I second the thermacell if you are sitting in one location. Got tired of buying those little butane cartridges and and bought one of these that runs on camp stove fuel. On my second year with current large canister. A bigger investment but less fooling around in the long run.

These things are awesome if you are sitting around. I've used them for a few years now.
There are a few versions out there too I like this one. One tank will last days.
Thermacells work like a magical force field. I've used them hunting in the early fall and you can actually see the mosquitos not entering a small bubble around you.

This one linked is bigger and works better for hanging out, the small ones work well for one person.

This works really well.
