Rodent Infestations in California: Most Common Causes and Prevention Tips

Rodent infestations can be a nuisance and pose health risks. Whether it’s mice, gophers, squirrels, or rats, understanding the most common causes and implementing preventive measures can help keep these pests at bay.

California is home to a diverse range of rodents, with over 35 species identified within the state. These rodents encompass a variety of sizes and habitats, from the tiny deer mouse (Peromyscus maniculatus) to the larger California ground squirrel (Spermophilus beecheyi).

Most Common Causes of Rodent Infestation and How to Deal With Them

Rodent infestations can be a major problem for homeowners, as they can cause damage to property, spread disease, and contaminate food. Once you have determined the cause of your rodent infestation, you can take steps to prevent it from happening again. Here are some of the most common causes of a rodent infestation and some tips to avoid any infestation from happening:

1. You have various food sources.

Rodents easily get attracted to food sources. From pet food and unattended water bowls to dripping faucets and leaky pipes, expect inviting rodents in search of an easy meal and hydration source. Improper storage or disposal of garbage and food waste can also attract and provide a food source for rodents, encouraging them to settle nearby.

What to do:

• Store food in airtight containers.
• Clean up spills promptly.

• Fix leaks and ensure there are no standing water sources.
• Store garbage properly.

2. You live near dense rodent populations.

If your home is near areas with dense rodent populations, such as overgrown vegetation, trash piles, or abandoned buildings, the chances of a rodent infestation increase. It might be difficult to handle what’s beyond your control, but you can definitely mitigate this problem.

What to do:

• Inspect your home for any holes or cracks.
• Seal up holes and cracks with caulk or steel wool.
• Regularly clean and dispose of garbage and vulnerable areas properly.

3. You have secluded areas at home.

Rodents seek out secure and secluded areas to build their nests and raise their young. Cluttered spaces, piles of debris, and undisturbed areas like attics or crawl spaces provide ideal nesting grounds for rodents.

What to do:

• Seal gaps or holes in walls, floors, and foundations that provide entry points.
• Use traps to catch rodents.

4. The weather conditions are unfavorable.

Changing weather conditions, particularly during colder months, can drive rodents indoors in search of warmth and shelter. Heavy rains, snowfalls, or drastic temperature drops can increase the likelihood of rodent infestations.

What to do:

• Make sure to always keep your home clean and clutter-free.
• Trim trees and bushes back away from your home to prevent rodents from using them to climb up to your roof or into your attic.

5. You have unattended maintenance and repairs.

Overlooking routine maintenance and repairs can create openings or favorable conditions for rodents to enter and establish a foothold in your home. Tall grass, dense vegetation, and piles of debris can also provide hiding spots and nests for rodents. Keep your yard well-maintained.

What to do:

• Clutter provides hiding places for rodents.
• Keep living and storage spaces organized and minimize hiding spots.

Ultimately, it’s important to regularly inspect your home for signs of rodent activity, such as droppings, gnaw marks, or rub marks, can help detect infestations early on. If you have concerns about rodent infestations, consider consulting with a pest control professional for guidance.
