How Do You Get Rid of Cockroaches?

If you’ve spotted a cockroach or suspect an infestation in your apartment, you’re not alone and you can do something about it. This guide will help you identify roaches, recognize the signs of a problem, understand what’s attracting them, and show you how to get rid of cockroaches in an apartment once and for all.

How to identify cockroaches

Not all creepy-crawlies are cockroaches, but if you see something that checks these boxes, it probably is:

• Body shape: Flat, oval, and usually quick to dart out of sight.
• Color: Brown or tan shades are most common in homes.
• Size: German cockroaches are small (about ½ inch); American roaches can reach over 2 inches.
• Antennae: Long, twitchy, and always active.
• Wings: Present on some species, but don’t worry, they’re not great flyers.

While there may be more than 4,000 species of cockroaches around the globe (and about 30 that enjoy indoor living), knowing what you’re dealing with is step one in showing them the door.

Signs of cockroaches in your apartment

Cockroaches are sneaky and prefer the shadows, but they leave clues behind. Watch out for:

• Droppings that resemble coffee grounds or black pepper.
• Egg casings in warm, hidden areas like kitchen cabinets or behind appliances.
• Smear marks along baseboards, walls, or countertops.
• Shed skins from growing nymphs.
• Musty odor that lingers around infested areas.
• Daytime sightings usually means overcrowding, which is a sign of infestation.
  

What causes cockroaches in an apartment? 

Before we talk about how to kick cockroaches out, let’s talk about what brought them inside in the first place:

• Food crumbs and grease: Roaches are opportunistic eaters. Even the tiniest spills are an all-you-can-eat buffet.
• Leaky pipes or moisture: Cockroaches need water to survive. Drips and dampness attract them fast.
• Cluttered spaces: Paper piles, cardboard boxes, and mess give them cozy hiding places.
• Entry points: Cracks, gaps, and unsealed windows are easy access doors.
• Shared walls: In apartments, if one unit has them, others are vulnerable. This is especially true if the problem goes unchecked.

How to get rid of cockroaches in an apartment

Once you’ve confirmed their presence, it’s time to act fast. Here’s how to get rid of roaches in an apartment, step by step. 

1. Notify your landlord

Contact your landlord as soon as you suspect an infestation of cockroaches. In many cases, they are legally required to handle pest control in rental units and may arrange for professional extermination to stop the infestation from spreading to other apartments. Reporting the problem early also helps create a record of your concern, which can be important if the issue worsens. Be clear and prompt in your communication; include details about where you’ve seen roaches, when the sightings occurred, and any problem areas that might need immediate attention.

2. Clean as much as possible

Roaches are drawn to crumbs, grease, and spills. A spotless kitchen and bathroom can make your apartment far less welcoming to them.

• Wipe down countertops, stovetops, and cabinets daily to eliminate food residue.
• Sweep, vacuum, and mop floors regularly to remove hidden crumbs and grease.
• Clean under and behind appliances (especially the fridge, oven, and microwave) where gunk tends to collect.
• Empty pet food dishes and clean up spills as soon as possible.
• Store cereals, flour, snacks, and pet food in airtight containers.
• Take the trash out often and always keep bins sealed with tight-fitting lids.

3. Declutter your space

Cockroaches love to hide, so the less clutter, the fewer places they have to settle in. Clearing out unnecessary items can make a big difference in roach control.

• Break down and recycle cardboard boxes (roaches love cardboard).
• Store important papers in sealed plastic bins or file drawers.
• Keep closets, cabinets, and under-sink areas neat and organized.
• Minimize piles of laundry, shopping bags, or miscellaneous clutter on the floor.
• Avoid leaving dirty dishes in the sink or out on counters overnight.

4. Seal all entry points

Even the smallest gaps are open invitations for cockroaches. Sealing cracks and crevices helps block their access from neighboring units or the outdoors. Ensure you refer to your lease and obtain your landlord's permission before making any modifications to your apartment.

• Use caulk to fill gaps around baseboards, pipes, windows, and door frames.
• Install door sweeps to eliminate space beneath entry doors.
• Cover air vents and drain openings with mesh or screens.
• Inspect utility holes or under-sink areas where plumbing meets the wall.

5. Fix water leaks

Roaches need water even more than food, and leaky pipes or condensation can keep them alive even in a clean apartment. Eliminating moisture sources removes their source of water.

• Report leaks in faucets, pipes, and running toilets immediately.
• Wipe down sinks and counters before bed to prevent moisture buildup overnight.
• Use a dehumidifier if your apartment tends to be humid, especially in basements or bathrooms.
• Avoid overwatering houseplants or leaving standing water in trays.

6. Set traps and baits

Roach traps and baits are an effective way to monitor activity and reduce populations. While not a complete fix, they help reduce the number you’re seeing. Your landlord may even be willing to cover the cost of the traps as a preventative measure, so be sure to communicate your concerns.  

• Place sticky traps near sinks, under appliances, and along walls where you’ve seen activity.
• Apply gel bait in cracks, corners, and under cabinets where roaches hide.
• Replace traps and reapply bait regularly for consistent results.
• Use enclosed bait stations if you have pets or children to keep them away from the poison.
• Be sure to carefully read and follow instructions on traps and bait. 

7. Try natural solutions

If you don’t want to use chemicals in your space, there are natural options that still pack a punch. They’re slower acting but can help with mild infestations when used correctly.

• Sprinkle food-grade diatomaceous earth in corners, under appliances, and along baseboards.
• Apply a light layer of boric acid in dark, hidden areas, but avoid overuse, as the smell can deter roaches from walking through it.
• Keep these substances out of the reach of children, pets, and food preparation surfaces.
• Reapply after cleaning or vacuuming.

8. Call in the pros

If cockroaches keep coming back or you’re feeling overwhelmed, a professional may be just what you need. Professionals have the tools and expertise to handle the problem at its source.

• Contact a licensed pest control company for a full inspection and treatment plan.
• As mentioned in the very beginning, make sure to notify your landlord ASAP, as they may be required to cover the cost, especially in apartment buildings.
• A pro can pinpoint problem areas, use more effective treatments, and prevent re-infestation.
• Ask about follow-up visits to ensure complete eradication.
