Use boric acid

Boric acid has proven to be an effective countermeasure against cockroaches. While boric acid is not the silver bullet to get rid of cockroaches, it does kill the roaches. By tracking the cockroaches’ movements, you can find the right spots to lay down the boric acid so that the roaches walk through it. The roaches will not realize what they are doing as they walk through the odorless spray. Although boric acid is not dangerous to pets, you need to be sure you keep it away from your eyes, mouth, and places where food is made.

Use diatomaceous earth

Diatomaceous earth is another pet-friendly solution to stop cockroaches. Diatomaceous earth pierces the cockroaches’ exoskeleton. In order to effectively use diatomaceous earth, you must dry any damp areas as diatomaceous earth will not work when wet. Then, apply diatomaceous earth everywhere you have seen cockroaches, around the foundation of the home, and in a crawl space if it is not used for storage. From there, just keep reapplying if the DA gets washed away.

How to prevent cockroach infestations

Now that you have eliminated the current roach problem, it is time to prevent any future cockroach infestations. This will ensure that you don’t have any future problems with roaches and you do not have to kill them again.

  1. Keep the home clean – this was also the first step in getting rid of roaches, but the best way to prevent a future infestation is denying the roaches a good place for them to live. Make sure you clean up all crumbs, clean grease off of surfaces, and take out the trash regularly.
  2. Eliminate outdoor hiding places – sometimes, cockroaches will find a nice place to live outdoors but will move indoors once it gets colder. To avoid this, make sure that your yard does not give them a place to live. Make sure to clean up leaves, other yard debris, and check any piles of wood you might have around the house.
  3. Eliminate entry points – roaches have to get into your house from somewhere. Look inside and outside your house for cracks to seal. Good places to make sure to check are cabinets, moldings, and pipes.
  4. Use preventative products – find potential entry points and prevent roaches from making it through. You can use essential oils, traps, or preventative sprays.


Having a roach infestation is one of the least enjoyable things that can happen to you. However, you can get rid of cockroaches using one of the methods outlined above. The best way to get rid of cockroaches is to prevent them from entering your home in the future. If you do not have an infestation today, please follow our preventative steps to make sure you never do.
