Proactive treatment of carpenter ants
Two of my neighbours have problems with carpenter ants in their homes. (including my next door neighbour and the house next to hers). Our houses are pretty close together and have not yet seen any evidence. Does anyone have any suggestions on how to prevent them from coming our way? Non-toxic to kids and pets is important for us too.
A neighbour mentioned a silica-based product applied to the foundation? Some neighbours have nests in their 60-year old front lawn sugar maples. Not sure where other nests are.
Thanks so much!
