Most animals are repelled by hemp which makes it an ideal insulation material to limit the entry of rats and mice into your home or building.
Hemp insulation is a natural repellant for rodents, mites, and termites due to silica being present in the fibre, which is a naturally occurring mineral found in the hemp plant. Another benefit of hemp insulation is that it has very little protein for pests, and the hemp materials mechanical strength makes the fibres not ideal for rodents to use for their nesting.
This insulation is safe to the touch and contains no harsh chemicals. Whats more, in the low event that you have a pest intrusion, you can rest assured that your insulation will suffer little to no damage.
