No Pest strips are easy to use for plant pest. It contains an organophosphate like Vapona, so don't handle the strip. "It is effective against mushroom flies, aphids, spider mites, caterpillars, thrips, and whiteflies in greenhouse, outdoor fruit, and vegetable crops. It is also used in the milling and grain handling industries."Wiki If you have a bad plant you can shut it up with the strip in a shed or trash bag overnight.
When I have a problem in the GH, I use a Hot Shot Fogger. They have a synthetic pyrethrin, which has a very, very low LD50, or mammal tox factor.Safe for pets, etc. You do need to turn off any ignition sources, propellent is isobutane and very flammable. I corresponded with the company and it is an acceptable use. 1 "bomb" will treat a 10x12' room or in this case GH. I have seen no ill effects to the plants and I have some sensitive ferns, orchids and tropicals.
