In theory, yes, but personally I don't like to add oily substances to the soil. Some people have perfectly decent results though so I'd google your subject for dosages.
If you have fungus gnats, the best way to deal with them is to start by finding where they live. Look under pots and in drip trays for standing water or soggy soil. Get rid of it- even if you have to put your plants up on racks, any standing water means breeding grounds for pests and disease.
Next, look into a pyrethrin bomb to kill exposed insects in your grow room. 2 bombs set off 3-5 days apart, plus removal of all your yucky wet areas, should completely solve your problem.

the sticky yellow things work fairly well for catching gnats flying around. you could also try a no pest strip. i found out about those from this site (iforgot from who sorry). you just hang it and there shouldnt be any more bugs in the room.

I fought fungus gnats about a year ago. After trying the usual solutions without success I bought some Pyrthren(sp) concentrate. Added 30ml per gallon and applied once a week for 3 weeks. Haven't seen any since. I also use the the spray cans designed for automated application to spray my room regularly. About 10 'puffs' of this fills my room.

BTW, if you're worried about the dosage, don't. My plants acted quite normal when receiving this dosage.

hey stinky, would a "pyrethrin bomb" work for spiders.
i havent seen any, but in a recent pic i can clearly see a spider web all up on one of nugs.
i dont really want to use need oil.
would that bomb work?

thanks for all the replies friends...

but are there any recommendations for a soil drench?

my plants seem to be mature enough where the plants are fine....its the soil and roots that I'm worried about since that's where they lay their larvae


thanks again

I'd like to know about the soil drenching as well.......

Ooooo those godamn mother$#@*&%$! GNATS!

I feel your pain, had quite a case of them on my last "attempt." Infuriating little bassids... The cure that finally worked for me was the bright yellow sticky traps I got from eco in conjunction with FoxFarm's Don'tBugMe spray. I'd dose the top of the soil as well as the bottom of the pots, where the drain off holes are. If the problem is really bad, a bomb like stinky mentioned might be more in order.

I've found you can increase your odds of avoiding them by not using manure based compost in your soil mix. Eggs can survive the bovine intestinal track, as well as the subsequent curing and packaging of the compost. This time around I used only ProMix for my potting needs, and have yet to see any kind of pest near my *knocks on wood* girls.

Roots are funny things, I'd be careful with unconventional tactics, particularly if you're well into a grow and nearing harvest.

Hanayama-san,

Since you mentioned a web, it seems you aren't talking about spider mites. Not sure if actual spiders are cause to worry. I'm fairly sure they don't screw with mary, and I've heard they're good for gardens as the prey on other creepy crawlies. Due to their sensitive physiology they are a metric on the presence of pesticides and other chemicals.

And for the record, I'm pretty sure pyrethrin works on all insects, beneficial varieties like ladybugs and spiders included.


Ganbatte-kudasai! :thumbsup:
