In these last warm evenings before the rains, the flying termites come out of their nests and start covering everything. I hate them. I actually stand outside with a racquetball racquet and a shoe and swing at them.
They also come in under the doors, shed their wings and start crawling around looking for somewhere to set up shot. Here's the tiles by the back door. Luckily a vast majority of our house is termite proof, but still.
