Diatomaceous earth will get rid of them. PLUS it’s good for all plants,trees etc. Kills fleas, ticks, internal worms.
Yes. Diatomaceous earth is good, but be careful to NOT get it in your eyes. It is sharp little critter skeletons that can cut the eyeball; so wash your hands after handling it and keep it away from children.
I put it in jar lids and hide them under furniture where no one can get to them. Bugs crawl into the lid and get cut up and killed by the shards. (I also add a little bit of powdered sugar to the diatomaceous earth and I think it further attracts bugs.) It also lasts forever unlike those little expensive roach hotels. - I’ve even dusted it along under the carpet along the floor trim in my rooms where bugs crawl along. We have been in this house for almost 23 yrs. and have no bug problem of any sort, and without ever having to call the Orkin man.
BTTT for diotamaceous earth. Might be hard to fog the tree tops though...
