In the spring and summer, I get far too many flying insects infesting my garden, particularly in the early evening.
It appears to be a local mating area for many species and it is very annoying.
As an experiment, I've started trying to reduce the numbers by using a bug-zapper to see if this will have a knock-on effect in later years.
I can kill a hundred insects in one session with the zapper, but there is one species that forms a "cloud" that all seem to just randomly move around. The cloud is probably 300 individuals or more. Since the motion appears to have no purpose, this is what I assume to be mating behaviour. If I can kill them as they are about to reproduce, I think I might achieve my goal of smaller numbers next year.
The "cloud" seems to move with a certain amount of "wisdom of crowds" though, because as I move near with my zapper, they fly higher to be out of reach.
I want some method to be able to easily destroy the entire cloud at once - or the majority of them at least.
I have tried 1) Spraying them with a hose 2) Using a "weed-wand" to send flame into the air 3) Putting bug-zapper on a long pole
Number 3) Worked a little - but they just moved even higher after a while.
I have access to many tools and pieces of equipment. I'm also happy to spend a certain amount of money if necessary to reduce the problem.
