Part of a thorough rodent control program includes repairing structural areas where rodents can get in, but sometimes it’s impossible to seal all potential entry points. That’s where EVAC Botanical Rodent Repellent, a “green” EPA-registered product made with plant fibers, fragrance oil and balsam fir oil, comes in: Simply place the 2.5-oz. pouches in non-living areas where rodents traditionally nest, and replace the product when scent has diminished. The pleasant pine scent is formulated to be repellent to rodents. EVAC is particularly effective at preventing rodent entry into such hard-to-seal places as crawlspaces, boats, RVs and storage buildings, the company says.
