Possible reason for infestationThis client hadn’t had a pest control service for over 8 years, as her home was an older designed home with vinyl flooring in kitchens, this provided a vital breeding ground for small German cockroaches. These roaches breed rapidly! usually double the speed of the Australian or American roach. The house was also clean and tidy, these German roach infestations can also occur in immaculate homes only a few years old. The technician also noticed cans of DIY pest control sprays. The client unaware that these cans are usually useless on German roaches, As the shell is so thick on the small roach it’s difficult for the sprays to affect them. Treatment must be done using gels, flushing agents and a thorough initial assessment.

Description of work performed – A standard pest control service was done to the home also we completed a thorough service for German cockroaches,

Areas of property treated – This included internal external perimeter spray, dusting of wall cavitys/weep holes and roof voids. This usually is enough to treat a normal home. Due to the infestation of German roaches we also used gel in cracks and crevices throughout the kitchen, laundry and bathrooms. The corners of the vinyl flooring were also lifted and gel was applied to areas beneath. We then installed some glue/sticky traps to monitor the infestation, this was monitored on a second visit 14 days after the initial service. On the second site visit the customer reported only seeing 1.2 small roaches per day on the kitchen floor, usually moving very slow she said. We were confident our initial service was successful, however there was little gel left in the treated areas of kitchen, so gel was reapplied to areas to knock down any further early stages of cockroaches. We provided a call to client 14 days later to confirm a pest free home.
