Protecting Your Pets from Pest-Related Health Risks in Davis

Protecting Your Pets from Pest-Related Health Risks in Davis

As pet owners in Davis, we want nothing more than the health and happiness of our furry friends. However, living in an urban environment means our pets face exposure to a variety of pests that can potentially transmit diseases or parasites. From fleas and ticks to rodents and mosquitoes, keeping pests away from pets takes diligence. In this article, we will discuss some of the top pest-related health risks facing pets in Davis and provide tips for protecting them.

Fleas and Ticks

Fleas and ticks are likely the most ubiquitous pests impacting pets locally. These small parasites can latch onto pets while walking in grassy areas or wooded trails and proceed to suck their blood. Beyond causing irritation and pain from bites, fleas and ticks also pose health risks by potentially transmitting diseases. 

For example, fleas are known to carry tapeworms. If a flea lays her eggs on a pet, the tapeworm larvae can infect the pet once it ingests the flea. Ticks also carry diseases like Lyme disease, ehrlichiosis, and Rocky Mountain spotted fever which they can pass to pets through their bites. Controlling fleas and ticks is crucial for keeping pets safe and comfortable.

Veterinarians recommend applying topical flea and tick prevention products year-round in Davis to create a barrier on the pet's skin and coat that repels and kills these parasites before they can latch on. Products containing ingredients like fipronil, permethrin, or selamectin work well. Grooming pets frequently also helps dislodge any fleas or ticks before they can infect the pet or lay eggs. Keeping yards free of excess leaves, brush, and tall grass where ticks may lurk assists too.


Mosquitoes buzzing around in the warmer months pose another risk, as some species can transmit heartworms to pets when they bite. Heartworms are parasites that live in the heart and lungs of infected pets and can be fatal if left untreated. Mosquito-borne illnesses like West Nile virus affecting both animals and humans have also been detected in some California counties including Yolo.

The best way to guard against mosquito-borne diseases is by giving pets heartworm and mosquito prevention year-round, even in winter. Medications containing ivermectin are commonly prescribed to kill developing heartworms and prevent transmission. Outdoor pet areas with standing water where mosquitoes breed should also be eliminated. Citronella collars or topical repellents applied to the skin may help deter mosquitoes from landing on pets.


Rodents like rats and mice can compromise pet health in several ways if they share living spaces with household pets. Rodents often carry diseases transmissible to pets through their droppings, urine, or bites. Some zoonotic illnesses rodents may carry include salmonella, plague, and hantavirus. 

Rodent infestations should always be addressed promptly through safe and humane exclusion and control methods. Sealing entry points and removing food and shelter sources eliminates attractants. Sterilizing areas exposed to rodents with disinfectants protects pets from accidental exposure to diseases. It's also wise to have rodents trapped and removed by a professional rather than allowing pets to catch them, as bites pose infection risks.


While raccoons are generally nocturnal, pet owners still need to beware of potential risks they may pose. Raccoons commonly carry rabies and can transmit it through bites or scratches. Stray or feral cats are another common rabies reservoir in some urban areas. Keeping pets vaccinated against rabies is a must for their protection. 

Additionally, raccoons have been known to prey on smaller pets left unattended, especially cats and small dogs. An unattended pet door makes it easy for a hungry raccoon to enter seeking food. Feeding pets indoors only and providing outdoor shelter securely fenced away from natural entry points helps deter unwanted raccoon encounters. Supervision when pets are outside also ensures quick intervention if needed.

Snakes and Spiders 

While less of a daily concern for most pets in Davis, snakes and spiders still warrant mentioning. Rattlesnakes are occasionally spotted sunning in drier open areas. Their venomous bites can severely sicken or even kill pets depending on the size of the snake, location of the bite, and pet's body size. 

To minimize exposure risks, keep cats and dogs on leash when in potentially snake-infested areas like tall brush. Do not allow pets to stick their noses into places where a startled snake may lash out in defense. Seek immediate veterinary care for any snake or spider bite.

Poisonous spiders like black widows also inhabit undisturbed areas locally. While their bites are rarely fatal to adult pets, they can still cause pain and require veterinary treatment. Keeping yards well-maintained removes potential hiding spots for medically significant spiders.

Prevention Tips in Summary

The best defense is a yearly wellness visit with the vet for vaccines, seasonal prevention medications, and parasite screening. Routine flea and tick treatments protect against common pests. Keep outdoor areas sanitized and free of shelter for rodents, snakes, and spiders. Make sure identification is always worn on collars in case pets get lost. Above all, monitor pets closely when outdoors and seek prompt care if anything seems amiss with their health or behavior after potential exposures to pests or wildlife. With diligence, pet owners in Davis can absolutely safeguard their furry friends from pest-related illness threats.
