Unknown bugs infestation

I am having a problem identifying a bug that is eating my crops. It is about 3mm long, black with beetle like plates to protect its wings and a back-end that it can raise up like a rove beetle. It flies like fungus gnats but in soil it moves fast like a predator. This is the only bugs that I can see and they are causing yellow fan and stunted growth. Too fast for me to get a pic. Any ideas? They almost look like a Devil's coach horse beetle but without the big pincers.

Get yourself an organic pesticide.

You need HOTSHOT No Pest Strips. That is your only hope! I have no bugs in my grow because of them.

could they be thrips?

don't get no pest strips btw. thats way over kill and only a last resort to save unique genetic mother plants in veg phase. only usable if you don't ive in the same air.

if you have thrips some captain jacks dead bug, or some other bio product containing spinosad will take care of them.

Do they hop? It sounds like root aphids.

Get a white bowl or container like for sour cream or cottage cheese. Fill it half way up with water and place it under the light so the light hits the water. The bug will be attracted to the dish and fall into the water. When it drowns you can scoop it to see what it is.

I've caught them in a yellow sticky and they look like fungus gnats, however, mosquito dunks don't work on them, spinosad only gets a few flyers and a spinosad root drench did nothing but almost kill my plants.
They are not root aphids as they are black and slender with a tail that it can raise like a scorpion and they are fast. Watched one run across the soil and then take off and fly around the pot. I thought they were rove beetles, but they fly.

Dust your medium with grounded cinnamon for larvae,and for flyers use yellow sticky
traps.. cinnamon kills larva much faster then Bti..

NO PEST STRIPS!!! It is your only hope! Just do not stay too long in your grow room. Do what is important and then get out.
