Why This Happens

Mosquitoes don’t just bite people—they bite animals too. When mosquitoes feed, they can pass along parasites and diseases from one host to another.

Pets that spend time outdoors are exposed more often, especially during dawn and dusk when mosquitoes are most active. Warm, humid weather increases mosquito populations, which increases exposure risk.

In Northern Virginia and Southern Maryland, long mosquito seasons mean pets may be exposed for months at a time.

What This Means for Your Home

For pets, mosquito bites aren’t just itchy—they can be more serious over time. Some mosquito-borne illnesses affect the heart, lungs, or immune system, especially in dogs.

Cats and dogs may also scratch or bite at irritated areas, leading to skin infections. Because pets can’t avoid mosquitoes on their own, they rely on their environment being managed properly.

If mosquitoes are heavy in your yard, your pets are being exposed every time they go outside.

How Professionals Address It

Professional mosquito control focuses on reducing mosquitoes where pets live and play.

The process starts with inspecting the property for breeding areas like standing water and shaded resting zones such as shrubs, mulch beds, and foundation plantings. These areas are where mosquitoes spend most of their time.

Control is exterior-first and targeted. By lowering mosquito populations around the home, professionals help reduce how often pets are bitten—without unnecessary interior treatments.

What Homeowners Can Do Now

• Remove standing water from bowls, buckets, and toys

• Keep grass trimmed and shrubs thinned

• Check gutters and planters after rain

• Limit pet outdoor time at dusk when possible

• Keep pet resting areas away from dense vegetation

Avoid using foggers or DIY sprays around pets. These often provide limited benefit and can create safety concerns if misused.

When to Call a Professional

If mosquitoes are persistent and your pets spend regular time outdoors, a professional inspection can help identify why populations are high.

Reducing mosquitoes early in the season helps protect pets long-term and makes your yard safer and more comfortable for the whole family.
