I have a flea infestation! I got rid of my cats, but can’t get rid of the bugs. I thought I had most of them, but it seems that new ones have hatched(they are much smaller than the first round). I vacuum and I sprayed the furniture with an IGR insecticide. I am pregnant and don’t want to use too many chemicals in the house, but I have to get rid of the fleas. It seems we have more now than when I started. I bought one of the flea traps with the light and glue pad and that works well, but it is very localized, it doesn’t get them all. Can fleas breed if there are no animals in the house? I read that they lay eggs after a blood meal, does that mean human blood? I haven’t noticed them biting too much, though. Any suggestions? Any help is greatly appreciated!
