Spiders and fungus gnats...

[blondie]

Does anyone else let spiders hang around the grow tent? I think they should be great for catching things like fungus gnats. I can’t swat those little bastards much anymore.. black floaters in my eyes makes it impossible. Grrrrrrr

I leave the spiders alone,they must be eating something .If you're getting fungus gnats you are probably over watering leaving an ideal humid environment for the eggs to hatch,perhaps use some sticky traps and run wet dry cycles.They feed on the roots as larvae,the adults are just a nuisance

Keep a mosquito dunk in your water/nutrient at all times and no fungus gnats, I know it works in coco, and assume it works in soil. Also yellow sticky traps on low branch above pot.

I leave spiders alone, but fungus gnats are going to breed a gazillion times faster.

Nematodes worked wonders for me, had a HUGE gnat problem and now they are all gone.

Ive got yellow stickies up. I was mostly wondering what anyone thought of spiders in the tent. I really don’t know how they find their way in or what they eat. I had my tent empty for a while when it was new and several spiders just showed up. This after I thought I thoroughly cleaned the grow room. Fungus gnats came in with bag of soil. The gnats are actually in my greens soil. I didn’t start the greens right so have small plants needing water often on the surface but moisture below. In a deepish planter box. I don’t see them flying around the MJ plants though really. Dead ones are floating in a water dish I have setup. Incidentally, this looks like another avenue for catching them, at least some help.

I rarely kill spiders unless huge and in living area. They can only help. Might try putting something yellow in water to attract more.

Sometimes in summer i can catch little jumping spiders and release them in my growroom. I can see them for months after that. They will catch some gnats but too less to count as ipm.

Mosquito Bits in your water. Don't forget the house plants too if you have any.

Once the pests get taken care of. Spiders die out naturally.
Mosquito dunks and yellow stickies are how I deal with
fungus gnats these days.

All predators and detritivores are welcome. With large pre-established populations of those newcomers can't really get a foothold. With large amounts of living soil I always have a couple gats, but that's about it. I do kill anything that flies, because you never know what is catching a ride. I like to fill in the blanks before nature does it for me.
