i have a customer who is a little skeptical about installing a paver patio because of ants getting under them and causing problems. i'm never really encountered this question before so i was a little stumped on what to tell her. besides her needing to address her "ant problem" within her property, what do i tell her, or do to esure i won't have ant problems under her patio? i think it all comes back to lawn and property insect treatments. any suggestions?
