5 Proven Strategies to Prevent Rodent Infestations

Rodents are characterized by their continuously growing, razor-sharp incisors. These teeth have thick enamel on the front and thinner enamel on the back. To prevent the teeth from overgrowing and piercing the skull, rodents must constantly wear them down. As they grind against each other, the softer dentine at the rear wears away, leaving a sharp, chisel-like enamel edge.

Most rodents possess up to 22 teeth, lacking canines or anterior premolars. A gap, called a diastema, exists between the incisors and cheek teeth in most species. This allows them to pull in their cheeks or lips to protect their mouth and throat from inedible debris, which is expelled from the sides of their mouth.

1. Seal Entry Points 
   Rodents can squeeze through openings as small as ¼ inch. Inspect your property thoroughly and seal all potential entry points, focusing on doors, windows, and pipe penetrations.

   Suggested Materials:

   – Stainless Steel Mesh: Durable and chew-resistant.

   – High-Density Foam: Provides strong sealing when combined with mesh.

   For best results, use a “sealant sandwich”: apply foam, add mesh, and cover with more foam. This method seals cracks effectively. Avoid using expandable foams alone, as rodents can chew through them.

2. Establish a Vegetation-Free Zone 
   Maintain a clear area around your building. Keep trees and shrubs at least six feet away to reduce hiding spots and access points.

   Landscape Maintenance Tips:

   – Trim overgrown plants.

   – Avoid ground covers that conceal burrows.

3. Inspect Incoming Goods 
   

   Rodents can stow away on shipments. Inspect all incoming goods thoroughly to catch any hitchhiking rodents and prevent infestations.

4. Implement Rodent Monitoring 
   A robust monitoring program is vital. Regularly inspect areas like ceilings and wall voids for rodents.

   Recommended Tools: 

   – Monitoring Traps: Place in areas with rodent activity.

   – Exterior Monitoring Devices: Use around dumpsters and dense vegetation.

5. Keep Waste Areas Clean 
   Rodents are attracted to messy waste areas. To deter them, keep dumpster lids closed, seal trash and recycling bins, and store materials like cardboard in sealed containers to reduce attraction.
