Woodrat control can be achieved by following a comprehensive approach, which involves using multiple methods together for maximum effectiveness. Keep your home free of rodents by implementing this proactive, 3-step routine: trap, repel, and monitor.
The key to successful trapping is proper trap placement. Make sure to place traps in areas where you have noticed signs of high rodent activity. According to statistics, more rodents are caught on the first night than on any other night, so it is crucial to use a number of traps initially. Some rats are “neophobic,” or extra cautious of new objects that suddenly appear in their environment, which makes them harder to catch. You can stay ahead of these cautious pests by placing rat traps out and leaving them baited but unset for a few days before finally setting the traps.
The next step is deploying repellents. Ultrasonic rat repellers effectively drive away rats by emitting high frequency sound waves. The devices use non-repetitive patterns to prevent rodents from becoming accustomed to the sound. Ultrasonic frequencies do not travel between walls, so ultrasonic units need to be placed in multiple rooms. Scent rat repellents use scents that rats find unpleasant or overpowering, such as peppermint oil, to naturally drive rats away.
It's crucial to note that using repellents alone won't control an established infestation. Instead, they should be used alongside traps, sanitation, and rodent-proofing efforts. Once the infestation is under control, continue using repellents to prevent rats from returning.
Lastly, monitor your home to prevent their return. Deploy traps to monitor for signs of new infestations so you can act before the problem becomes more serious. Rodent populations will increase with easy access to food and shelter. Particular attention should be applied to roofs, eaves, attics, and soffits. Overhanging trees and vegetation limbs should be cut back from rooftops by 6 feet.
Exclude rats by sealing off all openings to your home. Rats only need ½" opening, or the size of a nickel, to gain entry. Eliminate clutter around your property. Woodrats nesting inside homes often continue to feed outside, so be sure to reduce easy food sources. These include garbage, outdoor dog pens, vegetable gardens, compost piles, or bird feeders.
