Has anyone used MOP UP Boric Acid to kill fleas (cat)?
MOP UP is not a product that you should use for treatment of fleas. It does not contain an IGR (insect growth regulator) which is an important part of any flea treatment. We would recommned our indoor flea kit which has a very high success rate and contains flea specific products with an IGR.
