Flea control

I have a dog, I flea treated him but my room mate had cats that she did not treat. The infestation is bad. The room mate has since left with the cats, but my house is still infested. I never had this problem before until her cats arrived. I’m overwhelmed and don’t know what to do. Also do not own a working vacuum. Hamilton, Ontario

You should consult with a licensed veterinarian for specific advice. Click here This site has some general recommendations that may be helpful.   I also highly recommend you obtain a good vacuum cleaner.
