i have root aphids and have no clue in getting rid of them

i am in my second 2-3 week of flowering and have a bad root aphid promblem .... i also have a nat promblem as well . i tried azamax and used a pyrithym bomb to kill them . most of them died but i still see a few of them crawling around the grow cubes ... i am wondering if anyone knows a way to eliminate them once and for all

THANKS >>>

From the other r.a. thread:

I've had good success controlling them with Azamax, but recently my mom looked like she might be fucked. After the second soil drench, they were still coming out the bottom of the felt pot. I kept them from spreading by putting duct tape around the perimeter of the saucer. I almost cloned her out in fear of the winged version appearing, but instead I asked the guys at the grow shop for advice. They sold me this stuff called evergreen, a pyrethrum concentrate. I drenched last night, and as this morning I haven't seen a single aphid.

Figured I would share because in all my research into root aphids, I had never heard of this product until yesterday. Glad I went with this instead of bayer advanced, or SNS 203.

I actually had a really bad root aphid problem too!! I found a post that said to use some Bayer insectide at mild dose and it worked great!!! However, this was during the Veg phase.

I also had some decent results with Fox Farms bug off pest control which uses Pyrethrum. However, need to spray directly on the problem!

worst bug ever!!!!

if you are only in week 3, chuck them and start over. sterlize everything
one you start seeing the winged stage, they have already colonized your pots and are looking for a new home.
they mulitply fast.....like each one has 6-8 live pregnant young every 6 days.

if you REALLY need to keep them, it could get expensive. but i did it and had a half yield. (your buds will also not get dense, but gravity and silica will help)
here is what i did at week 5 when i found out i was dealing with RA and not Fungus gnats.

Mighty wash dunk/drench everything
no pest strips will kill the flyers in 24h. just make sure you rinse the leaves off really well afterword
MET 52. there are threads about this on thc farmer. its a fungus that grows in the soil and kills on contact. the problem is you already have roots and it takes 2 weeks to innoculate. and you need to spread them out.

other things i hear help are nemitodes, but not 100%
liquid pyrethum (pyganic, evergreen) people say are working good. drench the soil.

if you wanna go chem you can use avid, bayer treen and shrub. but i wouldnt.

ohh and STOP BUYING CLONES FROM DISPENSARIES (this is how everyone is getting them)
 
Powdery, mites, botrytis....I have no problem. Root Aphids are the worst; they sneak up on you and ruin your garden. I have had these little fuckers pop up every year or so. Typically some sort of new cloned genetic or cross contamination from a harvested pot/plumbing gets into a freshly flipped pot. I grow hydroponic SOG with felt pots 9 roots per light and Deep Water SCROGwith 4 per light.

One Solution that has been used/recommended that should never be used:
Bayer 3 in 1 used 30 days from harvest: Imidacloprid, Tau-Flavalinate, and Tebucanazole are the active ingredients. Imadicloprid is a synthetic nicotine product and is systemic. It is toxic to mammals, fish, and insects. It is nasty stuff. It is debatable whether it is safe to use on anything other than mothers a generation removed from anything that will be smoked. Tau-Flavalinate is a synthetic pyrethroid and kills SOME aphids on contact. Tebucanazole should never be used on anything that is going to be smoked.

Things you can use that will kill some aphids, but will inevitably leave a resistant population that will re-infect your garden are Neem Oil Extracts, Pytheum products, and other oils (cinnamon, etc.). The aphid life cycle is multi-stage and these products leave a percentage of bugs every time. The next time the population takes off, you're fucked.

GoGnats will slow things down, but the aphids will still fuck your plants.

The only way I have found to save your genetics and not risk poisoning someone is too kill everything except your mothers, use a .0015% imidacloprid ONLY drench/dip/flush on the moms(Bayer Fruit, Citrus, and Vegetables(.235%) or Ortho Max(1.47%) dilute appropriately.) I will let everything dry out as much as possible before the application to ensure that the imidacloprid is absorbed into the media/root ball. If I'm flushing a deepwater system, I only run it for 10 hours during the light cycle and the flush the system.The mom is inoculated, and I have never had problems with any imidacloprid treated plants again.

Sorry there isn't a better solution. I wish I knew the safe interval between treatment and harvest for cannabis using imidacloprid. If I was confident it was safe, I would use it in veg as part of the standard regimen.

neem oil if there are no buds then spray plant and then do a root drench. put a layer of sand, i do 1" this will keep adults from laying offspring in soil and prevent the larve from becoming adults because they cant burrow up thru the sand. do the neem every 4 days for three treatments that should cover an entire life cycle. i use sand now wether i see gnats or not.

neem oil and azamax won't kill them off. It even says on the box that it is only used to control the population, not kill them off. Sand will help, but if you are using any pots with holes on the bottom, it won't work. They'll just crawl out the bottom. I've used imid before in veg. Works , and no ill health effects.

if you're in flower, use evergreen. If that doesn't work then toss them and sterilize
