Hello. Sorry we missed you today. I completed your pest control service. Dryer vent is full of lint and can be a fire hazard, I suggest taking off screen and pulling out the lint. treated the exterior of the home for ants, spiders and general pests by applying a liquid residual treatment to the foundation, around doors and windowsills. You may see an increase in activity for a few days, this activity will decrease over time. Please allow 2 weeks for our treatment to take full effect. Our office can help you with any questions or concerns. Thank you for choosing Green Pest Solutions.
