Placed out rodent bait stations-3 outside, 3 basement, 2 deck access room, 3 kitchen, 2 room under stairs. I applied a liquid residual treatment for spiders and general pests to exterior foundation and interior baseboards. Best results seen in 10-14 days. Weâ€™ll return in 30 days to start your quarterly service with another exterior application and inspection of rodent devices. Any concerns let us know. Thank you for choosing Green Pest Solutions.
