Frequently asked questions about Wilson FLEA OUT Flea Killer

Wilson FLEA OUT Flea Killer contains 2 modes of action: an instant killer and an insect growth regulator. The instant killer controls insects by direct contact and ingestion The second component, the insect growth regulator, mimics natural insect hormones that stop young insects from maturing into adults. It disturbs egg-laying and egg-hatch and keeps young insects from growing into biting adult forms. This also prevents fleas from multiplying.

Yes, when used as directed. Do not spray people or pets; this product is for bedding, carpets and furniture.

One application of Wilson FLEA OUT Flea Killer kills the adult fleas right away, but it also continuously prevents the emergence of adult fleas from the immature stage for 150 days.

Yes. It has both a quick action and a long-lasting action to control fleas.

It is effective on fleas hidden in carpets, drapes, upholstery, and pet bedding. Leaves no objectionable odour or sticky mess, and does not stain furnishings, if used as directed. There are 4 cycles in a flea’s life: eggs, larvae, pupae and adults. It is important to understand that while an ordinary flea spray may kill existing adults, it may have little effect on some of the other stages already in your house. That is why Wilson FLEA OUT Flea Killer has the added benefit of controlling the next emerging immature flea stage from becoming troublesome egg-laying and biting adult insects.
