Understanding Why Wasps Are in Your Grass

Wasps can be more than just a nuisance when they start buzzing around your yard. Understanding what attracts them and their habits can help you manage and prevent infestations. 

Here’s why wasps might be drawn to your grass.

  • Attraction to food sources. Wasps love food, and your yard might offer plenty. Fallen fruit from fruit trees, nectar from sweet-smelling flowers, and leftover food and drinks from outdoor gatherings are major attractants.

  • Searching for grubs and larvae. White grubs. like Japanese beetle grubs, in the soil attract wasps. Blue-winged wasps and cicada killers, for example, lay eggs on these grubs, making your lawn their hunting ground.

  • Nesting habits. Wasps build nests in the ground, trees, and crevices around your yard. Common species like yellow jackets, paper wasps, and baldfaced hornets choose different spots to set up their colonies, which can be problematic if near high-traffic areas.

Types of Wasps Commonly Found in Grass

When it comes to wasps in your yard, it's helpful to know the different types you might encounter. Here’s a quick guide to solitary and social wasps and the characteristics and behaviors of various wasp species.

Solitary wasps vs. social wasps

Solitary wasps prefer to work alone and do not form colonies or wasp nests like their social counterparts. Examples of solitary wasps include blue-winged wasps and cicada killers. 

On the other hand, social wasps, such as yellow jackets, paper wasps, and baldfaced hornets, live in colonies and build nests that house multiple wasps.

Different wasp species

  • Blue-winged wasp. These solitary wasps are beneficial as they hunt and lay eggs on Japanese beetle grubs, helping to control these pests in your lawn.

  • Cicada killer. Large and intimidating, a cicada killer digs burrows in the ground for their eggs. Despite their size, they are generally not aggressive toward humans.

  • Paper wasps. Known for building umbrella-shaped nests under eaves and in trees, paper wasps are social wasps that can become aggressive when their nest is threatened.

  • Yellow jackets. Highly aggressive and often found building nests in the ground or structures around your yard, yellow jackets can be a significant nuisance, especially in late summer when their colonies are at their peak.

  • Baldfaced hornets. These social wasps build large, football-shaped nests in trees and shrubs and can be very aggressive in defending their nests.

Signs of Wasp Infestations

Knowing the signs of wasp infestations can help you take action before they become a bigger problem. Here are the key indicators that wasps have made your yard their home.

Increased wasp activity

One of the first signs of an infestation is increased wasp activity. If you notice wasps hovering low over your lawn, they might be searching for grubs. Frequent sightings around food and drink sources in your yard also suggest that wasps are using your yard as a food source.

Presence of nests

Keep an eye out for wasp nests around your property. These nests can be in the ground, trees, or crevices in structures. Signs of nest-building activities, such as wasps carrying materials or entering small openings, are clear indicators of a growing problem.

Physical damage to plants and structures

Wasps can cause noticeable damage to your yard and home. Look for chewed wood, tunnels in trees, and damaged grass. 

Grub infestations, which attract wasps like the blue-winged wasp and scoliid wasps, can lead to brown patches in your lawn. This damage can signal that wasps are not only present but actively feeding and nesting.

9 Effective Wasp Control Tips

When wasps make your lawn their playground, it's time to take action. Here's a mix of DIY methods and professional pest control options to help you reclaim your yard. From homemade traps to knowing when to call in the experts, we’ve got you covered.

1. Keep your yard clean

Remove fallen fruit, cover food and drinks during outdoor gatherings, and regularly dispose of trash. This reduces the food sources that attract wasps, making your yard less appealing to these pests.

2. Regular lawn care and water removal

Keep your grass trimmed and eliminate standing water to reduce wasp habitats. Wasps often search for grubs in tall grass and need water sources, so maintaining a well-groomed lawn can discourage them from settling in.

3. Seal cracks and crevices

Inspect your home for any cracks or crevices that could serve as entry points for wasps. Use caulk or weather stripping to seal these openings and prevent wasps from nesting inside your walls or attic.

4. Install screens on windows and doors

Ensure all windows and doors are fitted with screens to keep wasps out while allowing fresh air in. Repair any holes or tears in existing screens to maintain an effective barrier against these pests.

5. Set up wasp traps

Set up wasp traps away from home entrances and high-traffic areas in your yard. These traps attract wasps with bait, luring them in and preventing them from returning to their nests. Make sure to regularly empty and reset the traps to keep them effective.

6. Utilize homemade sprays

A simple soap and water mixture works wonders on small nests. Spray directly onto the nest during the cooler evening hours when wasps are less active. This method kills the wasps quickly and can be used repeatedly for new nests.

7. Use natural repellents

Create a vinegar and sugar mixture to deter indoor wasps. The strong smell of vinegar masks the scents that attract wasps, while the sugar lures them in, keeping them away from more sensitive areas of your home.

8. Plant wasp-repelling plants

Certain plants like mint, eucalyptus, and citronella naturally repel wasps. Plant these around your yard and garden to create a wasp-unfriendly environment.

9. Seek professional help

Sometimes, DIY methods aren’t enough, especially with large infestations or hard-to-reach nests. If you notice large numbers of wasps, multiple nests, or experience frequent stings, it’s time to call a pest control specialist. 

Professional services are equipped to handle extensive infestations safely and effectively. They can also access nests in tricky locations like under eaves, inside walls, or underground, which can be dangerous to handle on your own.
