Welll there are multiple sub strains of bacillus thuringiensis like B.t. israelensis,I’ve looked into using it outdoors for caterpillars but never tried it inside. If these fungus gnats stay at their current levels I’ll have to try something else, although the DE I sprinkled on the floor of the tent last night seems to have gotten a bunch of them. I’ll buy a couple new sticky traps too when I get the jiffy mix for the grumpz.
B.t. aizawai , B.t. kurstaki And many more the mosquito dunksn active isn’t the same as a caterpillar Bt loook up gnatrol for gnats it’s the same active as mosquitos dunks no extra bs and it’s designed for plants but since I started regularly using nematodes i don’t use but maybe I’ll use one or twice a month as ipm since I have
Bacillus thuringiensis (B.t.) is a naturally-occurring soil bacterium that produces poisons which cause disease in insects. A number of insecticides are based on these toxins (8). B.t. is considered ideal for pest management because of its specificity to pests and because of its lack of toxicity to humans or the natural enemies of many crop pests (14). There are different strains of B.t., each with specific toxicity to particular types of insects: B.t. aizawai (B.t.a.) is used against wax moth larvae in honeycombs; B.t. israelensis (B.t.i.) is effective against mosquitoes, blackflies and some midges; B.t. kurstaki (B.t.k.) controls various types of lepidopterous insects, including the gypsy moth and cabbage looper. A new strain, B.t. san diego, has been found to be effective against certain beetle species and the boll weevil. In order to be effective, B.t. must be eaten by insects in the immature, feeding stage of development referred to as larvae. It is ineffective against adult insects. Monitoring the target insect population before application insures that insects are in the vulnerable larval stage (9). More than 150 insects, mostly lepidopterous larvae, are known to be susceptible in some way to B.t. (5).
