Is this the same Bt that is used to kill caterpillars?

Mosquito dunks are the shit. I have been using them for years with great success. Glad to see others utilizing this simple yet extremely effective means of getting rid of root gnats for good! Peace and happy hunting to all.

No BTI is not the same one used to kill catepillars.
That would be BTK the "kurstaki" variant

Hey, could someone confirm that these are fungus gnats for me? I just transplanted 10 seedlings into this dollar general potting soil and when I moved them under the light I seen the soil just explode with little fruit fly like these flying all over.

Heres the best pictures I could get of one:





I'm going to try to get to the store tomorrow to find some mosquito dunks, but I might not be able to until monday. Could I get some reassurance that they aren't going to kill my seedlings in three days?

thanks

No, they won't kill them in three days, an yes that looks like a fungus gnat to me.

I tried some Dollar general potting soil last year...yuck.

If you have a small batch of babies, I would put them overnite in a plastic tote overnite with a Shell No Pest strip. This will knock out the adults, give you a little room to tackle the grub stage in the dirt with the dunks.

good luck!

Maybe I'm just lucky...

or maybe it's the fact you ebb n flow, mine's constantly submerged. The exposure to air for even a little while may allow the gnats breeding time on your roots. The eggs or larvae must be falling into your water somehow. My understanding from the literature is that the gnats lay eggs on the leaves(not breed in water as you say) and the larvae hatch, fall to the ground, and burrow in. Sorry you have this battle on your hands. Mine's history.

k33ftr33: Thanks for posting your positive experiences in hydro with dunks. I would think that is where dunks would shine, as they are intended to be chunked into ponds.

that thing looks like a mosquito or something. is the pic magnified? how big is the thing? fungus gnats are the size of ants w wings. they fly in-out of the medium & eat your roots.
