Will Talstar PL Granules harm earth worms?

I need to control fleas, ticks, pine bark beetles, etc.


Talstar PL Granules are not labeled for earthworms. Earthworms are highly beneficial creatures and you will not find a product on the market that is labeled to eliminate them. Talstar PL Granules are labeled for fleas and ticks and not pine bark beetles. Since pine borers are a type of bark beetle you must apply a product directly to the bark to control the beetles and these products are only available in liquid form, Talstar P. 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. Healthy trees can be protected before the beetles attack by topically spraying them with a synthetic pyrethroid like Talstar. The tree should be sprayed from the ground to 15 ft up the trunk to prevent future infestations. You should contact your local cooperative extension office to find out the best time to start spraying in your region.
