Help to stop the Mrs sell my house

Poison is designed to take a few days to kill mice and rats. Rodents are extremely suspicious of anything new (neophobic) and if there are several of them, then one will be nominated as “food tester”, the others will only take the poison if it seems to be having no ill effect on the tester rodent. Snap traps baited with peanut butter placed along the mouse’s run (look for a greasy mark along a wall) are very effective.
