I'm struggling to manage a worsening infestation of fungus gnats in my plants. I've tried everything from mosquito bits and neem oil to repotting and drying out the soil, but they just keep coming back, often worse than before. At one point, I discovered a pot filled with larvae after a neem drench, which was a real shocker. To make matters worse, I've started dealing with aphids and mealybugs on a few plants too. I spend a lot of time wiping them off with rubbing alcohol, but it doesn't seem to be effective. Winter is approaching, and I thought pests were less active in the cold, but they seem relentless. Does anyone have any effective tips or advice on how to tackle this issue? I love my plants, and it's really stressing me out!

Have you tried using mosquito bits properly? They’re supposed to kill larvae effectively if used right. I fill a plastic bottle with filtered water, add the bits, let it sit overnight, and then give the plants a good drench, focusing on the first inch of soil. You might also want to consider applying a systemic pesticide if the problem persists, but tread carefully with those. You could also put outdoor-tolerant plants outside for a month; ladybugs can help manage aphid populations!
I appreciate the advice! I realize now that I may not have soaked the bits properly. I'll definitely try your method. What systemic pesticide do you recommend?
I manage a bunch of indoor and balcony plants, and I run a Katchy trap at night for gnats. Whenever I notice a pest, I treat all my plants with systemic granules or miticide. This preventive method has kept pests at bay for me most of the time. Just remember to maintain that routine!
Thanks! I'll consider getting a Katchy trap. Do you think the sticky traps really help? I'm worried about making my plants feel uncomfortable.
Definitely helps! Just make sure they’re placed away from direct sunlight, so they won't affect your plants too much.
I totally feel your pain! Mosquito bits and neem oil have struggled to help me with these gnats too. What worked for me was using hydrogen peroxide instead! Mix 4 parts water with 1 part peroxide and water your plants with that. Just make sure to soak the top of the soil. It usually takes about three rounds to completely eliminate them. Fingers crossed this helps you, it's an inexpensive method to try. I've even lost a greenhouse to mealybugs before, so I understand your frustration!
Thanks for the tip! Is there a specific type of peroxide I should be using? I've only seen hair peroxide before, and I'm not sure if that's the right kind!
You want to use regular hydrogen peroxide, just be sure it's not too concentrated. Most stores will have it at a 3% solution, which is perfect!
Just be cautious with any systemic; Acetamiprid is effective, but you have to be careful with application around wildlife.
