When using Alpine Foam around the perimeter of a home for carpenter ants, how often should you apply it?
Alpine Foam is meant for treating ants inside the wall voids and small crack and crevice areas inside and around the outside of the home. It is no meant to be applied around the perimeter of the home, like a spray. Instead of using the foam inside cracks and crevices, and places where pipes enter the home every month, it would be much better to apply a product like Dominion 2L, which is applied out of a 1 gallon hand pump sprayer. It is much easier to take care of ants by spraying a larger area that ants can crawl over easily near the house instead of treating each individual crack around the house. Also, the spray will last 60 to 90 days so it does not require as much treating as the foam.
