Fungus Gnats Under Cover

Bipetual · July 17, 2015

I am growing in five gallon SIP made from buckets. I have noticed some fungus gnats and the last time I had a lot of them I used a soil drench of Gnatrol with good results. But this year I am using plastic covers, and I am a little reluctant to disturb them. Some of them are actual shower caps and work fine but they are a little brittle. I think they would tear if I lifted them up.

Also, we have had tons and ton of rain and since the containers are homemade the drainage probably isn't as good as it would be with commercial containers. I really hate to saturate them from the top.

Any other way of dealing with them? I do have yellow sticky traps out, but they seem to be of limited use.
