Fungus gnats 😫🤢

Help! I’ve watered with 4:1 ratio water to hydrogen peroxide and that’s helped but the adults can live for two to three weeks!

What can I use to kill them? They are driving us up the walls!

Mosquito bits in your water and yellow sticky traps

Systemic granules on top of the soil and watered in good worked for me. It kills the larvae when they feed on the roots so you have to wait for a few weeks for the adults and new hatchlings to die but I recommend it.

Same. SG has made summers so much easier without all the pests

It’s what’s in mosquito bits. It’s basically death by flu. It’s a bacteria called Bacillus thuringiensis israelensis. Kills the bugs, safe for pets and kids.
