If I put blankets and sheets and clothes outside when it is below freezing will it kill the fleas and there eggs and larvae?
Yes and no. Yes, freezing temps will kill both adult and larvae fleas that might be on the fabric if you keep it outside for 24 hours. But as our FLEA CONTROL ARTICLE explains, the adults and larvae are really only 25-40% of the problem. If you currently have a flea infestation, the only way to get rid of them will be to employ one of the control methods we have listed in our article. And this will have to be done where the fleas are laying their eggs which is usually inside the home or on the resident pet.
