It is generally not recommended to seal off the space between a gas range and kitchen counters, or the space between the stove and the wall, with spray foam. Spray foam is flammable and can pose a safety hazard when used around gas appliances. Additionally, it may interfere with the proper ventilation of the gas range, which is crucial for safe operation.
Instead of using spray foam, here are some alternative options to prevent mice from getting in:
Seal gaps and cracks: Inspect the area around the gas range and the wall for any gaps or openings that mice could use as entry points. Use steel wool or copper mesh to fill in these openings. Mice cannot chew through these materials, unlike foam or rubber.
Install rodent-proofing materials: Consider using rodent-proofing materials, such as metal kick plates or flashing, to cover any larger gaps or openings that may be difficult to seal with steel wool or copper mesh. These materials are more durable and resistant to rodent gnawing.
Keep the area clean: Mice are attracted to food sources, so maintaining a clean kitchen and minimizing food debris can discourage them from entering. Wipe down countertops, sweep the floor regularly, and store food in airtight containers.
Use deterrents: There are various natural deterrents that may help keep mice away. Peppermint oil, for example, is said to repel mice due to its strong scent. Soaking cotton balls in peppermint oil and placing them near the openings can act as a deterrent. Similarly, some people have found success with using ultrasonic pest repellent devices, which emit high-frequency sound waves that are unpleasant to mice.
Consult a professional: If you're experiencing persistent issues with mice infestation, it might be beneficial to consult a professional pest control service. They can assess the situation, identify entry points, and provide targeted solutions to prevent mice from entering your kitchen.
Remember, it's essential to prioritize safety when dealing with gas appliances. If you have concerns about the gas range or need assistance with sealing gaps near the appliance, it's recommended to consult a licensed professional or contact the manufacturer for guidance.
