I recently moved into my house in Melbourne and noticed that there doesn't appear to be a chemical barrier in place for termite control. I found a sticker inside the switchboard that mentions a "Chemical Perimeter Spray & HG Collar" were applied in April 2021.
My question is: do I need to install a chemical barrier, or is the HG collar sufficient on its own?
I contacted the company that installed the HG collar, and they mentioned that an annual inspection/site visit is required. However, when I spoke to another pest control professional, he told me that once the collars are installed, no further treatment is necessary.
