Mosquitoes seem to be especially prevalent around the river, where they like to fly up and bite me while I'm fishing. I get a dialogue pop-up that I was bitten and that it's itchy, but I've had several at this point, and so far, they don't seem to be as bad as bee stings (which you need medicine to treat). I was worried that they would potentially interrupt me while I was trying to reel in a fish, but the pop-up at least seems to come after the catch, so there's no actual interruption.
Are there any negative effects to mosquito bites, other than the (mildly) annoying popup? Is there any way to avoid getting bitten, or is this just something I'll have to deal with all summer?
