Hi Steve,
I have found that sprays containing pyrethrins are very hard if not fatal to
Drosera's. My VFT's and Nep's don't seem to mind pyrethrin. I keep my
plants in aquariums and I find that a flee collar a piece of a "No Pest
Strip" next to the plants keep the bugs at bay. If you grow in a greenhouse
these probably wouldn't be very effective.
Good Growing,
John in Phoenix
