Best Roach Sprays
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.

Advice and Precautions for Dealing with Cockroach Infestations
Regardless of the product you use, if you are trying to remove cockroach infestation, you need to clean up any beverage spills and food crumbs right away so that sustenance is not readily available for the roaches. Always read directions and warnings on labels before use. You may need to try more than one method if you have a severe infestation or have never dealt with cockroaches before.
Use Caution
Do not let children or pets near any spray until it is thoroughly dried. We recommend using gloves and even dust and fume filter masks and safety goggles while using sprays. Do not mix chemicals, as many can cause fumes that are toxic to humans.
Allow any spray you use to dry completely before applying another type of roach repellant in your house. Do not apply poisons in vents where the chemicals can be blown through the air in your house or apartment and cause respiratory distress.
Avoid Attracting Further Pests
Roaches are attracted to food and water sources in homes, and warmth in more temperate climates. Keeping your house as clean, sanitized, and moisture-free as possible is essential to avoid attracting roaches. Remember, cockroaches are small, even if they seem large at two inches. So, it only takes a little bit of food or moisture for them to find enough water to survive.
Keep Your Food Away from Poison and Roaches
As always, use caution when applying this roach killer near your own food sources and package any consumables in bags, plastic, or glass containers to protect your food from coming into direct contact with the gel. Packing all of your food in plastic or glass containers to prevent roaches from getting into them is another measure you can take to keep them from finding nourishment in your kitchen.
Remember fruit trees if you have any right next to your house, too. Fallen fruit on the ground should be cleaned up as much as possible. It might seem extreme, but the more you can limit supplying roaches with nourishment, the less reason they will have to move in. With any product you select, if you are trying to remove cockroach infestation, you need to clean up right away so that food is not readily available for the roaches.
Take Care of Moisture
Roaches are also attracted to moisture in houses and apartments. If you live in a humid setting, invest in a dehumidifier and dump the bucket often. Using a dehumidifier in your basement, or even in the central part of your house or apartment is a good idea especially if you live in a high-humidity area.
Think about all areas of water sources cockroaches could get to such as pet water dishes, condensation on toilets, dripping faucets, and water left on the floor after exiting a shower could all attract roaches. Wiping away water anywhere you find it and making dishes harder for cockroaches to reach can help.
Use a Few Methods If You Have a Tricky Infestation
While you never want to mix two types of poisons together, you can consider two methods of pest control if you have an excessive number of roaches. Some people have a professional come in and bug-bomb their home, then follow up with their own bait to prevent cockroaches from returning. However, relying on one product might not work well if you have a heavy infestation.
Make sure areas are well-ventilated when using sprays. One option is to try a sprayer, allow it to dry thoroughly, and then also set up a few roach bait stations as an additional measure.
