The sticky strips have no chemical whatsoever. The color attracts the insects and then the sticky surface "captures" them. Those foggers are made to use inside the house and are tested to be safe with even pets and children, as long as you follow the directions. Of course, you won't be IN the greenhouse when you "fire" one up, and won't return for the period of time that the directions state. There are several foggers that use pyrethrum as their active ingredient. The EPA certifies foggers by the way.
