Extended Product Information
FAQs
Is this product toxic to pets?
No, the wire wool is a physical barrier and the peppermint oil is a natural deterrent that is not harmful to domestic pets when used as directed.
Can I use this outdoors?
Yes, the wire wool is rust-resistant and designed to handle outdoor conditions, such as gaps in exterior walls or garden structures.
How many pads come in the kit?
The kit includes 8 large wire wool pads.
Do I need to replace the pads regularly?
If installed correctly, they act as a long-term barrier. However, you should inspect them every few months to ensure they remain firmly in place.
Will the peppermint scent wash away?
While the oil might fade over time due to weather, the primary deterrent remains the physical wire wool barrier itself.
Can this be used for birds or larger pests?
It is primarily designed for rats and mice. For larger pests, you may need a more robust physical mesh or structural repair.
Troubleshooting
Wool keeps falling out of the hole
The hole may be too wide or the material was not packed tightly enough. Use more wire wool to create a denser plug or use a sealant like barrier foam to hold it in place.
Rodents are bypassing the barrier
Ensure the barrier covers the entire void. If rodents are going around the wool, you likely have other unsealed gaps nearby that require additional pads.

Setup, Compatibility & Care
Identify Entry Points: Conduct a thorough inspection of your home to find where rodents are accessing the structure.
Preparation: Clean the area of any loose debris or dust.
Application: Take a section of the wire wool pad and press it into the gap. Use the included tamper to ensure the material is packed firmly so it cannot be pulled out.
Sealing: For larger gaps, combine the wire wool with expanding foam to ensure the barrier stays in place permanently.
Care: Inspect the areas quarterly to ensure the wool has not been displaced by external elements or animal activity.
