Thank goodness we never had bedbugs but had a problem with fleas coming from a neighbors house that had 3 cats that ended up with 8-9 after kittens. We didn't even have a pet! These work but you have to redo it several times because of the lifecycle of a flea. I am allerigic to them (the saliva really) so was quite frustrating and if you are as well you need to know that even when you can go back in your home they will be dying still and will bite even harder and more for a day or two. You need to do it at least once a week until they are all gone, can't speak for bedbugs though. I did find a spray I liked better because you could spray under furniture and the furniture itself and only have to be gone until it dried, about two hours rather than 4 or more.
