Ghost--and YELLOW CARDS!

I buy mine on Amazon and clip one to each container. That way, it is easy to identify a "hot plant". IMO, infestation does not instantaneously happen to all the plants at once--rather the little shits migrate from one plant to another. If I can identify and treat the "hot plant" early (the one with the most black dots on the yellow card) then I know in about 14-21 days I will not have another wave of FGs....or at least not as big as what it would have been.

Saponins too...been playing around with strategic yucca saponin treatments and it seems to help. Kinda new idea...

Google: "saponin" "pesticide"

Haven't had em for years in rockwool, hydroton/coco setting;
but just brought in an apparent virulent strain w/ new plants.
Import plants had even been treated w/ Thurgicide liq. & beneficial nematodes a week prior!

Just noticed toast ones inside 1K MH light fixture- theyve been multiplying steadily!

So gonna employ old [ Non- Toxic] multi-pronged strategy:
ReDose all ($eedlings and clones are most susceptible) w/ a Fresh batch of nematodes & Gnatrol granules.
Plus a couple novel devices, i believe made a decisive difference before & haven't heard anyone else reccomend:
Electronic Mosquito zappers!
A tight-grid small unit, hooded to reduce glare, placed under table on nighttime timer, was the set up.
Unfortunately, my prefered Flowtron bk-7 been discontinued for over a decade- apparently a lemon-design. They burnout bulbs prematuely & inner zapper cage plastic breaks down from UVs!
Like mosquitos these gnats are attracted to light and CO2 from the root exhalation, but since much smaller can fly thru big grid yard zappers.
A first gen. Stinger UV vacuum fan model tried had weak pull & only lasted till ~year after warranty motor died & had to add finer screen to catch compartment.
A plug-in nightlight Flea Trap also works good. Enforcer's overpriced and flimsy, but McGuyverable w/ a green Christmas bulb in night light & sticky mouse trap cards from 99c!
Gonna also build one those U-tube sodabottle yeast CO2 mosquito traps' see what i catch:
Get em'

Correction:
Just confirmed it was [b]Microbe-Lift[b] product used initially [Much more than instructed!] , not Thurgicide brand.

Gnatrol.

God I love eBay ignoring Canadian pesticide regulations.

just threw a bunch of cuts and plants out because of gnats, fuck those bastards! tried EVERYTHING to get rid of the fucks but those bitches are resillient as fuck. they will be back dont care what you use, gnatrol, bti, that shit not gonna knock them out if thats what your looking for. i got tired of them and spending shit loads of money on this and that promising to get rid of them. what i personally see is they reproduce too fast for bti to be effective on its own. ive literaly watched dying gnats still try to get their fuck on, dying! they are so preprogrammed to reproduce that thats all the adults know. the plants i ended up keeping still has gnats, they will always be there unless i treat with something that i know i dont want in my garden since i been on this organic shit. so what i did was saturate the pot with a powdered bti product purchased from arbico organics. i then took all pots and placed them inside of some $20 all mesh bubble bags purchased from amazon pack of 8. bought several sets. in my humble opinion this method to me is sure fire nothing can get in or out and pots still receive air, win. i also purchased a product called "mantis" which i highly recommend especially if your battling mites. but i use every where spray under and around every where after youve cleaned and bleached every fucking thing in your garden. plan is to give them nowhere to go and no food to eat. the mantis will knock them flat on their asses with about a 3 hour kill window, and it smells fantastic all organic, the usual oils but i guess they found a winning combination cause it works. its about $60 for 32oz bottle, worth it. but anyways thats my take on gnats do not underestimate them, i just lost some prize plants due to them, they will fuck your roots over, the babies, those are the destroyers, the fucking babies! but im on a rant now gnats have caused me major damage and had to run off.


PEACE!

tried AALLL that, none killed them all, running alone or in combination, slowed, yes, erradicate, no. goal is to get rid of them, contain your pots, then treat better success on plant going full round, when done you can remove entire pot from room with gnats contained, then burn, just kidding, but you just removed gnats, larvae and eggs from your garden,easy.

PEACE!

I say use Diatomaceous Earth..... put a heavy dusting on your top soil, it will kill off knats, the DE cuts thier bodys, i use DE and mosquitoes bits, same company making mosquitoes dunks its a granduler form you can spread out on the top soil. Its toxic to the lil bastards. im knat free with this combo

[mdgg4]

de will do nothing against gnats, gets wet no good. also takes too long to kill the adults 24-48hrs. they will still mate during this time and possibly still lay eggs while dying from de. plus attacking the adults will actually not do anything the larvae is what you need to control. save the de de for the pests running around on the floor, will do shit against gnats. personally i dont recommend against them. DE WILL DO NOTHING AGAINST GNATS

PEACE!

i have a 5 gallon bucket of mosquito bits, they will not completely erradicate gnats, i throw that shit in the pots by the handfull, gnats just dance on top of it. mosquito bits are bti. if you must use bti, for better results run alongside hypoapsis miles, but alone, they multiply too fast. bottom line contain them, cover your pots so they can be completely removed when time comes. if not you will always have a presence of gnats in your garden, you know, that gnat flying around in ya face every now and then.

PEACE!
