When you’re out, use DEET and cover yourself. Try to only apply it to your clothes. It’s toxic to humans.

If you have control of the land around you, make sure there’s no stagnant water nearby. If you want to keep a pond, manage your mosquito population using local species if possible. In some places, you can also report stagnant bodies of water.

If they’re inside, check your window screens. If you can’t afford that, use a mosquito net, and check my first answers.
