When it comes to maintaining a healthy and beautiful lawn, understanding the top 5 lawn insects is crucial. These tiny creatures can cause significant damage to your grass blades, fruit trees, and ornamental plants if left unchecked. In this blog post, we will investigate the five most common lawn insects and discover ways to keep their populations in check.

Some of these critters are more than just an annoyance - they can quickly ravage expansive areas of your turf. By identifying the signs of infestation early on and implementing effective control measures, you can protect your outdoor space from chinch bugs, sod webworms, armyworms, fire ants, and mosquitos.

1. Chinch Bugs

Chinch bugs are small, pesky insects that can cause significant damage to your lawn during the summer months. These tiny pests feed on grass blades and release toxins that cause the grass to turn yellow and eventually die. In this section, we will discuss how to identify chinch bugs, their impact on your lawn, and effective ways to eliminate them.

Identifying Chinch Bugs

To spot a chinch bug infestation in your yard, look for irregular patches of dead or dying grass with a yellowish-brown color. The adult bugs are about 1/8-inch long with black bodies and white wings folded across their backs. They often hide in shady areas near sidewalks or driveways where they lay eggs on the soil surface or at the base of grass plants.

The Impact of Chinch Bugs on Your Lawn

Lawn Damage: As mentioned earlier, chinch bugs feed on grass blades by sucking out plant juices while injecting toxic saliva into them which causes discoloration and death of turfgrass.

Drought Stress: Lawns infested with chinch bugs are more susceptible to drought stress due to reduced root growth caused by these pests' feeding habits.

Weed Invasion: Damaged lawns provide an opportunity for weeds like crabgrass and dandelions to invade as there is less competition from healthy turfgrass plants.

Treating a Chinch Bug Infestation

If you suspect a chinch bug problem in your yard, it's essential to take action immediately before they cause further damage. Here are some steps you can follow:

1. Water your lawn: Chinch bugs thrive in dry conditions, so keeping your lawn well-watered can help reduce their population. Be sure to follow watering guidelines for your region.

2. Mow at the proper height: Mowing your grass too short creates an ideal environment for chinch bugs. Maintain a mowing height of 3-4 inches during summer months to discourage infestations.

3. Pesticide application: If you have a severe infestation, consider using a pesticide specifically designed for chinch bug control. Always read and follow label instructions carefully when applying any chemical treatments.

4. Hire professional help: For extensive damage or if you're unsure about treating the problem yourself, consider hiring a professional lawn care service like OneNeighbor. They will assess the situation and recommend appropriate treatment options based on their expertise.

Taking these steps can help protect your beautiful lawn from being destroyed by pesky chinch bugs this summer season.

Chinch bugs are one of the most destructive lawn pests, and can cause significant damage to your grass if left unchecked. Sod webworms are another common pest that feed on the leaves of turfgrass, creating large patches of dead or dying grass in their wake.

2. Sod Webworms

Sod webworms, also known as lawn moths, are a common summer pest that can wreak havoc on your beautiful lawn. These caterpillars feed on grass blades and can cause significant damage if left unchecked. In this section, we'll discuss how to identify sod webworm infestations and the best methods for controlling them.

Identifying Sod Webworm Infestations

To spot a sod webworm infestation in your yard, look out for these signs:

  • Brown patches of dead or dying grass
  • Tiny green caterpillars with brown heads crawling around your lawn
  • Moths flying low over the grass during dusk hours
  • Silken webs found near the base of affected grass blades

If you notice any of these symptoms in your yard, it's time to take action against sod webworms.

Controlling Sod Webworm Infestations

The most effective way to control sod webworm populations is through a combination of cultural practices and targeted treatments:

1. Maintain proper lawn care: Regular mowing at an appropriate height (usually between 2-4 inches) helps keep lawns healthy and less susceptible to pests like sod webworms. Additionally, avoid overwatering or excessive fertilization which may encourage their growth.

2. Natural predators: Encourage natural predators such as birds by providing birdhouses or birdbaths nearby. Birds love feasting on insects like caterpillars.

3. Biological control: Introduce Bacillus thuringiensis (Bt), a natural bacterium that targets caterpillars, including sod webworms. Apply Bt to affected areas according to the product label instructions.

4. Insecticides: If all else fails, consider using a targeted insecticide designed for controlling sod webworms. Make sure to follow the manufacturer's guidelines and apply during early evening hours when these pests are most active.

By staying vigilant and employing these methods, you can protect your lawn from the damage caused by sod webworm infestations this summer.

Sod webworms can be a major problem for lawns, so it's essential to spot and address them quickly. Moving on, armyworms are another common insect pest that can wreak havoc in your yard.

3. Armyworms

Armyworms are a common lawn pest that can cause significant damage to your grass during the summer months. These voracious caterpillars can create an eyesore by leaving behind discolored, brownish patches on various types of turfgrass. To successfully tackle an armyworm problem, it is necessary to first be able to recognize them in your lawn.

Identifying Armyworms

To effectively combat an armyworm infestation, it's essential first to recognize these pests' presence in your lawn. Adult armyworm moths are typically gray or brown with a wingspan of about 1-1/2 inches. Their larvae (caterpillars) vary from greenish-brown to black and have distinctive stripes running along their bodies.

You may notice signs of an infestation if you see birds frequently feeding on your lawn or observe irregular-shaped patches of dead grass appearing seemingly overnight. To confirm the presence of armyworms, try conducting a soapy water test: mix two tablespoons dish soap with one gallon water and pour over suspected areas; any present larvae should surface within minutes.

Getting Rid Of Armyworms

1. Maintain A Healthy Lawn: The best defense against any pest is maintaining a healthy lawn through proper mowing, watering, and fertilization practices - as well as regular overseeding and aerating when necessary.

2. Biological Control: Introducing natural predators such as beneficial nematodes or Bacillus thuringiensis (Bt), which is safe for humans but lethal for caterpillars like armyworms, can help control infestations. You can purchase these beneficial nematodes and Bt products online or at your local garden center.

3. Chemical Control: If the infestation is severe, consider using a chemical insecticide labeled for armyworm control. Always follow label instructions carefully to ensure safe and effective application.

4. Clean Up Debris: Remove any leaf litter, grass clippings, or other debris from your lawn regularly to eliminate potential hiding spots for armyworm larvae.

Taking swift action against an armyworm invasion is crucial in preserving the health of your lawn during the summer months. By learning how to identify these pests and implementing effective control measures such as biological treatments or chemical insecticides when necessary, you can keep your yard looking its best all season long.

Homeowners should be proactive in preventing harm to their lawns from armyworms, as they can cause extensive damage. Fire ants are another type of insect that can be a problem in lawns and gardens; they often build large mounds which disrupt the appearance of the landscape.

4. Fire Ants

Fire ants are a common lawn insect that can cause significant harm to your yard and pose a threat to you, your family, and pets. These aggressive insects build large mounds in the soil, which can lead to uneven surfaces and damage grass roots. Additionally, fire ant stings are painful and can cause allergic reactions in some individuals.

Identifying Fire Ants

To identify fire ants, look for their distinctive reddish-brown coloration and their nests - large dirt mounds with no visible entrance hole on top. When disturbed, these ants will swarm aggressively towards the source of disturbance.

Getting Rid of Fire Ants

The most effective way to control fire ant populations is through an integrated pest management approach that includes both chemical treatments and natural methods:

Baits: Use slow-acting granular baits specifically designed for fire ants such as Advion Fire Ant Bait. Apply according to label instructions around the perimeter of each mound or broadcast across infested areas.

Contact Insecticides: For immediate relief from active mounds or heavy infestations, apply contact insecticides like pyrethroids directly onto individual mounds following label directions carefully.

Natural Predators: Encourage beneficial insects like ladybugs and parasitic flies by planting native plants or using organic pesticides when possible. These predators help keep fire ant populations under control naturally.

Cultural Practices: Maintain healthy turfgrass by watering regularly (but not overwatering), fertilizing, and mowing at the proper height. Healthy grass can better withstand fire ant damage.

Although total elimination of fire ants is unlikely, by following the cultural practices outlined in Paragraph A, you can drastically reduce their numbers and minimize damage to your lawn. For more information on controlling fire ants in your yard, check out this Iowa State University Extension article.

Preventative steps should be taken to avoid the disruption fire ants can cause in lawns. Mosquitos are another common insect that can wreak havoc on your outdoor space; they're also known for transmitting dangerous diseases.

5. Mosquitoes

Mosquitoes, which can transmit diseases such as West Nile virus and Zika virus, are not only a nuisance but also pose serious health risks. In addition, mosquito bites can cause skin irritation and allergic reactions in some individuals. To protect your family and enjoy your outdoor space without the constant buzzing of these pesky insects, it's essential to take proactive measures for mosquito control.

Eliminate Standing Water

The first step in controlling mosquitoes is eliminating standing water around your property since this is where they lay their eggs. Check for any containers that may collect rainwater such as flower pots, bird baths, or old tires and empty them regularly. Additionally, clean out gutters and downspouts to prevent water from pooling up.

Use Natural Repellents

There are several natural repellents you can use around your yard to keep mosquitoes at bay. Planting citronella grass or lemon balm near seating areas will help deter these pests while adding a pleasant scent to your garden. You can also make homemade sprays using essential oils like lavender or eucalyptus mixed with water.

Maintain Your Lawn

A well-maintained lawn is less inviting for mosquitoes since they prefer tall grasses and weeds as hiding spots during the daytime hours when they're not actively feeding on humans or animals' blood source. Keep your grass cut short by mowing regularly and trim bushes back away from house foundation walls so there isn't dense vegetation in close proximity to windows, doors, entrances, homes, or structures which could provide shelter, harborages, or resting sites for adult females looking to lay eggs nearby water sources.

Install Mosquito Traps and Bug Zappers

Mosquito traps and bug zappers can be effective tools for reducing the mosquito population in your yard. These devices use a blend of warmth, illumination, or carbon dioxide to draw in mosquitoes and afterward either snare them or zap them on contact. Place these mosquito control devices around the perimeter of your outdoor living space for optimal results.

Hire Professional Pest Control Services

If you're still struggling with a mosquito infestation despite taking all necessary precautions, it may be time to call in professional help. A pest control expert from OneNeighbor will assess your property's unique needs and develop an integrated pest management plan that includes both chemical treatments as well as non-chemical strategies such as habitat modification and exclusion techniques to ensure long-term protection against mosquitoes and other common lawn insects and pests. By working together with the homeowner and neighborhood group purchasing service provider, homeowners can save money while ensuring their yards remain free of unwanted guests throughout the summer season and beyond.
