Key Takeaway: California is home to a diverse range of rodent species, including the common pests of house mice, Norway rats, and roof rats. To prevent and control infestations, it is crucial to understand their behavior and habitat while implementing effective strategies such as sealing entry points, storing food properly, eliminating clutter, maintaining landscaping, and using traps or baits. Keeping homes and businesses clean is also essential in preventing rodent infestations and protecting human health from the diseases they carry.

1. Seal Entry Points

Rodents can enter buildings through small cracks and openings. It is essential to seal all entry points, including gaps around doors and windows, holes in walls, and gaps in the foundation. Use caulk, steel wool, or other materials to seal entry points and prevent rodents from entering.

2. Store Food Properly

Rodents are attracted to food sources, so it is crucial to store food properly. Keep food in sealed containers, and clean up spills and crumbs promptly. Do not leave pet food out overnight, as this can attract rodents.

3. Eliminate Clutter

Rodents love clutter, as it provides them with hiding places and nesting sites. Remove clutter from your home or business and keep it clean and organized. This will make it less attractive to rodents.

4. Maintain Landscaping

Rodents are attracted to overgrown vegetation, so it is essential to maintain landscaping. Trim trees and bushes away from buildings, and remove any debris or brush piles that could provide nesting sites for rodents.

Controlling Rodent Infestations

Despite your best efforts, rodents may still find their way into your home or business. In this case, it is crucial to take immediate action to control the infestation. The following are some effective strategies for controlling rodent infestations:

1. Traps

Traps are an effective way to control rodent populations. Snap traps, glue traps, and live traps are all effective in capturing rodents. It is essential to place traps in areas where rodents are active, such as near food sources or in dark corners.

2. Baits

Baits are another effective way to control rodent populations. Rodenticides are toxic to rodents and can be placed in bait stations or scattered in areas where rodents are active. It is essential to use baits carefully, as they can be toxic to pets and wildlife.

3. Professional Pest Control

If you are unable to control a rodent infestation on your own, it may be necessary to call in a professional pest control company. These companies have the experience and expertise to identify the source of the infestation and develop an effective control strategy.
