Fungus gnat help!
I had fungus gnats a few months, but ended up repotting all my plants in new soil and moving to bottom watering only. Now, with spring I’ve has my windows open more often and have noticed fungus gnats flying around again! I’m managing adult populations with sticky cards, but I can’t find any larvae in the soil and I’m not sure how they are reproducing since I’ve been exclusively bottom watering to keep the top layer of soil dry. Any suggestions?
I got an electric fly trap and that seemed to solve my problem. This is the model I bought (cheaper on eBay): Katchy Indoor Insect Trap - Catcher & Killer for Mosquito, Gnat, Moth, Fruit Flies - Non-Zapper Traps for Buzz-Free Home - Catch Flying Insect Indoors with Suction, Bug Light & Sticky Glue (Black) https://smile.amazon.com/dp/B07B6RZP4H/ref=cm_sw_r_cp_apan_i_0260CGKE78NDHN32FMSG?_encoding=UTF8&psc=1
@tmbryant37 Good idea! The sticky traps seem to be handling adults, but I’m sort of wondering how they are even living if the top inch of soil is dry?
Unless they are hiding somewhere deep inside they shouldn't be, but they also could have taken up residence on something non-plant I suppose. The electric one did the trick for me and cleared them up in a few days. It does most of the work at night when the room is dark and the flies are attracted to it's light. They fly in and hit the sticky trap at the bottom which you can change as needed very easily
They seem to be rooting around in my pothos even though the soil is dry, not sure what they are doing. But I’ll look into this electric trap, thank you so much!
