Mosquitoes are more than just a seasonal annoyance—they can pose serious health risks to your pets. Dogs and cats are both vulnerable to mosquito bites, which can lead to skin irritation, allergic reactions, and even life-threatening conditions like heartworm disease.
At 1st Pet Veterinary Centers, we want to help you protect your pet with trusted, compassionate care. Whether you need prevention advice, treatment for bites, or ongoing heartworm protection, our veterinary team is here for you.
Do Mosquitoes Bite Dogs and Cats?
Yes—mosquitoes bite both dogs and cats, especially around sensitive areas like the ears, nose, and belly. Even indoor pets aren’t completely safe from bites, as mosquitoes can easily get inside homes.
In mosquito-heavy regions and during warm months, the risks increase. That’s why veterinary-guided prevention is so important—1st Pet is here to help you make sure your pet stays protected.
What Can Mosquito Bites Cause in Cats and Dogs?
Mosquito bites can lead to more than temporary itching. Some of the most serious consequences include:
-
Heartworm disease: Transmitted through mosquito bites, heartworms are deadly if left untreated. Dogs are most at risk, but cats can be affected too.
-
Skin irritation and allergic reactions: Pets may develop welts, swelling, or itching, sometimes intense enough to cause self-injury.
-
Secondary infections: Excessive scratching or licking can break the skin, leading to infections that may require veterinary care.
Important Note: Pets cannot get heartworms from drinking water with mosquito larvae—transmission only happens through bites.
If your pet is showing signs of discomfort or symptoms of heartworm disease like coughing, fatigue, or weight loss, contact us at 1st Pet right away.
Spotting and Treating Mosquito Bites on Pets
Recognizing mosquito bites early can help you avoid complications. Look for:
-
Red or swollen bumps on the skin
-
Constant licking, chewing, or scratching
-
Discomfort around the ears, face, or belly
Safe at-home treatment includes:
-
Gently cleaning the area with pet-safe soap and water
-
Applying vet-approved anti-itch sprays or creams (never human medications)
-
Preventing excessive scratching to avoid infection
If the area worsens or your pet seems unusually uncomfortable, our veterinary team at 1st Pet can assess the bite and recommend treatment.
Natural Mosquito Repellents That Are Safe for Pets
Natural repellents can be helpful—but not all products are safe for animals. Always check with your veterinarian before using anything on your pet.
Vet-approved natural ingredients include:
-
Lemon eucalyptus oil (in pet-safe formulations)
-
Cedarwood and lavender blends
-
Geraniol-based repellents designed for animals
Avoid DEET, which is toxic to pets. Apply repellents before outdoor activity, especially at dawn or dusk, and reapply after swimming or heavy play.

Pet-Friendly Plants That Help Repel Mosquitoes
Gardening for mosquito control? Some plants offer a natural deterrent and are safe for your pet:
-
Lemon balm
-
Rosemary
-
Basil
-
Catnip
-
Marigolds
These can be planted along garden borders or kept in patio pots. However, avoid citronella grass and geraniums, which are toxic to pets. Always check the ASPCA’s list of pet-safe plants—or reach out to us for guidance.
A Layered, Veterinary-Guided Approach to Mosquito Safety
The best way to keep your pet safe is to combine multiple strategies—and your vet is your most important partner in that plan.
At 1st Pet, we recommend:
-
Year-round heartworm preventatives for both dogs and cats
-
Regular heartworm testing as part of routine care
-
Vet-approved repellents and treatment plans
-
Environmental mosquito control (removing standing water, using screens, etc.)
Even indoor pets need protection, and our team is here to make that easy and effective.
