Assuming that I apply DE outside in my yard/patio area. How often should I apply DE, following the 4lb bag per 800 sqft suggestion? How much time is recommended between applications?
Diatomaceous Earth 85% would not be applied out in the yard for insects, only around the home perimeter. Lightly coat a thin layer in areas where these insects are found such as patios, outdoor sills, window and door frames. Dust around foundations, along ant trails and around sewer pipes and drains. It remains effective in the control of insects as long as the product is present. It should be applied as needed if it is removed/washed away from the area.
