Jeffrey from Joelton, Tenn. writes

Will Onsalught stain cloth couches, chairs and drapes etc, if fan sprayed?

Could Onslaught be used as a fan spray for fleas indoors. And how is the odor of the product. Thanks Jeff.


Onslaught is not labeled for use on furniture so we would recommend avoiding contact with couches, chairs and drapes.  You use on carpets as directed on the product label.  Onslaught is odorless.

Or we recommend that you use Ultracide for the indoor treatment as it can be used on all carpeted areas, pet bedding and upholstered furniture. Ultracide Spray contains Permethrin and Phenothrin to kill adult fleas fast. It also contains Methoprene (an insect growth regulator) to prevent reinfestation for up to seven months. Methoprene penetrates deep into the base of carpet and upholstery fibers, where pre-adult fleas live, and targets fleas in the egg and larval stages of development, preventing them from producing new infestations of breeding, biting adults. Be sure to thoroughly vacuum immediately before the treatment and every day for the next 14 days to help speed up flea elimination.
