We get a lot of inquiries from customers who are wondering when they should change out the Inspection Cartridge located inside their Advance Termite Bait Station. As explained in our termite control article, you should inspect them every 45-60 days. Upon inspection, you should find them to be in one of three conditions: 1) No activity and in pretty good shape. 2) Damage and rot but no insects. 3) Live termite or other insect activity.
The following video walks you through the process of inspection and should help educate you as to when you should change one or leave it be.
