Help! Pests in Terrariums.
I have a couple terrariums in 30 gallon aquariums. The bottom has sand and about 5 inches of water with guppie fish in them. Hanging on the sides and all over are my miniature mounted orchid collection. Problem is I have low levels of pests in the system and cannot spray pyrethrins (which I normaly might) since it is very toxic to fish. The pests include aphids, meallybugs, snails, scales and miscellaeous bugs (from who knows where - some of my orchids are from far away places).
My question is what pesticide is there that kills bugs but not fish?
Soapy water? (I think it would affect fish)
Anybody have a pond with fish that they spray the edges for pests at?
Anybody have a terrarium that they want to contrl the bugs in?
Remember, the limiting factor is fish are an integral part of the ecosystem.
