With a lot of tree cover and a nearby river, the one fly in the ointment(!) at our new place is it has a lot of mosquitos and midges. The latter don't seem to be too much of a bother but the mosquitos, living in long grass and ivy especially, must be of some particularly virulent sub-species or I'm just very sensitive to them: when bitten nothing happens for a day or so, then I get a large swollen lump anything up to a 2" (5cm) across. I may also get raised blisters or it may start continuously weeping for 2-3 days. That's just off one bite!
From a gardening perspective, can I do anything to keep the place clear of them? I know they breed in standing water but with a river nearby I can't eliminate that. I've started clearing ivy which they seem to love, to reduce damp places for them to hang out, but I'm wondering about a more drastic solution - similar to how I go out with my back-pack of weedkiller, can I treat areas with some sort of pesticide - is this even legal, let alone feasible?
In terms of the bites themselves (well, that's a bit off-topic)... but should I find my reaction moderates with repeated exposure? Or could the opposite happen like with people getting more and more allergic to peanuts until it's dangerous?
