Summer in Pennsylvania is an exciting time of year when we are greeted with warm weather, longer days, and more outdoor activity. Unfortunately, fair weather is also prime time for insects that come out of hibernation searching for food, shelter, and water.
As we venture outside to make the most of this time of year, many pests can make our backyards a nightmare. Fortunately, there are solutions available, including our Home Protection Plans, which defend against over a dozen common species of pests in Eastern Pennsylvania.
With that said, here are the ten most common summer insects in Pennsylvania and some summer pest control tips to keep them at bay.
1. Ticks
These nasty, blood-sucking parasites can pop up anywhere. Ticks are commonly found in areas with thick foliage, high grass, or even in grass clippings. You don’t have to go hiking in the deep woods to spot ticks either. They can be found as close as your backyard.
Not only can their bites leave painful swelling, but ticks also carry dangerous diseases like Lyme and Rocky Mountain Spotted Fever.
The best way to deal with ticks is to keep your yard clear; ticks are drawn to overgrowth. If you are heading outdoors, wear repellent with DEET to keep these parasites off. It’s also a good idea to wear long sleeves and pants if you plan on going into the deep woods.
Always check your body for ticks after hikes or outdoor activities. If you should find a tick on you, a loved one, or a pet, you should remove it immediately.
For a longer-term solution, consider a yard barrier spray that can keep ticks and mosquitoes away for the summer months.
2. Termites
While termites are active year-round, warm, humid summer weather is prime time for swarming activity. Swarms often occur after rain and can indicate a nearby colony.
Termites feed on cellulose-based materials, including wood, cardboard, and paper, and can cause serious structural damage if left untreated.
To prevent termites, remove wood debris from around your home, keep mulch at least a foot away from your foundation, and fix leaks that create moisture. Regular inspections can also catch termite activity early before major damage occurs, but the only sure solution is a termite bait station.
3. Mosquitoes
These nasty biting insects are the deadliest pests. Not only do they leave itchy welts after they bite, but they also spread dangerous diseases like West Nile, Zika, dengue, and yellow fever, among others. Mosquitoes can also spread heartworm to domesticated dogs.
To keep your home mosquito-free, take steps to stop your yard from becoming overgrown and remove any standing water. Mosquitoes breed in standing water so removing any leftover after a rainstorm is critical to your defense.
4. Spiders
Many different spiders are out and about during the summer in search of other insects. While most are harmless, some can be very dangerous, like the brown recluse.
Generally, they stay away from humans and are beneficial for killing pests. But they can be found in gardens and on lawns.
Plus, you’re more likely to run into some, including the deadliest variety, if you are outside. The best way to avoid these insects is by keeping your yard clear and using caution when gardening.
5. Ants
Ants are very active during the summer. These insects can be troublesome based on their sheer numbers.
Ants can form colonies in dirt mounds, dead or dying trees, and plenty of other areas, taking over your garden or yard. Additionally, they can find ways inside through little cracks and holes.
They can become “ants at a picnic,” and sometimes that picnic is in your pantry. A simple way to stop an ant invasion is to spray them with soapy water. This will eventually kill them, and they can simply be vacuumed up.
6. Cockroaches
Cockroaches love heat and humidity, which makes summer their favorite season. These pests are more than just creepy; they can spread bacteria and allergens that trigger asthma and other health issues. You might spot them near drains, under sinks, or in basements.
To keep them out, seal cracks around your home, fix leaky pipes, and keep food sealed and trash taken out. If you spot more than one roach, it could indicate a larger infestation that needs professional attention.
7. Bed Bugs
Travel is more popular during the summer, which means you may be more likely to encounter bed bugs. Be sure to check your hotel rooms, luggage, and clothes should you take a trip. Before returning home, if possible, run your clothes through the dryer on high heat to kill off any potential bed bug stowaways.
8. Ladybugs or Asian Lady Beetles
Ladybugs can actually be helpful insects when they stick to your garden. They feast on all manner of garden pests and are generally harmless.
The real pest is the Asian Lady Beetle. This invasive species looks very similar to the ladybug, but they can be much more of a nuisance should they find their way inside.
Often, they are called “overwinter pests,” and they hatch during the warmer months, swarming inside your home. An easy way to get rid of these nasty-smelling imposters is by sucking them up with a vacuum and relocating them far from your home.
9. Centipedes and Millipedes
These creepy crawlers are known biters. They both carry venom that can be toxic or harmful to anyone with venom sensitivities.
Typically found in damp, cool areas, these insects won’t usually make themselves known to humans. They also tend to be more active at night. The best way to deal with these pests is by keeping your home dry. Run a dehumidifier in rooms with excessive moisture. Also, get rid of any potential hiding spots.
10. Stinging Insects
Bees, wasps, hornets, and yellow jackets are all part of the stinging insect family. While these insects tend to leave humans alone, they build their nests out of sight and are territorial. Most stinging insects will get aggressive and attack.
The first step to treating this issue is locating the nest. The problem that comes with removing them is knowing whether you’ve found a bee’s nest or some other nasty insects.
Bees are essential pollinators and should be removed by a beekeeper. If you don’t have bees, you might have a more aggressive stinging insect. If you want to avoid being stung, this may be a job for a pest control expert.
Summer Pest Control Tips: Preventive Measures
Don’t let insects crash your summer fun. The key to staying pest-free is prevention. Here are a few tips to keep your home and yard protected all season long:
- Eliminate standing water: Mosquitoes and gnats love stagnant water. Empty planters, buckets, and birdbaths regularly.
- Trim back overgrowth: Tall grass, weeds, and dense shrubs create hiding spots for ticks, spiders, and other pests.
- Seal up entry points: Inspect windows, doors, and your home’s foundation for cracks and gaps. Seal them to block unwanted visitors.
- Store food properly: Ants, roaches, and flies are all drawn to open food and crumbs. Keep indoor and outdoor dining areas clean.
- Schedule regular pest inspections: A pest control professional can spot the signs of infestations early and offer safe, effective treatments.
This summer, protect your yard and home. Take the proper steps to keep your yard clean and cared for to avoid any possible infestations.
Be sure to protect your property by sealing any openings or cracks and ensuring that unwanted invaders don’t ruin your summer.
