Hello, this thread is for pictures of cannabis related insects. Beneficial or pest. Try to find out the name of the bug, what they do, and how to remedy the problem if they are pests.

Fungus gnats.
Larvae eat organic matter in the soil including your plants roots. The adult flies carry a fungus on them called pythium that causes damping off to seedlings.

Sticky traps for adults
Nematodes or predatory soil mites for larvae.

Soil Mite
Eats decaying organics in soil

There are pest soil mites so be careful with who you let stay

Use predatory soil mites to keep a healthy balance in the soil.

Great idea for a thread.

The gnat larvae are only a few millimeters long, hard to see. This one was about an inch into the soil, munching on the root stalk.

Symphylans.
Soil dwelling insect up to 5mm long. They will eat organic matter in the soil including the roots of your plant. Fatal to seedlings and young transplants and they will stunt established plants.
Soil predatory mites will help. I also heard they are susceptible to drowning, but I don't believe it. I don't like soil pesticides unless its just a house plant, so my go to is predator mites and repotting. Good luck

Spring tails.
Don't fly. They use their tail to jump around.
They can be bad for seedlings. They eat organic matter with minimal damage to roots if there is enough food in the soil for them. Just a nuiscance.

These predator mites are slightly terrifying.
Stratiolaelaps Scimitus.
Predator mites that will combat fungus gnat infestations. They'll feed on multiple different types of larvae and insects in your soil, including those springtails. Beneficial to create a balanced ecosystem. They are expensive but you don't need a lot. I split the cost with 3 friends and only costed 16.50. Bought 10 000 for $50, good for 100 m² coverage. I could have split with more people.

Potential Soil Mite? No flyers on sticky traps, nothing on leaves or plant... growing in canna coco. Have had these before in a different coco grow that didn’t do well... irradicate or no worry?

pretty fast moving...

It looks like it has antenna. Mites do not have antenna. It would help to see how many legs it has, or a closer picture. I'm not sure what it is yet

Over the last week I have seen these small (1/4") caterpillars on my outdoor potted plants. They are eating at the leaves. I think they are Gypsy Moth. How do I get rid of them?

BTK kills caterpillars, look for Monterey or Thuricide. BTK is safe and only kills caterpillars.

If the pest has an exoskeleton de earth ur plants, let topsoil dry completely bc it is dust and has to remain dry, sprinkle dust around plant, you can wad up tp and dust your fans, dont dust flower, leave for 72 hours give a light flush check ph and you will be straight, even killed off thrips useing de and a bit of dawn, cheap and organic food grade de earth can be bought at any hardware store cheap.

I'm on the hunt for BTK - sold out everywhere (Toronto). Thanks.

Thanks for the info. I had never heard of 'de earth'. I can't seem to find BTK anywhere, so I will give this a try.

Hey its probably a little late, but those do look like fungus gnat eggs. Hard to tell for sure. I'll attach a picture from Google.

Found a strange bug, it was flying around in a dome immediatly after cutting clones. After using happyfrog for some sprouted seeds, I saw what i thought was a thrip. I finally caught one of them after a couple months of veg. So theu arnet infesting but i am unsure of their nature.
