Do you mean spearmint leaves, or is it a liquid spearmint? How do you use it--do you put outside the house along the foundation walls? If it's outdoors, it would probably go away if it rained, I would guess. Anyway, just curious about all this.
I spray spearmint extract (online) outside and in doorways. I've actually put Wrigley Spearmint Gum in kitchen cabinets to keep them out of there when invading. A good chunk of bugs do not like Spearmint and flee the area. For fun put a piece of Spearmint gum on an ant hill. Funny. I put both baby powder and Spearmint on window sills if I ever see any ants. I've put a circle of baby powder around large ant hills because raid tends to kill the grass for a year.
