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
