Last year I had ant nests and earwigs living in my window boxes (1st
year for boxes) and coming in the house through the cracks around the
windows. (Very small cracks, and drainage holes in the windows.)

Would Horticultural Diatomaceous Earth work to stop these bugs, do I
sprinkle it on top or right through.

I sprayed the boxes with soapy water and this did not help.

Any other ideas?
