Good morning. Today I was here for your initial service. I applied a liquid residual solution to interior back porch, interior of barn and exterior of home, barn and shed for carpenter ants and general pests. Treatment can take 2 or more weeks to control an existing ant population. We use non-repellent insect controls for ants, which will not prevent ants, therefore requires contact and will address the colony. Please try not to kill the ants, we need them to take our products back to their colony. If you have any questions, please contact the office anytime. Thank you for choosing Green Pest Solutions.
