Managing a cockroach infestation can be a challenge. It is important to keep them out of your home. To do this, you should start by conducting an inspection on the exterior of your home. Search for any possible openings or cracks and have them sealed to prevent cockroach entry from the outside. Roaches are attracted to homes because they provide a source of food and water. Be careful about sanitizing your home. Keep the kitchen clean, throw the garbage out regularly and make sure there are no leaking faucets or other sources of standing water – this includes pet bowls. You should also keep trees trimmed, which helps prevent branches from becoming access points to your house. Another helpful trick is to change outdoor lighting to the yellow "bug" lights, which will reduce their draw for insects.
