Well, the land is a fixed 4 acre spot in Texas.
I've heard of the thermacells. I'll be googlin' those.
Hmmm... Marigold mist. I'll check that out too.
Back when I PCS'ed to Texas in 2012, I bought a house up in Richardson. Had a great patio with a pergola. I had 3 of those citronella spirally things that you lit up and let smoke and a ceiling fan and an oscillating fan and a clip on repellant doohickie on my belt. Also a chiminea with the Pinon wood.
I was smoking a cigar and drinking a Duvel one evening and looked down and saw a mosquito sitting on the clip on thing... sunuvabich... ;-)
