Understanding Different Mosquito Species in Western Pennsylvania and How to Keep Them Away
Published June 15, 2026
Western Pennsylvania's humid summers, wooded landscapes, and abundant rainfall create the perfect environment for mosquitoes to thrive. While many homeowners think all mosquitoes are the same, several different species are common throughout the Pittsburgh region, and each behaves differently.
Understanding which mosquitoes are living around your property can help you better protect your family, pets, and outdoor spaces.
Meet the Mosquitoes of Western Pennsylvania
1. Asian Tiger Mosquito (Aedes albopictus)
The Asian Tiger Mosquito has become one of the most common and aggressive mosquito species in Southwestern Pennsylvania.
How to identify them:
- Black body with bright white stripes
- White stripe running down the center of the back
- Smaller than many native mosquito species
Behavior:
- Bites aggressively during the daytime
- Common around patios, decks, and outdoor living areas
- Highly attracted to humans
Breeding sites:
- Flower pots
- Bird baths
- Children's toys
- Buckets
- Clogged gutters
Unlike most mosquitoes that emerge at dusk, Asian Tiger Mosquitoes can make enjoying your backyard difficult throughout the day.
2. Northern House Mosquito (Culex pipiens)
The Northern House Mosquito is one of Pennsylvania's most widespread mosquito species.
How to identify them:
- Light brown coloration
- Less distinctive markings than Asian Tiger Mosquitoes
- Medium-sized body
Behavior:
- Most active during dusk and nighttime
- Frequently enters garages, sheds, and homes
- Feeds primarily on birds but will bite humans
Breeding sites:
- Storm drains
- Rain barrels
- Standing water
- Neglected swimming pools
This species is particularly important because it is one of the primary carriers of West Nile Virus in Pennsylvania.
3. Woodland Mosquitoes
Many Western Pennsylvania homeowners live near wooded areas, creating ideal habitat for several woodland mosquito species.
Behavior:
- Thrive near forests and shaded landscapes
- Common around wooded property lines
- Can travel significant distances from breeding areas
Breeding sites:
- Woodland puddles
- Temporary pools of water
- Low-lying areas
- Tree cavities
Properties bordering woods often experience significantly higher mosquito pressure than open lots.
Why Mosquitoes Love Western Pennsylvania Yards
Many local properties naturally provide everything mosquitoes need to survive.
Mosquitoes prefer:
- Shade
- Moisture
- Dense vegetation
- Standing water
- Protected resting areas
During the hottest parts of the day, mosquitoes typically hide in cool, shaded locations such as:
- Shrubs
- Ornamental grasses
- Groundcover
- Under decks
- Wooded property edges
These are the same areas professional mosquito treatments focus on.
Eliminate Mosquito Breeding Sites
Mosquitoes need water to reproduce, and surprisingly little water is required.
Check your property weekly for:
- Bird baths
- Flower pot saucers
- Children's toys
- Wheelbarrows
- Buckets
- Clogged gutters
- Tarps
- Pet water bowls
Even a small amount of standing water can support mosquito development.
Improve Your Landscaping
Routine yard maintenance can significantly reduce mosquito populations.
Consider:
- Trimming overgrown shrubs
- Removing excess vegetation
- Cleaning up leaf litter
- Increasing airflow around landscaping
- Maintaining proper lawn height
A well-maintained landscape gives mosquitoes fewer places to hide and rest.
Professional Mosquito Control Delivers Better Results
While homeowners can reduce mosquito breeding sites, professional treatments target the areas where mosquitoes spend most of their lives.
A professional mosquito control program focuses on:
- Shrubs and landscape beds
- Property perimeters
- Dense vegetation
- Under decks and patios
- Wooded edges
- Shaded resting areas
Routine treatments throughout the season help keep mosquito populations under control and allow families to spend more time enjoying their outdoor spaces.
