Design the birdhouse for the specific species you want. Instead of expensive and dangerous insecticides to combat tiny pests like aphids and spider mites, consider these good bugs. The tiny Spider Mite Predator bug will consume 10 adult mites or 20 eggs daily. Update Bulletin No. It gets pleasantly cool some summer evenings and I would like to draw in more air without using noisy fans.
Warm air is less dense.
In a two-story house, open your second floor window fully. Open your first floor window slightly less. The warm air moving out the upper windows draws cool air in the first floor. Since these windows are not opened as far, the air velocity is higher creating a cooling breeze.
