Yeah my gameplan was to spray it around the perimeter and see if it helps. Open to any other suggestions to stop mosquitoes from over taking my place lol

I had success using it for years on 1.5 acres. You need to spray grass, brush, eves, leaves on trees that you can reach, so your whole yard. Mosquitos live on the underside of all this stuff, so the more you spray the better the results. I have a tank sprayer that can be both a boom and a wand sprayer.

It helps with spiders and red ants. First spraying needs to be followed up by a second one in 2-3 weeks then every 2-3 months. Keep pets off of grass for a few hours after spraying.

Avoid flowers as it will kill bees and anything you will consume like fruit trees.

I tried to spray when no rain for a day or two, but generally rain isn't a problem for it.

pretty much any insecticide will kill mosquitos, you just have to be persistent. no matter how long the residual lasts, killing on contact is always most effective (and satisfying).

Add in 1 oz per gallon of mineral oil for outside spraying. You will get a longer residual. The oil doesnt evaporate as quickly as does with water alone.

Spraying works......for a while. And then you will spray more, and then more, and more. Insecticide/chemical companies love that model.

Spraying to protect your immediate living area is one thing, and is generally fine. Broadcast spraying, or completely drenching everything can be counterproductive and expensive. New research is actually showing that mosquitoes can develop an immunity, or tolerance, to many insecticides. However, other insects that feed on mosquitoes in all life stages (larvae to adult) do not develop such resistance to chemicals, or at least not as quickly and readily as mosquitoes.

Spray if you have to, but what would work better in the long run is working to increase the number of birds and mosquito predating insects in your area.

I know a guy who has a vernal pool in his backyard. He designed it and he keeps it up. You would think his place would just be covered up with mosquitoes, but that isn't the case. What he does have a large number of are dragonflies, damsel flies, water bugs, and as of this year.....at least one species of frog (tadpoles). All of those feed voraciously on mosquito larvae. As a result, mosquitoes aren't much of a problem at all for him. The only thing he sprays is immediately around his home to keep ants and spiders at bay, and some diatomaceous earth for some box elder bugs this time of year.

Maybe worth the shot to change the way you look at things to get out of the cycle of perpetually dumping chemicals into the small part of the ecosystems we do control.
