Some friends of ours in town use some service. It is guaranteed. If you see a mosquito (or tick) they come back the next day and spray again.
Im not a huge fan of spraying because it harms other insects. But it is tempting.
Screen porch ftw as well.
Some of our neighbors treat for mosquitoes. Hubbardston is a giant swampy forest. So unless you drop a ton of DDT, the mosquitoes would laugh.
Foggers work a bit for a few hours. We didn’t plan on doing the fire tonight so I didn’t have any on hand.
