I just despised any critters that move with me. I don't care how hot it is outside. My house my rule! My apartment was over run with fleas (from girls) they like to roll in the grass when they are outside playing. It's a joy to watch them have fun. The little beasts the carry inside not so cute. Then I have roaches to contend it. My Flea Sticky Trap works great for both but I needed backup after my apartment was professionally fulmugated. Yep I have peace of mind for now. Each room has a Ultrsonic Pest repellent with Night Light Lamp and the Sticky Trap just in case.
