Lin from Charleston, Wv writes

Will Onslaught kill flea pupae?

How long will it remain effective against fleas on a concrete basement floor?

Answer:

Onslaught Insecticide is meant to eliminate adult fleas. It is recommended that you use an insect growth regulator, such as Precor IGR, to eliminate the other stages of the fleas. An IGR is a birth control for fleas and will stop them at whatever life stage they are in. It is recommended that you re-treat with Onslaught Insecticide every 10-14 days until you no longer have flea activity.  Please check out our Flea Guide for tips on how to treat and prevent fleas in the future.
