Best Roach Sprays

9 minutes to read | Updated for 2018

Roaches are among the most adaptable creatures on the planet. Additionally, these critters are linked with several diseases and the rapid spread of germs. Dealing with a roach infestation can not only cause you to cringe but can also frustrating and difficult to deal with as roaches are excellent at hiding.

Cockroaches usually hide during the day in cracks and crevices in walls, along with door frames, and in secure places such as cupboards linings, basements, electrical devices, and breaks in building foundations. This tendency to hide in small areas is part of what makes roach killer sprays such a useful product.

When bait stations, gels, or powders alone are not working, using a roach spray can help rid you of your pest problem. With all of the products below, we recommend using gloves to protect your hands when you apply them and take precautions to avoid inhaling any sprays.

A fantastic option for those worried about harsh chemicals or as a supplemental product to other roach killer products.
Ideal for the hardest to reach areas that might have larger roach hiding spots. Expanding foam can treat open areas that are blocked off with only thin opening.
Perfect for those with either a lot of hairline cracks or gaps in cupboards or baseboards that insects could escape into, as pin-point spray targets cracks.
EPA approved, safe for homes with pets once it dries, and lasts up to 12 months. Sizeable one-gallon size will cover a lot of ground both inside and around the foundation of your home.
