How to Get Rid of Roaches

Roaches are the uninvited roommates who never buy groceries, never pay rent, and somehow still show up at 2 a.m. like they own the place. The good news: you can get rid of them. The better news: you can do it without turning your home into a chemical theme park.

This guide uses an Integrated Pest Management (IPM) approachmeaning you’ll combine smart cleaning, targeted treatments, and prevention so roaches don’t just “pause” their visits… they move out for good. Whether you’ve spotted one suspicious “scout” or you’re basically living in a roach reality show, the steps below will help you take back your kitchen (and your peace).

Step 1: Identify What Kind of Roach You’re Fighting (Because It Matters)

“Roach” is like saying “car.” Helpful? Sure. Specific? Not enough. Different cockroaches behave differently, and the best roach control plan depends on the species.

German cockroaches (the worst indoor offender)

Small (usually light brown), fast, and commonly found in kitchens and bathrooms. German cockroaches thrive indoors and reproduce quickly. If you see these, act immediatelythis is the species most likely to turn “one roach” into “a situation.”

American cockroaches (“water bugs” in disguise)

Large, reddish-brown, and often connected to basements, drains, crawlspaces, and sewers. They can wander indoors, especially in warm climates or after heavy rain.

Brown-banded cockroaches

Smaller, prefer drier areas, and may show up in bedrooms, living rooms, behind picture frames, inside electronics, or high shelves. They’re the “why is it there?” roach.

Oriental cockroaches

Darker, slower, and linked to damp, cool areas like basements and floor drains.

Quick ID tip: If roaches are mostly in the kitchen and bathroom and you’re seeing small ones at night, assume German cockroaches until proven otherwiseand move to the “bait-first” strategy below.

Step 2: Understand Why Roaches Keep Coming Back

Roaches don’t move in because they love your interior design. They show up for three reasons: food, water, and shelter. Take away even one of these reliably, and you reduce the infestation. Take away all three, and you start winning.

• Food: crumbs, grease film, pet food, trash, recycling residue, and even that “clean” toaster crumb tray.
• Water: leaky pipes, condensation, wet sponges, pet bowls overnight, and slow-draining sinks.
• Shelter: clutter, cardboard, gaps under cabinets, voids behind appliances, and wall cracks near plumbing.

And one more: neighbors. In apartments, townhomes, and connected buildings, roaches can travel through wall voids and plumbing chases. You can still control thembut you’ll need a slightly more strategic plan (see the multi-unit section below).

Step 3: Follow This Roach Elimination Plan (IPM That Actually Works)

If you want a plan that isn’t “spray everything and hope,” this is it. Do these steps in order. You’re building pressure on the infestation from multiple angles.

1) Inspect like a detective (5 minutes tonight, 30 minutes this weekend)

Roaches prefer tight, dark spaces. Start here:

• Under the sink (especially where pipes enter the wall)
• Behind the refrigerator and stove (the warm buffet zone)
• Inside cabinet corners and hinges
• Bathroom vanity, behind the toilet, near floor drains
• Pantry corners and around pet food storage

Look for: live roaches at night, pepper-like droppings, egg cases, shed skins, and that unmistakable “roachy” smell in heavier infestations.

2) Start with “food lockdown” (because bait works better when roaches are hungry)

This is where you win without spending a dime:

• Wipe counters and stove daily (grease film counts as food)
• Vacuum or sweep under appliances and along baseboards
• Store dry goods in airtight containers (yes, even cereal)
• Take trash out nightly; rinse recycling
• Feed pets on a schedule; don’t leave bowls overnight

Why it matters: If your kitchen is offering free snacks, roaches won’t bother with your bait. You want your bait to be the best restaurant in town.

3) Cut off water (the “why are they still here?” game-changer)

• Fix leaks and slow drips (even a tiny drip is a roach water fountain)
• Dry the sink overnight
• Wring out sponges; don’t leave wet dishcloths on the counter
• Use a dehumidifier in damp basements if needed

4) Declutter and remove hiding places (especially cardboard)

Roaches love clutter because it creates warm, undisturbed harborage. Focus on:

• Cardboard boxes (replace with plastic bins)
• Paper piles, grocery bags, and “I’ll recycle it later” stacks
• Cabinet overcrowding (give roaches fewer protected corners)

5) Seal entry points (you’re not “locking them in,” you’re locking new ones out)

Use silicone caulk or appropriate sealant for:

• Gaps under sinks where plumbing enters walls
• Cracks along baseboards and cabinet edges
• Holes around electrical outlets (use safety-approved methods)
• Gaps behind the stove backsplash area and around counters

Pro tip: If you can slide a credit card into a gap, a roach can probably throw a party in it.

6) Set sticky traps (your “intel system”)

Sticky traps aren’t the main weapon for big infestations, but they are excellent for:

• Confirming where roaches are most active
• Monitoring if your plan is working
• Catching the occasional straggler

Place them under the sink, behind the fridge, and along wall edges. Check weekly and note where catches are highest.

7) Use gel bait correctly (this is the MVP for German roaches)

If you only do one “treatment” step, do this one well. Gel baits and bait placements are often more effective than blasting sprays everywhereespecially for German cockroach infestations.

How to apply bait (the right way):

• Use many small dots (think pea-size or smaller) instead of big globs.
• Put bait in cracks and crevices where roaches travel: cabinet hinges, corners, under sink edges, behind drawers, and behind appliances.
• Keep bait placements away from areas you’ll scrub daily (you don’t want to wipe it off).
• Re-check in about a week and reapply where bait has been eaten or dried out.

Important: Don’t spray harsh cleaners or insecticide sprays right on top of bait placements. Repellents can make roaches avoid the area and skip the bait.

8) Rotate bait actives (because roaches are stubborn, not magical)

In some regions and buildings, German cockroaches show bait aversion or resistance. If you’re not seeing results after consistent baiting and sanitation, switch to a bait with a different active ingredient classification. Rotation can improve results and reduce resistance issues over time.

9) Add an IGR for heavy infestations (roach birth control, basically)

Insect Growth Regulators (IGRs) disrupt roach development and reproduction. They don’t usually kill immediately, but they can make your overall plan dramatically more effective in stubborn infestationsespecially in apartments where new roaches may keep arriving.

10) Use dusts in the right places (dry, hidden, and very lightly applied)

Dusts like boric acid or silica/diatomaceous earth can be useful in wall voids, under appliances, and deep cracksplaces roaches travel but you don’t touch daily.

Dust rules:

• Less is more. A light, barely visible layer works better than a thick pile.
• Keep dust dry. Moisture reduces effectiveness.
• Avoid contaminating bait zones with dust or sprays.
• Follow label directions and keep products away from kids and pets.

11) Vacuum the “hot spots” (yes, vacuuming roaches is a thing)

This sounds ridiculous until it works. A strong vacuum with a crevice tool can remove roaches, egg cases, and crumbs from tight spaces. Vacuum:

• Behind the fridge motor area and drip pan zone
• Under the stove
• Cabinet corners and toe-kicks

Immediately empty the vacuum contents into a sealed bag and take it outside. This is not the time to be generous.

Step 4: What NOT to Do (Common Mistakes That Make Roaches Worse)

Don’t rely on bug bombs (total-release foggers)

Foggers can be a problem for two big reasons: they don’t penetrate the cracks where roaches hide, and they can create unnecessary exposure risks if used improperly. If you’ve ever set off a fogger and then still saw roaches strutting around like nothing happened… that’s sadly common.

Don’t spray everything in sight

Sprays can kill roaches you hit directly, but they often don’t solve the infestation. Worse, sprays used near bait can reduce bait effectiveness by repelling roaches from treated areas.

Don’t mix “all the things” at once

More products doesn’t always equal better results. A solid strategy beats a chemical cocktail. Start with sanitation + bait + monitoring, then add dust/IGR where appropriate.

Don’t ignore the “one roach”

One roach can be a random hitchhiker… or it can be the first clue. If you see one at night in the kitchen, set traps and inspect within 24 hours. Roaches don’t do “casual visits” the way your cousin does.

Apartment and Multi-Unit Buildings: How to Win When Roaches Have Neighbors

If you live in an apartment, duplex, condo, or townhome, you may be doing everything right and still seeing roaches because they’re traveling through shared walls, plumbing, or hallway gaps.

What helps most in multi-unit situations:

• Seal plumbing penetrations under sinks and behind toilets (big travel highways).
• Bait consistently rather than spraying (baits work in hidden spaces via transfer and feeding).
• Talk to management and request building-wide IPMspot treatments only in your unit can become a never-ending loop.
• Focus on the kitchen and bathroom first (they’re resource hubs).

If you have asthma or allergies, emphasize non-spray approaches and discuss safer IPM options with building management or a licensed professional.

When to Call a Professional Pest Control Company

DIY can work wellespecially if you catch it early and do baiting correctly. But call a pro if:

• You’re seeing roaches during the day (often a sign of heavy infestation)
• You’ve baited and cleaned consistently for 2–3 weeks with little improvement
• You’re in a multi-unit building where reinfestation is constant
• You need targeted treatment in wall voids, crawlspaces, or complex plumbing areas
• You have infants, elderly family members, or severe asthma in the home and want an IPM-focused plan with minimal exposure

What to ask a pro: “Do you use an IPM approach?” “Do you focus on baits and non-repellents for German roaches?” “How do you monitor progress (traps/inspections)?” A good provider will talk strategy, not just products.

Roach Prevention: How to Keep Them From Coming Back

Once you’ve knocked the population down, prevention becomes maintenancenot war.

• Weekly: sweep/vacuum edges, wipe grease, check for leaks, empty trash regularly.
• Monthly: inspect behind appliances, refresh traps if you still monitor, check caulk lines for gaps.
• Seasonally: seal exterior entry points, check weatherstripping, clean garage and storage areas.

If you live in a high-risk building, keeping a few discreet traps under the sink is like having a smoke detector: you hope it stays quiet, but you’re glad it’s there.

FAQ: Fast Answers to Common Roach Questions

How long does it take to get rid of roaches?

Light infestations can improve in days and resolve in 2–3 weeks with consistent baiting and sanitation. Heavy German cockroach infestationsespecially in apartmentsmay take longer and often require follow-up applications and building coordination.

Why do I still see roaches after baiting?

It can be normal to see activity early on. Roaches may come out more as the population shifts. If you see no improvement after consistent baiting, sanitation, and monitoring, rotate bait actives and reassess hiding areas and entry points.

Is boric acid or diatomaceous earth safe?

These products can be lower-risk when used correctly, but “natural” doesn’t mean “harmless.” Follow labels, keep out of reach of children and pets, and apply lightly in hidden areas rather than open surfaces.

What’s the single best product?

For German cockroaches, properly applied gel bait is often the most effective DIY cornerstoneespecially when paired with sanitation, crack sealing, and monitoring traps.

Real-World Experiences (What It Actually Feels Like to Get Rid of Roaches)

I’ve talked to enough homeowners, renters, and “I swear I’m clean!” friends to know roaches don’t just create a pest problemthey create an emotional one. It starts with a sighting. One roach. One single, smug roach that freezes in the light like it’s posing for a school picture. You wonder: “Is this a fluke?” Then you do what every human does in 2025: you Google it, immediately regret the images, and start negotiating with reality.

One common story sounds like this: a person moves into an apartment that looks spotless. Two weeks later, they see a tiny roach near the coffee maker. They panic-clean everything, run the dishwasher like it’s training for a marathon, and spray a citrus-smelling product that promises “kills on contact.” They feel victorious… until they realize the roach population didn’t read the label. The problem gets worse because sprays push roaches deeper into cracks, and the kitchen still has tiny food and water sourceslike the damp sponge by the sink and the crumbs that collect under the toaster.

The turning point usually happens when they switch from “chasing roaches” to “starving roaches.” They stop leaving pet bowls out overnight. They wipe the grease film near the stove knobs (the place nobody thinks about). They pull out the fridge and discover the legendary land of spilled cereal, onion skins, and crumbs that could feed a small country. After a deep clean, they place sticky traps and finally learn where the roaches are traveling. That intel is weirdly empowering. It’s like discovering your enemy’s secret tunnel system.

Then comes the bait phase, which feels almost too simple. Just a few tiny dots in the right places. No fog. No chemical smell. No action-movie soundtrack. But within a few days, trap counts start to drop. The sightings become less frequent. Instead of seeing roaches on the counter at night, they spot one sluggish roach near a cabinet hinge, whichoddlyis progress. It’s not glamorous, but it’s effective.

Another frequent experience: people try a “roach bomb” because it feels decisive. Big button, big cloud, big hope. But later, they still see roachesbecause roaches were hiding where the fog didn’t reach: inside wall voids, behind the dishwasher insulation, under cabinet toe-kicks. The person ends up frustrated and out money. When they finally pivot to gel bait + sanitation, results become measurable. The lesson they share isn’t just “don’t use bombs.” It’s: “Do the boring steps first. They’re boring because they work.”

In single-family homes, people often describe a seasonal pattern. In warm months, American cockroaches may wander in from outdoors, garages, or drainsespecially after rain. The experience there is different: you may not have a breeding population in the kitchen cabinets, but you do have an entry issue. When homeowners seal gaps, address moisture, and place targeted baits or traps in garages and utility rooms, the “random roach sightings” drop fast. It’s less about fighting an indoor colony and more about making your house a bad stop on the roach road trip.

The most relatable thing people say at the end is: “I wish I’d started with traps and bait instead of spraying everything.” Not because sprays never kill anythingthey dobut because the long-term win comes from removing what roaches need and using targeted tools where roaches actually live. When you finally go a full month without a sighting, it’s not just relief. It’s the quiet joy of walking into your kitchen at night without doing the ‘light switch sprint.’
