Mosquitoes I’d normally focus on doing a full yard treatment of a granular, we’d use bifenthrin back in my day, no idea what they’re using now (but bifenthrin is still on sale), you can use a spreader from Home Depot and it just takes a light dusting.

But as a sibling comment said, making sure your gutters don’t have standing water, or that there are little ponds without fish, is going to be your best bet. A big problem is going to be stuff near you, as their range can be 1-3 miles.

So, live in a well developed area with lots of people around taking care to avoid mosquitoes? You’re right it’s a hard one.

I know many tropical countries have successful stories fighting mosquitos by simply removing every single place that might contain water: ponds, flower pots etc.

it's not going to eradicate them, but if you just want your patio clear for an evening thermocell (and the knock-off refills from aliexpress) work great.

removing standing water on your property is a good start, but mosquitoes are a lot more mobile than roaches, so you'll need to do a lot bigger area than a normal residential lot for it to be very effective.

Deet. You just need to keep em off you.

Also fine fly screens reduce it to an outside problem.
