Good afternoon, it was nice speaking with you on the phone today! I completed your service for fleas. I treated throughout the entire interior of the building with a liquid residual for fleas. This includes all baseboards and carpeted areas of both apartments, the basement, and the salon. Please wait at least four hours for treatment to dry before re-entering any of these areas. Allow two to three weeks for full effect. I recommend daily vacuuming throughout the building during this period. This will encourage flea eggs to hatch and help to clean up live and dead fleas, which will speed up the treatment process. If you have any questions or concerns, please give us a call. Thank you for choosing Green Pest Solutions!
