Richard from Toronto, Ontario, Canada writes
We placed 11 contrac blocks in the attic of our house to get rid of mice, and are concerned about possible effects of the vapors on us. We also placed several stations baited with Contac in the kitchen and basement. Is this safe for humans?
Contrac is a block rodenticide that does not release any vapors. If applied in tamper resistant bait stations it should pose no harm to humans if applied as directed.
