I have never seen a roach in my home which is a mobile home above ground. Six months ago I had a "water beetle" and placed sticky traps under appliances and furniture in all rooms. After a week all traps were empty. This week I found these two on different days but the same area close to my deck slider door. Also this week my mobile home park began infrastructure projects on gasolines, water main and a block long retaining wall replacement. Could the two sigtings be due to displacement from construction or should I begin pest control treatment and if so what should I use?
