We are currently renting a home in Fox Island, WA, we have lived here for almost 6 years and have no problems. within the past three months, we have a massive problem with rats in the crawl space. We called in the professionals who explained to the exterminator what was going on as I started to get these wierd scabs and bites in my arms and calves. They are driving me crazy,,The only thing I know is there were some carpet beetles found but the yellow larvae is burrowing under my skin. at first they itch and then they burn. our landlord put some poison under the house to kill the rats but did nothing to the inside. it seems that the bugs are coming into the house...........only after dark.
