Permethrin SFR 36.8% - Questions & Answers

For flea control, we recommend retreatment with insecticides such as Permethrin SFR every 14 days until you have no more signs of fleas. Most successful flea treatment programs require at least 2-3 treatments at 14-day intervals using both an insecticide for the adult fleas and an Insect Growth Regulator (IGR) to prevent immature stages of fleas from developing into breeding adults. You will not be able to make just one insecticide application for fleas and never see them again, especially if you did not use an IGR in your treatment. Fleas multiply very quickly, and they have an immature stage that is protected from insecticide, so new fleas will continue to emerge after you have treated. Be sure, also, that you are vacuuming every day or every other day to help pick up adult fleas, flea dirt, and eggs, and also to stimulate those immature fleas so the adults will emerge and be exposed to the insecticide you have put down. We have more tips and details in our Flea Treatment Guide here.

Healthy trees can be protected before the beetles attack by topically spraying them with a product called Permethrin SFR. The tree should be sprayed from the ground to 15 ft up the trunk to prevent future infestations.  Unfortunately, there is no easy solution when it comes to pine beetles. Infected trees should be cut down (before the newly hatched beetles fly out of the trees in the spring/summer) and the wood burned or chipped, while other still healthy trees should be sprayed annually to protect them. Because of the natural boring behavior of the beetle they are protected from topically applied insecticides and systemic insecticides (those injected into the tree or applied as a root drench) have proven ineffective for pine beetle infestations.
