Black flies
Mosquito_Haarlem_Hollandstarted grow question 4 years ago
dark-winged fungus gnats detected.
I immediately treated her with cinnamon water and covered the earth with sand so that they no longer nest.
Is this enough to kill them or does she need more treatment?

Put diatomaceous earth on top of your soil as well. It'll kill the larvae and any flies that get through the cover to go down and lay eggs.
- It's fairly cheap, and won't harm your plants, as it's a silica based rock grinded to powder.
Mrs_Larimaranswered grow question 4 years ago
well Fungus gnats are hard to fight,,, you must fight them in every stage,,,,,,,, Eggs and larvae in soil , :::: with predators
the flies with sticky traps( yellowstickers etc.
and all the remedies you already did
They are coming in " waves" just one fly lays eggs in the soil and week later you have hundreds
I treat every pot with Predators ( every growingpot in the house,,,,,,,with any kind of plant in it,,,,,,,) and i always lay some yellostickers onto the surface of the soil,,, so the little ones, that crawling out of the soil get trapped
but the worst ones are the larvaes, those foggers eat your roots

BugsJust noticed a small grey Rollie pollie looking big on one of my seedlings. Only found one and believe I killed it but what should I do to prevent/get rid of these bugs. I have another seedling that I didn’t see bugs on and a flowering plant that hasn’t had any issues with bugs

handelt es sich bei den Tieren um schwarze blattläuse? (Habe leider keine besseren Bilder hinbekommen)
Ich habe auch einige größere schwarze Tiere mit Flügeln an ähnlichen Stellen gefunden.
Denkt ihr mit Wasser und anschließend mit einer Seifenspirituslösung abspritzen reicht?

Pest infestation left my plant folded and weak. I treated it, but now blacked out leaves?Ants were farming an oval shaped bug's secretions that was eating my stem and going underground, leaving a trail of a film-like substance.
Treated it with neem oil, cigarette butt tea, garlic and dishwasher soap to fend them off. Black leaves now. Tips?

translucent pest in soilHi, last watering I've seen tiny translucent insects (about 1 mm) emerging from the soil. They are fast and can jump like a flea. I assume they live in soil. What are these little monsters, should I worry about them and what should I do ? TIA

First Grow 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?Last 3 days I've pruned diseased leaves every morning, foliar sprayed peroxide leaves & topsoil, & added some to watering solution. Is only affecting one plant in tent. Humidity no longer issue (was waiting 4 inline fan). If I keep pulling off leaves it's going to die anyway.

F44: dozens of gnats stucked on buds & sugar leavesHey,
I noticed dozens of gnats stucked on sugar leaves and buds trichomes/resin... I tried to pick them by hand but there are too many.
I saw articles about bud washing which seems to be a good thing except for higher mold risk.
Would it be the only way to smoke bug free weed?

What and why?What are these and do I need to address it?
I'm a couple of weeks in to my grow and just spotted these little critters when I was cleaning my run off saucers. I'm guessing there's more inside the soil are they harmful to my plants?
