I have stray cats living underneath the house and can’t get rid of them. Clearly, they have brought a flea infestation with them. I found a flea in my bed last night and am really freaked out. I sprayed last week and don’t know why I can’t get rid of them with hardwood floors and no pets. Do you have any suggestions? Do they live on the bed? How are they getting onto the bed? I thought they could only jump ankle high.
