Contrac All-Weather Blox Rodenticide would not be used in the oven at all. Itcan be used indoors but it is not recommended as they can die anywhere inside the home & you will not get rid of the smell till the body is found & removed. If they are inside your oven, you will need to take it apart to remove the body/bodies. Indoors we only recommend using snap traps & glue boards as it will hold the body till you can remove it
Contrac All-Weather Blox Rodenticide is not labeled to be used directly in burrows. It should only be used in tamper resistant bait stations placed in runways, near burrow entrys etc within 100 feet of structures.
