Here in central Georgia, we’ve got lots of mosquitoes (and other bugs)--I do a few things to keep them away. 

Talstar-Pro (Talstar P – bifenthrin) – I spray this around the outside of my house, around the perimeter of my property (I have a lot of woods behind my property), bushes & trees.  From Spring to the beginning of Fall, I spray once a month for mosquitoes.  I’ll also spot spray ants if I see them—but it’s also good for a bunch of other insects.   You mix it ~1oz/gallon of water in a sprayer.

I’ve been very happy using it the way that I do; however, I suggest caution when using it.  Read about Bifenthrin before using it to understand how and why to apply it.  I wouldn’t use this indoors, or around ponds (bad for fish), or if you’re growing flowers where you’re concerned about bees or butterflies—not good for them.  Also, some areas restrict its usage.

Advion Ant Gel – I’ve used this for ants, both indoor & outside.  I haven’t had ants indoors for at least 10 years, though, since I’ve used the Talstar Pro outside.  When I’ve used it, I’ve put it down where the ants are running back & forth—in about a day, they’re gone (it’s bait they take back to their “home” and kills them there).

Peppermint – I have a large container on my patio that I grow peppermint in—it’s a deterrent for mosquitoes.

Peppermint Oil – because of all the hummingbirds I have from July thru September (and gallons of sugar water), I have had to deal with yellow jackets getting at the feeders (I avoid spraying Talstar-Pro around the feeders).  Up until a few weeks ago, I just killed them by hand—there were only a few at a time, and so it’s been manageable. 

I had read that wasps & bees do not like peppermint, so I put some springs of peppermint from my plants around the feeders—but it had no effect on the yellow jacket activity. 

So, I thought would try some peppermint oil since it is more concentrated. 

It works.  I haven’t killed a yellow jacket in 2 weeks—I’ve seen a couple, but they don’t hang around—they don’t like it.  I put a dropper full of the oil on a cotton ball I’ve got strapped to the feeder “station” – I re-apply it every 2-3 days. 

@stringy  If you don't mind smelling like candy canes, maybe peppermint is the answer for you 😉
