I searched for "plaster of paris pest control" and found the MYTHOLOGY OF
CONTROL, from the University of Nebraska, 1990:

"Plaster/Cement and Rats
"Boelter (1909) states that plaster of paris (calcium
sulfate) mixed with sugar has long been recommended as a
rat poison. This bait is placed near water. When the thirsty
rat drinks, the plaster hardens in his intestinal tract and
"literally stiffens him." Fitzwater (1990) fed caged rats (Rattus
norvegicus) plaster of paris mixed 50% with their dry feed.
He also fed a mixture of portland cement in the same ratio
to a second set of rats. After 14 days on these diets, there
was no mortality in either test and the animals appeared
perfectly healthy except for sore rectums due to their large
bowel movements. It is probably safe to assume the digestive
fluids in the alimentary tract prevent these substances from
hardening. Other suggestions along this line, such as
dehydrated potatoes and bath sponge or cork pieces soaked
in butter or bacon fat, can be presumed to be equally

I seem to remember seeing a recipe for squirrel bon bons. I
think it was 50/50 peanut butter and plaster aparis. They
eat the bon bons and they don't return. Squirrel problem

Good luck,
