About 3 months ago, I suddenly saw a couple rats in the backyard. I searched around and signed a full year contract with Green City Pest Control. They explained for me to understand that the rats are common in Seattle area and educated me that the vines touching the house might lead the rats inside the house or the attic. They set up traps for the rats and place the baits inside the traps, inspect the traps and change the bait once a month. The number of rats reduce a lot in 2 months. They also spray chemicals to kill spider outside and around the house. They also place baits in the holes to get rid of the mole and so far I did not see any mole or its activity. I hope after a year, there will not be any rats/ moles and spider in the back yard. I recommend Green City Pest Control if you need their service.
