Summer Pest Tips for the Lehigh Valley

Summer in Pennsylvania is beautiful, but it also brings a major increase in pest activity around homes. Warm weather, higher humidity, thick vegetation, outdoor food, and longer days all create ideal conditions for insects and rodents to become more active.

At County Pest Control, we believe the best pest control starts with understanding why pests are showing up in the first place. A good summer pest prevention plan focuses on three things: reducing food sources, sealing entry points, and modifying the areas around your home that make pests feel welcome.

Here are practical summer pest tips every homeowner should know.

Why Are Pests Worse in the Summer?

Pests are more active in summer because warm temperatures speed up insect development, increase breeding activity, and create more available food sources. Ants, wasps, mosquitoes, flies, ticks, spiders, cockroaches, and rodents all become more noticeable during the warmer months.

In the Lehigh Valley, summer pest pressure is especially common around homes with dense landscaping, mulch beds, standing water, exterior lighting, open trash areas, gaps around doors, and moisture problems.

The goal is not just to spray what you see. The goal is to make your home and property less attractive to pests in the first place.

1. Keep Vegetation Trimmed Away from the House

Bushes, shrubs, tree branches, vines, and tall grasses can all act like highways for pests.

Ants, spiders, ticks, mosquitoes, stinging insects, and occasional invaders often use vegetation for shelter, moisture, and access to the home.

A good rule is to keep bushes and branches trimmed back from siding, windows, doors, soffits, and rooflines whenever possible.

This helps reduce pest activity and also allows the exterior of the home to dry out faster after rain, which can make the area less inviting for moisture-loving insects.

2. Watch Mulch and Moisture Around the Foundation

Mulch looks great, but heavy mulch against the foundation can hold moisture and create ideal conditions for ants, earwigs, millipedes, centipedes, termites, and other insects.

Try to avoid piling mulch directly against siding, door frames, basement windows, or foundation gaps. Keep mulch thin near the home, and consider using a stone border in the first 6 to 12 inches closest to the foundation to reduce moisture and pest pressure.

Moisture is one of the biggest drivers of pest activity. If you have clogged gutters, poor grading, leaking hose bibs, or water pooling near the home, those issues should be corrected as part of a good pest prevention plan.

3. Eliminate Standing Water to Help Reduce Mosquitoes

Mosquitoes can breed in surprisingly small amounts of standing water. Birdbaths, buckets, flowerpots, clogged gutters, toys, tarps, wheelbarrows, and low spots in the yard can all become mosquito breeding areas.

Homeowners should walk the property weekly during mosquito season and dump any standing water.

For properties with heavy mosquito pressure, shaded areas, thick vegetation, or nearby woods, professional mosquito control can help reduce activity. County Pest offers mosquito options including targeted treatments and In2Care mosquito stations, which are designed to target mosquitoes where they rest and breed.

4. Seal Entry Points Before Pests Move Inside

Many summer pest problems start outside and eventually move indoors through small gaps.

Common entry points include:

• Gaps under doors

• Damaged door sweeps

• Openings around utility lines

• Cracks around windows

• Gaps around siding and trim

• Basement window wells

• Garage door gaps

• Openings around crawlspaces and foundation lines

Exclusion is one of the most important parts of long-term pest control. Sealing entry points helps reduce ants, spiders, mice, snakes, crickets, cockroaches, and occasional invaders.

For example, if a snake is found in a basement, the real solution is not just removing the snake. The best prevention comes from controlling the food source, sealing entry points, and modifying the habitat that attracted it.

5. Keep Trash, Recycling, and Outdoor Food Areas Clean

Summer heat makes trash and food waste more attractive to flies, wasps, yellow jackets, ants, raccoons, and rodents.

Use tight-fitting lids on trash cans, rinse recycling when possible, and avoid leaving pet food outside. If you grill often, clean grease buildup and food debris around the grill area.

Outdoor eating areas should be cleaned after use, especially if sugary drinks, fruit, meat, or pet food are present. These items can quickly attract ants, flies, and stinging insects.

6. Be Proactive with Wasps and Hornets

Wasps and hornets become more noticeable as the summer progresses. Early in the season, nests are smaller and easier to manage. By late summer, colonies are larger, more defensive, and more likely to cause problems around doors, decks, sheds, rooflines, shutters, playgrounds, and outdoor dining areas.

Do not seal an active nest opening in a wall void without proper treatment. This can force the insects into living areas.

If you see repeated wasp traffic entering a hole, soffit, siding gap, or shutter, it is best to have the area inspected and treated professionally.

7. Reduce Spider Activity by Reducing Their Food Source

Spiders are often a sign of other insect activity. Exterior lights, dense vegetation, webs

around windows, and insects gathering near doors can all support spider populations.

To help reduce spiders:

• Remove webs from windows, doors, soffits, and eaves

• Reduce insects attracted to exterior lighting

• Trim vegetation away from the home

• Seal gaps around windows and doors

• Keep basement and garage areas less cluttered

Professional spider control works best when it targets both the spiders and the insects they are feeding on.

8. Know the Difference Between Nuisance Ants and

Carpenter Ants

Not all ants are the same.

Pavement ants are often found along sidewalk cracks, patios, driveways, foundation edges, and concrete expansion joints. They commonly trail along edges and breaks in concrete.

Carpenter ants are more concerning because they can be associated with moisture-damaged wood. They do not eat wood like termites, but they can excavate galleries inside softened or damaged wood.

If you are seeing large black ants, especially inside the home, around windows, in the kitchen, or near moisture-damaged areas, a professional inspection is recommended.

The key with carpenter ants is finding the source, which is often outside in trees, stumps, rotting wood, or moisture-prone areas around the home.

9. Protect Against Ticks in Tall Grass and Wooded Edges

Ticks are commonly found in tall grass, leaf litter, wooded edges, fence lines, brushy areas, and shaded spots where wildlife travels.

To reduce tick pressure:

• Keep grass cut short

• Remove leaf litter and brush piles

• Create separation between lawn areas and wooded edges

• Keep playsets and seating areas away from overgrown borders

• Discourage rodents and wildlife from nesting close to the home

Tick control is most effective when the property is maintained and treatments are targeted to the areas where ticks are most likely to be active.

10. Do Not Ignore Moisture in Basements, Crawlspaces, and Attics

Moisture problems can create long-term pest issues. Damp basements and crawlspaces can support insects like silverfish, centipedes, millipedes, cockroaches, ants, and termites. Attic moisture can contribute to mold concerns, insulation issues, and wildlife problems.

Watch for signs like:

• Musty odors

• Condensation

• Water staining

• Soft wood

• Efflorescence on foundation walls

• Insect activity near damp areas

• Rodent droppings

• Damaged insulation

Pest control is most successful when moisture and building conditions are addressed along with treatment.

What Is the Best Way to Prevent Summer Pests?

The best way to prevent summer pests is to combine inspection, exclusion, sanitation, habitat modification, moisture correction, and targeted treatments.

At County Pest Control, this approach is called Integrated Pest Management, or IPM. Instead of relying on unnecessary spraying, we inspect the property, identify conducive conditions, and apply treatments where they are needed most.

This creates a smarter, more effective pest control program that is safer, cleaner, and better suited for families, pets, pollinators, and the local environment.

When Should Homeowners Call a Pest Control Company?

Homeowners should call a professional pest control company when they see repeated pest activity, insects entering the home, signs of rodents, wasp nests near living areas, termite activity, carpenter ants, cockroaches, bed bugs, or pests that keep returning after DIY treatments.

You should also schedule an inspection if you notice:

• Mud tubes

• Wood damage

• Rodent droppings

• Scratching sounds

• Heavy ant trails

• Wasps entering a wall or soffit

• Moisture issues with pest activity

• Unusual insect activity in basements, kitchens, bathrooms, or attics

Early inspections can prevent small issues from becoming larger and more expensive problems.

Frequently Asked Questions About Summer Pest Control

What pests are most common in Pennsylvania during the summer?

Common summer pests in Pennsylvania include ants, mosquitoes, ticks, wasps, hornets, spiders, flies, cockroaches, termites, carpenter bees, rodents, and occasional invaders like crickets, centipedes, millipedes, and silverfish.

Why do ants come inside during summer?

Ants often enter homes looking for food, water, or shelter. They may be attracted to crumbs, pet food, moisture, gaps around doors, foundation cracks, or trails leading from exterior nesting sites.

How can I reduce mosquitoes around my yard?

Remove standing water, clean gutters, trim vegetation, reduce shaded damp areas, and consider professional mosquito control for properties with heavy activity.

Are spiders a sign of another pest problem?

Spiders may indicate other insect activity because insects are their food source. Reducing exterior insects, webs, clutter, and entry points can help reduce spider activity.

What is the safest way to deal with wasps near my house?

Avoid disturbing the nest. If wasps are entering a wall, soffit, roofline, or high-traffic area, call a professional. Treating or sealing the wrong area can make the problem worse.

How do I keep pests out of my basement?

Seal gaps, reduce moisture, install proper door sweeps, repair foundation openings, keep storage organized, and address rodent or insect activity early.
