I live in an area with a large number of mosquitoes. After a lot of trial-and-error, here's what I've found works.

Don't use a bug zapper. The zapper does kill things, but... the zapper also attracts bugs from far away into your area. If you have a large property, a zapper placed far away at the boundary can pull bugs away from the living area.

You can pay a company to come spray your yard frequently, but it gets expensive over time. I bought a gas-powered fogger (https://www.amazon.com/dp/B0746S92WW) and the chemicals: Insecticide and Insect Growth Regulator (https://www.amazon.com/dp/B00RW197XG and https://www.amazon.com/dp/B005CT9IDO)

Spray everything once a week initially, then you can try dropping down to every other week. Very few mosquitoes remain.

Further, look into repellents: https://www.nytimes.com/wirecutter/reviews/best-bug-repellen...

Mosquitoes are weak flyers; if you want to defend a static area, like a picnic table, a large fan can be used to keep a breeze up over the area and keep mosquitoes out.
