Hm. Interesting. I try to give advice too, but I really have no idea if people respond or not. I mean, ofcourse I do know it when people do respond, but I don't know it when they don't. I don't go looking up my posts to check that.

Me neither. But some people are easily offended by the behaviour of others.

Update on this.

I looked at the site Auk recommended, and ordered a package of sticky traps to hang in the tree. The one trap I hung up has a lot of bugs stuck to it, probably less than a hundred. It is bright yellow which may attract them. The trees all seem to be big free.

So, once again, good advice from the forum and, particularly, Auk.

I am a big fan of Yellow Stick Traps. For White fies and Fungus gnats mostly. Not very pretty on a bench, but they get the job done.
