We had ants nesting in the walls of our house. We had called a couple other companies who just sprayed some powder in the roof & said that would get to the ants, dream on! One guy came back & tried something else, which slowed the ants for a couple of weeks, but they came back.
When Four Seasons Pest Solutions Inc came, he checked out the whole house, did their magic & we haven`t seen any ants (or anything else) since.
Great job , will recommend you to all my clients.
