How to get rid of the buggers?
we have a moat (I suspect therein lies the problem) and a small pond which dries out in summer.
I am past the repellant stage and moving towards anihilation. BUT father in law has a pheasant run which encloses the moat, so any chemicals need to be bird friendly.
The moat has no fish, and as its a scheduled monument we would probably not be allowed to put fish in. Besides its a bit dodgy looking so might well kill them anyway. It was overgrown and we took all bankside trees away last year, so there is no new leaf fall into the moat, and its got sunlight (well, not at the moment.....)
so, what do I use? Fumigation/gas/pellets something in the water???? any deterant on the platforms of the campsite yurts/domes in the wood??
any advice would be fantastic
