Chemical soil barrier
Termiticide is worked into the ground at the footings and slab penetrations until the soil the house sits in reads as one treated zone. Modern non-repellent products give no warning of themselves, so foragers walk through and ferry the dose home to the colony instead of steering around it.
- Best when
- There is active pressure and you want protection working the day it is finished.
- The trade-off
- It needs full, even soil access, which is harder near waterways, wells or under-slab services, and it is renewed over its service life.
