Ant moats are a simple low-tech way to protect any building from termites,
carpenter ants etc. About 6' from the house dig a moat one foot deep in the
gound- put the small construction debris (except cement based and plastic) in the
moat- sawdust, small pieces of wood, EPS, anything that will trap air. When
you are done cover the moat with 4" regular topsoil and insert some small
pipes into the moat about every 12' apart- dose the moat with sugar water- about
one cup each pipe. You will get colonies of ants living in the moat - AND
NOWHERE ELSE. These ants are territorial and will keep everything away from the
house- and they are cannibals. Refresh the sugar water twice a year.
The topic came up in a discussion of straw bales homes.
The "best" ant will come to find a nice living place in your house and stop at the moat- you just have to remember to feed your colonies occassionally. We have used ant moats in over 100 of our super-insulated homes to keep ants "on-guard" against other invaders. The idea was developed in the early 80's by us and the folks at Cornell University. It's too "low-tech" to be popular and doesn't benefit anyone commercially- except the home owner- so it has never spread much. It does work- so welcome to use the technique.
