Rodent control is effectively accomplished by comprehensive rodent proofing, proper trapping, and environmental management. Look for signs of rodent activity. The District can assist homeowners in understanding:
Live rat sightings are a sure sign that an infestation is in progress, but may not occur until an infestation has become severe. To determine whether rodents are present inside or outside a home, look for these signs:
Rats can enter an opening the size of a half dollar (about ½ inch). Mice can enter openings much smaller. To keep rodents out, you will need to find and seal ALL access points. Carefully check the perimeter of your home for any openings, including:
Gaps around doors and windows, including garage doors. Poorly-fitting windows and doors should be replaced or repaired. Windows that are opened should have screens. Look for any gap you can put your thumb in – that’s a large enough gap for a rat to squeeze through.
Substandard repairs and remodeling can alter a structure’s rodent proofing. Repairs for rodent proofing are usually very simple and cost very little. Periodic inspection of your property should be conducted to insure that proper rodent proofing is still intact.
Rats dislike being out in the open, and will seek cover whenever possible. You can make your property less hospitable to rats by cutting back or removing vegetation and removing other items that provide cover for rats, especially close to your home and other structures.
