Electrical Work Can Disturb Hidden Pests

Cockroaches love electrical boxes, switch plates, and the warm spaces behind outlets. When an electrician opens up walls or conduit, they often find cockroach nests that have been thriving in the dark, warm cavities. This is your opportunity to treat the problem before everything gets sealed back up.

Schedule Khun Clean's natural cockroach treatment alongside your electrical work. We apply food-grade diatomaceous earth inside wall cavities and around electrical conduit entry points — places you can't reach once the job is done.
