Nematodes

Hi just been wondering if any1 used Nematodes and added them to the soil? Here’s a pic

Yes

yes, worked well.

Worked well on my house plants in combination with these yellow glue things (whats their name in english?). Those are also handy to monitor the effectiveness/reemergence of the flies.

I have used them a couple of times to combat fungus gnats. They always seem to do the job.
