When it rains a lot, usually that's when the ants try to find a place that is dry. Call your pest guy. They will take care of it immediately and usually by spraying the perimeter of your home, and placing some ant traps that are much more effective than the traps available in stores.. It is part of the yearly "deal". In this tropical paradise, a contract with a pest control business is extremely important.
OH NO...If you have ants, Jane will have uncles. She is arriving here soon. Hope all is well at her house. She has had more than her share of "critters" and hasn't even really taken permanent residence.
