i keep my snake in my room which is at the back of the house. summer in Oklahoma is ridiculously hot sometimes, so this state can be a mosquito heaven. i havent seen any mosquitos in my room, but i suppose they could get in when im not around.
if you're referring to her enclosure, i keep her in a 50 gallon tank with a grate top. i dont think any mosquitos could make it through the grate, but i could be wrong...
