What Are Cicada Killer Wasps?
Cicada killer wasps are not your average wasp. These insects can grow up to two inches long, making them one of the largest wasps you’ll find in North America. Here’s how you can identify them:
- Size: 1/8 to 2 inches long
- Color: Rust-colored head, thorax, and wings with orange legs and a black and yellow striped abdomen
- Resemblance: Often mistaken for yellow jackets or hornets
Despite their fearsome appearance, cicada killer wasps play a vital role in controlling the cicada population, which can damage young trees. However, their size and the loud buzzing noise they make can be intimidating.
- Males: Smaller, aggressive behavior, dive-bombing anything near their burrow (but they cannot sting)
- Females: Larger, capable of stinging but only if mishandled
Understanding the impact of cicada killer wasps is essential for maintaining a healthy lawn. Regular lawn and landscape maintenance can help prevent these wasps from becoming a problem.
The Life Cycle and Behavior of Cicada Killer Wasps
Understanding the life cycle of cicada killer wasps can help you manage their presence on your lawn. These wasps are most active in the summer when they mate and prepare their nests. After mating, the female will:
- Burrow: Create tunnels up to four feet deep
- Nesting: Build up to 20 chambers per burrow
- Feeding: Paralyze cicadas with her sting, place them in chambers, and lay eggs on them
When the egg hatches, the larva feeds on the cicada, growing strong before emerging as an adult wasp. While cicada killer wasps do not cause significant damage to your lawn, their burrowing activity can leave unsightly piles of dirt. Additionally, seeing a swarm of large wasps buzzing around can be unnerving, even if they pose little threat to humans.
To keep your lawn in top shape and reduce the chances of cicada killer wasps nesting, consider lawn mowing services as part of your regular lawn care routine.
Impact on Your Lawn
Cicada killer wasps are more of a nuisance than a destructive force. However, their burrows can create noticeable dirt piles on your lawn, making it look uneven and unkempt. If you’ve spent time and effort maintaining a lush, green lawn, the last thing you want is to see these wasps digging it up.
- Damage: Piles of dirt from burrowing
- Presence: Alarming to see wasps buzzing around, especially with children or pets
To keep cicada killer wasps at bay, you’ll need to use a combination of cultural and chemical control methods. For professional help, our lawn treatment services can ensure your lawn stays healthy and pest-free.
Cultural Control Methods for Cicada Killer Wasps
Cultural control is your first line of defense against cicada killer wasps. These insects prefer to burrow in bare or sparsely vegetated soil, so maintaining a thick, healthy lawn can help deter them from settling in your yard. Regular irrigation is crucial because cicada killer wasps do not like wet soil. By keeping your lawn well-watered, you make it less inviting for these wasps.
Cultural Control Tips:
- Regular Irrigation: Keep your lawn well-watered to discourage wasps from burrowing.
- Healthy Lawn Maintenance: Maintain a dense, thick lawn to leave fewer bare spots for wasps to create nests.
- Fertilization and Weed Control: A robust fertilization program and weed control services can prevent the bare soil that attracts cicada killers.
If your lawn is well-maintained, you’re less likely to have problems with cicada killer wasps. But if these methods aren’t enough, or if the wasps have already established themselves, it may be time to consider chemical control.
Chemical Control Options for Cicada Killer Wasps
When cultural controls aren’t enough, chemical control methods can effectively reduce cicada killer wasp populations. There are several products available that can help you manage these wasps:
- Sevin Dust (Bifenthrin): Sprinkle Sevin Dust around and inside the burrow holes. As wasps move in and out, they come into contact with the dust, which can help eliminate them.
- Hornet or Wasp Spray: Early in the morning, when the wasps are most active, use a hornet or wasp spray to target individual wasps as they exit their burrows. This method requires patience and precision but can be effective.
- Broad Insecticide Application: For more comprehensive control, consider a product like Cutter Backyard Bug Control. This insecticide is designed for use on your entire lawn and can provide up to 12 weeks of protection against cicada killer wasps.
When applying any chemical control, be sure to follow the instructions carefully to ensure effective and safe use.
