Fox Farms planting mix soil, fungus gnat larve in run off

[basementdwell]

ok well last wk i got ffof and it contained fungus gnats and i knew right away its common so i baked it and pretty sure i got it all out. SO watering my other plants with different soils, i notices some stuff floating in the root resv ?? Strange i never saw it B4 so i took closer look with the 30X scope and noticed they were wiggling and jumping all over but i got a good enough look, fungus gnat larve YUCK, just thinking about them gives me the nebe jebes (Chills) (orry for the mis-spelling). SO right away i call my buddie i got the soil for that pot from and told him to look. Man I hate bugs so i went out today and got Thuricide. I was reading in my book last night that bacillus thuringiensis will kill of the larve and i ve added a layer of perlite on the top of the soil. I have not seen and adults flying around but seen bigger then larve crawing on the surface of the dirt. The thuricide say spray on the leaves top and bottom, Can I use it on the surface of the dirt and perlite ? Can i mix it with my feedings ? I thought benifical bacteria would belong in the soil too ? I need to get some thing into the soil to kill off the larve feeding on the root system

I'm not sure how spray would help eliminate fungas gnat larvae, as they live beneath the soil. I would get some beneficial nematodes to kill the suckers.

well i went for the 2 part attack first i added garden dust to the soils top layer it contains pyretherym. the the thuricide into the watering can but at low levels like 1 tsp per gal then i also did a bath with 1 tsp per 1/4 gal i watered heavily after letting the pot dry for the last 2 days. Then i dunked the roots and lower 1/2 of the pot into the bath for 5 min. I removed and let teh pot dry over night and this am i flushed and have fewer larve in the run off. I am gonna let them dry out again for next two days, but in the mean time i ve added a slice of potato to see if i can attract them to the top where the dust is. Man i ve also found them in my newly passturised soil Man these f-ers are a major pain in the arse, this is war. ? does pyreathern kill benifical beacteria?? I use subcultures in my soil after pasturising ?

I herd bt will kill the larve i havent seen any adults and nothing on the potato yet. I plan to re do the heat process on the soil again possibly transplant the infected ones with new soil and completely clean the roots and maybe another bt bath. i only got to rid the pots of larve, which i read some where the bt will do. I am seeing less of the larve in the runoff. Just cant get over the lady at fox farms telling me these larve and gnats were benifical :rolleyes3fungus gnat larve

Actually a Sierra Natural Science rep just came into the store today, he gave me a sample of SNS-203 it's their new product. Kills root aphids, white flies, thrips, fungas gnats, and their larvae.

Considering SNS is a 420mag sponsor I'd actually get that SNS-203 and try it out.
