Hello, today I was here for your follow up. I applied a liquid residual throughout the seems of the mattresses, bed frames and box springs targeting bed bugs. I applied an aerosol solution as a knockdown throughout the carpeted areas targeting bed bugs. I could not treat sofas due to too much personal belongings on sofas. I was unable to properly treat certain areas due to mass amounts of personal belongings. If you need us to come back for another treatment I highly recommend decluttering areas to properly treat. Please allow 10-14 days for the product to take effect. If you have any issues please contact our office. Thank you for choosing green pest solutions.
