Did you turn on your kitchen light and catch sight of some roaches skittering away? Even if you manage to squish a few, there may be more you haven’t seen yet. The thought of cockroaches hiding in your home may be unpleasant, but you can easily get control over these pests before they start to spread. Keep reading, and we’ll walk you through how to trap, kill, and prevent those pesky roaches from growing into an infestation.

This article is based on an interview with our MMPC-certified pest control specialist, Kevin Carrillo. Check out the full interview here.

Things You Should Know

  • Put adhesive traps in cabinets, under large appliances, and in the corners of a room to stop cockroaches in their tracks.
  • Leave out bait traps so roaches bring pesticides back to the nest to kill the entire infestation.
  • Spray roaches with insecticide or a concentrated liquid roach killer to kill them on contact and deter them from the area.
  • ​​Try dusting diatomaceous earth or boric acid along cracks and crevices to use them as natural pesticide powders.

    The food in bait stations contains pesticides that slowly kill roaches. Place the bait in an area where you know cockroaches will encounter it, such as along baseboards, under the sink, and in corners. [1] When the roaches eat the poisoned bait, they’ll bring it back to the nest to help get rid of the infestation . [2]
    • Bait stations may take several weeks to kill all of the cockroaches since their eggs could hatch after you get rid of them.
    • Alternatively, look for gel baits that you can apply under the lip of your counter or hinges of your cabinets. [3]

    Using liquid roach killer helps you control the toughest infestations. Follow the exact mixing instructions on the pesticide to dilute it properly since they may vary between brands. Once it’s mixed, use an aerosol sprayer or a mop to apply a thin layer onto the surfaces where you’ve seen the most roaches. [4] Focus on cracks or crevices around your cabinets, spaces under large appliances, and the edges of your basement. [5]
    • Keep pets and children away from any areas where you apply pesticides since they can be toxic.
    • Concentrates can be particularly effective at preventing reinfestation since they usually deter roaches for 1-2 weeks or more.

    Get rid of roaches you see with a quick spritz of insecticide . Use a spray specifically labeled for roaches since it will be the most effective. Whenever you see a roach, take out the insecticide and spray it directly on the bug to kill it. Apply the spray on cracks and crevices and along baseboards so any roach that walks through the area gets coated in the insecticide and dies. [6]
    • Follow all safety instructions on the product's label since they may vary between brands.
    • If you don’t have any spray on hand, try misting the cockroaches with rubbing alcohol to kill them. [7]
    • Since insecticides use chemicals, keep pets and children away from the areas you’ve treated.

    Cockroaches will get stuck as soon as they go in the adhesive traps . Set the traps wherever you’ve seen cockroaches, such as in your cabinets, under your sinks, or along the baseboards near entryways. [8] Put the traps in each corner of the room and leave them out for 2–3 days before replacing them. [9]
    • In a pinch, make your own sticky traps by wrapping a piece of cardboard in duct tape so the adhesive is facing out.
    • Keep track of how many cockroaches you catch on each trap so you can see what areas in your home have the biggest pest problems.

    Cockroaches get dehydrated when they walk through diatomaceous earth . Use a bulb syringe to spread the diatomaceous earth. Apply a thin layer that’s barely visible around cracks and crevices so cockroaches have to walk through it. Try spreading it in other places too, such as underneath your sinks, along baseboards, and inside cabinets. [10]
    • Keep diatomaceous earth away from pets and other people since prolonged exposure could cause lung irritation. [11]

    Look for thyme oil , clove bud oil , or citronella oil since they’re the most effective at getting rid of young cockroaches. Spray the essential oil directly on the cockroaches when you see them. Otherwise, just spread the oil around the baseboards where you’ve seen cockroaches most frequently to keep them away. [12]
    • Reapply essential oils once a week so they stay effective against roaches.

    Boric acid causes the roaches in your home to starve. Dust a thin layer of the boric acid powder into the cracks around cabinets and baseboards. Leave the boric acid for about 1 week before vacuuming it up and replacing it. [13]
    • To attract more roaches to the boric acid, mix in 1 part powdered sugar or flour. Roaches will be drawn to the food source so they’re more likely to ingest the boric acid.
    • Boric acid isn’t highly toxic to humans and pets, but try to use it only where the roaches will get to it to prevent exposure.
    • Avoid using boric acid outside since it’s toxic to plants.
    • Some people claim to kill roaches with baking soda, or by mixing baking soda and boric acid, but baking soda isn't an effective insecticide. [14]

    Rather than leaving food out in the open in your kitchen, store it in your fridge or airtight containers. Wipe up any food scraps and crumbs left on your countertops or stove so the roaches don’t come back. [16]
    • If you have a pet, check that their food is sealed and stored too so the roaches don’t get to it.

    Keep your trash in a can with a lid so cockroaches can’t get to the food scraps inside. Try to take out the trash as soon as it’s full, or after a couple of days so it doesn’t spoil or attract any bugs. Tie up the trash bag and toss it in a receptacle that’s sealed and away from your home. [19]
    • Avoid storing lots of cardboard boxes near your trash can since they make perfect hiding spots for roaches.

    Take a little bit of time throughout the week to clean up so you can keep the cockroaches away. Start in the kitchen by washing your dishes and putting away leftover food promptly. Sweep your floors to clean up crumbs on your floor, and mop them thoroughly to get rid of any residue that’s built up. [20]
    • Put things away in their proper places rather than leaving clutter since roaches could find new places to hide.

    Cockroaches are absolute experts when it comes to hitching a ride into your home. Cockroaches can sneak in from a delivery package, the cardboard cutout for a 6-pack of beer, or airport luggage. Once they're inside, they're there for good and it can be pretty difficult to get rid of them.

    Cockroaches like to hide in small openings that are only 1 or 2 millimeters wider than they are. You can find them at the top of cabinets, behind shelfs, in small openings around baseboards, and behind appliances. This is part of why they're a pain to get rid of; it can be hard to find where the cockroach's nest is.

    Yes, the over the counter baits and sprays will kill cockroaches. You can always spray them with rubbing alcohol, too. That will kill them pretty quickly.

      Tips from our Readers

      The advice in this section is based on the lived experiences of wikiHow readers like you. If you have a helpful tip you’d like to share on wikiHow, please submit it in the field below.
      • If you stay in a motel or other location with a roach problem, be extra cautious not to transfer roaches back home with you. Carefully inspect luggage before packing it and wash all clothing immediately when you return. Store food tightly sealed and keep your space very clean.
      • When spraying pesticides into cracks and crevices, spray until soaked to ensure roaches contacting the surfaces die quickly. However, avoid overusing pesticides and don't continue using them unnecessarily once the infestation is under control.
      • When using boric acid powder or other pesticide dusts, be sure to wear gloves while applying it. Then discard the gloves so roaches aren't attracted to pesticide residue on your hands later. This protects you from exposure.
      • Consider adopting a few geckos and releasing them in your home. Geckos will hunt down roach nests and eat their eggs. This can provide natural pest control. However, be prepared to be startled by the freely roaming geckos!
      • To make a homemade sticky trap, cover a cookie sheet completely with shipping tape, sticky side up. Put sugar or another food in the center as bait. Roaches will be drawn in and get trapped by the tape.

      About This Article

      Article Summary X

      To get rid of roaches, keep your kitchen as clean as possible to cut off their food source. Wash dirty dishes right after using them, wipe the floors and countertops regularly to get rid of crumbs, and clean up spilled food in your kitchen cabinets. Keep your trash in a sealed bin so roaches can’t get into it. Additionally, make your own cockroach bait by mixing 3 parts boric acid with 1 part powdered sugar. Sprinkle the bait in your kitchen cabinets, behind appliances, and in your pantry. The sugar will attract roaches, and when they eat it, the boric acid will kill them. Make sure to keep children and pets away from your cockroach bait. If you encounter a roach while you’re cleaning or putting out bait, spray it with soapy water to kill it. Keep in mind that it can take weeks or months to get rid of all the roaches in your home, so you may want to hire an exterminator if you can’t wait that long. To learn more about how to set roach traps and use pesticides, continue reading!
