Welcome to your weekly Pennsylvania bug bites forecast for October 12, 2026. This week, conditions across the state are decidedly mixed, with some regions still experiencing significant outdoor biting insect activity while others have thankfully gone dormant due to cooler temperatures. This unusual split, with lingering activity in some areas, is largely attributable to the much wetter than usual conditions Pennsylvania has experienced recently, with 136mm of rain compared to just 37mm during the same period last year, keeping standing water and breeding grounds more widespread than typically seen this late in the season. The accordion below still lists every city and town; dormant communities will receive seasonal local notes instead of a bite forecast, and we re-check temperatures every week to ensure accuracy.

In Northwest Pennsylvania, biting insects remain active this week. With daytime temperatures around 60.1°F and overnight lows near 58.7°F, conditions are still favorable for mosquitoes and other pests.

Northeast Pennsylvania also remains active, with temperatures hovering around 61.1°F during the day and dropping to about 58.9°F overnight, meaning you should still be prepared for encounters with biting insects.

Moving to Southwest Pennsylvania, the insect activity is likewise active. Daytime temperatures around 62.3°F and overnight lows near 60.3°F continue to support a notable presence of outdoor biters.

Finally, Southeast Pennsylvania is in a shoulder period, indicating a winding down of insect activity. With daytime temperatures around 58.8°F and overnight near 56.4°F, the cooler air is beginning to significantly reduce the numbers of biting pests, though some may still be present.

Moderate mosquito activity is possible at dusk, particularly near areas with poor drainage and lush vegetation. The past month’s higher-than-average rainfall has kept the soil moist and created more potential breeding sites. Tick risk remains low

🟡 ModerateElmwood

Mosquitoes will be moderately active at dusk, particularly around the John Heinz National Wildlife Refuge and other damp areas. The heavy rain experienced over the past month has sustained damp conditions, allowing these insects to remain active. Tick risk is low on park paths

🟢 LowPoint Breeze

A low risk of mosquito bites is present at dusk, primarily in immediate proximity to stagnant water in urban pockets. The area has seen a considerable increase in rain over the last month, which has kept the ground moist, but cool temperatures are mitigating overall insect presence. Tick risk is minimal

🟡 ModerateParkwood Manor

Moderate mosquito activity is expected at dusk, particularly near local ponds and wooded areas. The unusually high rainfall over the last 30 days has kept damp areas particularly saturated, prolonging mosquito season. Tick risk is low on park trails

🟡 ModeratePhoenixville

Dusk brings a moderate risk of mosquito bites, especially near the Schuylkill River and Black Rock Sanctuary. Much wetter conditions over the last month have contributed to more widespread dampness, supporting continued mosquito populations. Tick risk is low on wooded paths

🟡 ModerateLansdale

Expect moderate mosquito presence at dusk, especially near local creeks and damp, shaded areas. The region has seen significantly more rain in the last month, which has kept the ground saturated and prolonged mosquito activity. Tick risk is low on trails

Tick encounters remain possible on wooded trails, though overall insect activity is decreasing. The area has seen considerably more precipitation in the last 30 days than typical, creating ideal conditions for some late-season ticks

🟢 LowHorsham

Biting insects are mostly winding down, but a few persistent mosquitoes may emerge at dusk, particularly near marshy areas. Much wetter conditions than usual over the past month have led to more standing water in some spots

🟡 ModerateGrays Ferry

Be aware of mosquitoes at dawn and dusk, particularly near the Schuylkill River. The 30-day rainfall total, significantly higher than last year, means more residual moisture is available for insects

🟢 LowOgontz

Isolated mosquito activity is still possible during twilight hours, especially near any lingering puddles. This past month’s substantial rainfall, far exceeding the previous year, has sustained damp conditions longer than typical

🟢 LowWest Norriton

Trail walkers might encounter ticks, but mosquito activity is quite low. Local areas have absorbed a lot more rain in the last month than they did last year, keeping some habitats moist

🟢 LowHershey

A few late-season mosquitoes may be present at dusk, mostly near damp, sheltered areas. The region has experienced a significant increase in rainfall over the last 30 days, impacting local water levels and insect habitats

🟡 ModerateAllegheny West

Expect some lingering mosquito activity around dawn and dusk, especially near the Schuylkill. Much higher rainfall in the past month compared to last year has contributed to persistent dampness

🟡 ModerateLititz

Dusk brings a moderate chance of mosquito bites near Lititz Run, especially given the significantly higher rainfall this past month, creating more standing water. Ticks remain a low risk on wooded trails during the warmer parts of the day

🟢 LowCollingdale

Mosquito activity is low tonight, mostly limited to sheltered areas near standing water, though the recent month’s heavy precipitation has sustained some populations longer than usual. Trail users should still perform tick checks after walks

Check Pennsylvania bug bites against this week’s temperature, humidity, and rainfall before you pack. The city list above is the neighbourhood-level view; keep bite relief handy if you are heading outside.

About This Forecast

This weekly bug bite forecast for Pennsylvania is generated using current weather data from OpenWeather, geographic city data from GeoNames, and AI-written notes from Google Gemini. Quadrants are classified independently from this week’s temperatures, so part of a province or state can be dormant while another part stays in season. Store locations are sourced from Just Bite Me’s retailer database. Updates are refreshed weekly.
