I have many animals and I don't want to harm them with chemicals. I sprayed raid in the area I noticed the ants coming in and that was after I had moved my birds and hamster to a safe location. I noticed only a few ants after that and now they're all back. What can I do? I've tried lots of stuff. I want something that won't harm my animals. I've tried raid, vinegar, cayenne pepper, black pepper, soapy water, and grits and none have worked. The raid did kill the ants but now more are back. Please help. Thank you.
