clipped bags are not barriers. In a small kitchen, this also frees up cabinet space.
- Clean up after every meal. Wipe counters and the stovetop, sweep or vacuum crumbs, and run a degreasing soap over the backsplash weekly. Grease behind the stove is a common draw in tight NYC kitchens.
- Dry out water sources. Roaches can go a while without food but not without water. Wipe the sink dry at night, don't leave standing water in the basin, fix dripping faucets, and report leaks under the sink to your landlord in writing.
- Take out trash daily. Use a lidded can, and don't let recycling with food residue pile up on the floor. Rinse cans and bottles before they sit.
- Block entry points. Stuff copper mesh into the gaps where pipes enter under the sink and behind the radiator, then caulk small cracks along baseboards and around outlets. These are the highways between apartments in an old building.
- Guard the front door. Add a foam sweep at the bottom if you can see daylight underneath. In a shared hallway, that gap is a direct route in.
- Monitor. Place a couple of sticky traps under the sink and behind the fridge. If they catch anything, you'll know where to focus and whether it's time to escalate.
What NOT to do
- Don't caulk over an active leak. Sealing a wet gap traps moisture and invites more problems. Fix the water first.
- Don't stuff a steam radiator valve or pipe joint with steel wool. These get hot and need clearance; keep mesh to cold pipe penetrations under the sink and use caulk only on the wall, not on the valve.
- Don't spray store-bought pesticide along painted baseboards or finished floors without reading the label. Many leave stains, and residue near food-prep areas is a real concern. Follow the product's directions exactly, or skip it.
- Don't stack cardboard boxes in a closet for storage. Corrugated cardboard holds warmth and glue that roaches feed on. Use plastic bins instead.
- Don't ignore the neighbors' side. In a multi-unit building, one clean apartment next to an infested one still sees traffic. Cleaning alone won't seal a shared wall.
When to call a pro
DIY prevention makes your apartment a poor target, but it can't clear an established infestation, and it can't fix a building-wide problem coming through shared walls and risers. If you're seeing roaches in daylight, finding them in more than one room, or spotting droppings and egg cases, that's beyond cleaning: notify your landlord in writing (in NYC, treating infestations is generally the owner's responsibility) and let a licensed exterminator handle the actual removal. What we can do is the deep, detail-level cleaning that removes the grease, crumbs, and grime that keep drawing them back.

FAQ
Does keeping my apartment clean guarantee no roaches?
No. A clean apartment is far less attractive because there's little food or water, but roaches travel through walls, pipes, and hallways between units. Cleaning reduces the draw; it doesn't seal you off from a building that already has them.
Why do I see roaches even though my place is spotless?
In older NYC buildings, they move between apartments through gaps around pipes, radiators, and outlets. If a neighbor has an issue, you may see stragglers regardless of how clean your unit is. Sealing entry points and telling your landlord helps.
Are roaches worse in apartments with steam heat?
Warmth and moisture attract them, and radiator pipes create both plus convenient gaps to travel through. Keep the area around radiators dry and clear, and seal the cold pipe penetrations under the sink rather than the hot valve itself.
Whose job is roach extermination in a NYC rental?
For infestations, treatment generally falls to the building owner under NYC housing rules. Report the problem to your landlord in writing and keep a copy. Your part is prevention and sanitation; the licensed treatment is theirs to arrange.
