Think you can put used coffee grounds to keep bugs away. They are used around the foundation of a house to stop ants, iirc.
Iirc, you don't drink coffee anymore, you can get them at a local coffee bar (grocery store I shop at has a coffee bar) just ask them to save you a bag or two of used grounds. Tipping (after all you getting free sustainable insecticide) probably nets you warm fuzzy vibes from the barista (don't tell Mrs Blue, I mention that part)!
