Stubborn ass fungus gnats

So I’m still battling a fungus gnat issue. Took some pics for a verification, but I’m 99% certain these are fungus gnats.
Anyway, hit them with Spinosad (Monterey’s) prolly 5-6 times by now, each application about 3 days apart, but the fuckers are still here.
Should I up the amount of Monterey’s I dilute? As of now just using 2 tsp per 24oz of water.
I’m about 9 weeks into flower and never see them flying, only show up on my sticky pads.
Any suggestions here?

You need to kill the grubs with Bti, and keep applying it during a grow.
The flyers can go around the house for weeks, break the cycle

I don't have time to see what Spinosad is listed for. What are your application rates and how are you applying it?

Yes, looks like fungus gnats. You've got to break their life cycle. The adults aren't damaging. They're more of an annoyance. The larvae are damaging to the roots. To control the larvae, and break the cycle of going from larvae to adult, I use Monterey BT in soil drench. Also, I sprinkle Mosquito Bits on the soil. You can also use crushed mosquito dunks on/in the soil. That will control the larvae pretty quickly.

To prevent the adults from laying more eggs in the soil, you can put a 2cm layer of playground sand on top of soil.

You can prob get the dunks, and maybe the bits, at Home Depot or another hardware store.

I use the Montetey BT with sprayer attached because the bottle is cheaper per volume on Amazon. Same stuff inside, just take off sprayer and make your own mix.

"Hot shot" no pest strips.... they will annihilate them in 2 to 3 days... then get them back in a sealed bag triple wrap them and keep em for next time.

Stay away from them and handle in ventilation. That shitnis nasty but the only thing I found that works with those little bustards!

Just double the spinosad and spray the soil daily.. 1tbs per 24oz.
Don't use no pest strips in your grow.. Poison!!

Thank you for making that clear. I was not aware of the differences in the subspecies.

Was applying every 3 days, spray top layer of soil until wet all around 2 tsp>24oz of water.
I’m not really seeing any damage they may be causing, I’m more concerned with em stuck in my buds in the end

I have stopped seeing them after I stopped keeping the soil so moist and use Timothy hay to cover soil
