I wonder if putting the thing on a time switch such that it's on for
"a while" and off for "a while" would improve the lack of
effectiveness of one that is always on. With one that is on they
could just get used to it where as one that goes on and off would be
far more irritating, especially if it wasn't a regular cycle.

I'm not sure what time period "a while" would be. As I said earlier
they do give a start when it comes on so that happening every couple
of minutes would be pretty irritating. Think of some one giving a
blast on a pneumatic drill every few minutes would be like, maybe
with some longer on periods so they can work out where it's coming
from and move away (or chew through the wires...). B-)

Peanut butter and raisins are good baits as I recall.

Peanut butter goes rancid, Nutella doesn't (it doesn't even go
mouldy!...) Raisins are good for sticking on the prongs of a back
breaker type trap.
