Ok all y'all Ladies that live in the south. How do y'all keep the cockroaches away. I've been trying so hard to keep them out of my house but it's not work. Just bought more combat. It seems to be working but when money gets tight again I only buy what we need and combat is not one of them so what are some tricks and cheap and easy ways to keep the cockroaches away. Please don't judge me my house is clean it's just hard to keep them away especially living in Arkansas
