Cicada Killer Wasps

Cicada killers, also known scientifically as Sphecius speciosus, are a type of solitary wasp that is commonly found in North America. These large, striking insects are named for their behavior of hunting cicadas, which they use as a food source for their developing larvae. Here is an overview of cicada killers:

• Physical Characteristics: Cicada killers are among the largest wasps in North America, with females measuring around 1.5 to 2 inches (3.8 to 5 centimeters) in length, while males are slightly smaller. They have a distinctive appearance, featuring black bodies with yellow markings, particularly on the abdomen and face. Their wings are clear and smoky-colored, making them easy to distinguish from other wasp species.
• Behavior and Lifecycle: Cicada killers are solitary wasps, which means they do not form colonies like social wasps such as yellow jackets or hornets. The females are responsible for hunting cicadas, which they paralyze using their stingers. Once a cicada is paralyzed, the female cicada killer carries it back to her underground burrow, where she lays a single egg on the cicada's body. The larva that hatches from the egg then feeds on the cicada, eventually pupating and emerging as an adult the following summer.
• Nesting: Cicada killers are known for their impressive digging abilities. They create burrows in loose, sandy soil, often in sunny areas. These burrows can be up to a foot (30 centimeters) deep and have multiple branching tunnels. The female cicada killer provisions each tunnel with a paralyzed cicada, laying an egg on one of them before sealing the tunnel. The provisioning and nesting behavior is crucial for the survival and development of their offspring.
• Territorial Nature: Male cicada killers are territorial and establish areas where they defend against other males. They do not sting and are primarily focused on patrolling their territory and seeking out females for mating. Female cicada killers can sting if they feel threatened or provoked, but they are not aggressive toward humans and typically avoid confrontation.
• Benefits and Ecological Role: While cicada killers may appear intimidating due to their size, they are generally not considered pests. In fact, they play a beneficial role in controlling cicada populations, which can sometimes reach damaging levels for trees and crops. Cicada killers are a natural form of biological pest control.
• Seasonal Activity: Cicada killers are typically active during the summer months when cicadas are abundant. They have a relatively short adult lifespan, with most individuals living for only a few weeks.

Cicada killers are fascinating insects with distinctive characteristics and behaviors. They are valuable for their role in regulating cicada populations and have a relatively low impact on human activities. While they may appear intimidating, they are not aggressive toward humans unless directly provoked, making them an intriguing and ecologically important part of North America's insect fauna.

How To Get Rid Of Cicada Killer Wasps

Managing cicada killer wasps, also known as Sphecius speciosus, should be approached with caution and an understanding of their ecological importance. Here's a guide on how to address a cicada killer wasp issue if it becomes necessary:

Determine the Extent of the Infestation: Before taking any action, assess the size and location of the cicada killer wasp nests. If the infestation is small and poses no immediate threat, consider leaving them alone, as these insects play a beneficial role in controlling cicada populations.

Non-Lethal Deterrents: If the cicada killers are nesting in an area where you or your family frequent, consider implementing non-lethal deterrents to discourage their presence:

• Heavy Foot Traffic: Simply walking near the nest entrances can disrupt the cicada killers' activities and may cause them to relocate.
• Water Hose: Spraying a strong stream of water into the burrow entrances can temporarily discourage the wasps and disrupt their nesting.

Protective Clothing and Caution: If you must approach the nest, wear protective clothing, including long sleeves, pants, gloves, and a veil or face shield to avoid stings. Move slowly and calmly, as cicada killers are generally not aggressive unless provoked.

Wait for Natural Lifecycle Completion: Cicada killers are active for a relatively short period during the summer months. Their lifecycle typically lasts only a few weeks. If possible, you may choose to wait until they naturally die off, and their nests are abandoned.

Relocation or Nest Removal: If cicada killers are nesting in an area where their presence is a significant concern (e.g., near a high-traffic area), consider relocating or removing the nests. Here's how:

• Relocation: You can carefully dig up the nest burrows and move them to a less populated area. Be sure to handle the nests gently to avoid damaging them or injuring the wasps.
• Nest Removal: If you decide to remove the nests, wait until evening when the wasps are less active. Use a shovel to carefully dig up the nest, ensuring you get all the tunnels. You can then dispose of the nests by sealing them in a plastic bag and placing them in the trash. Be cautious during this process to avoid stings.

Professional Pest Control: If you are uncomfortable dealing with cicada killer wasps or the infestation is extensive, consider hiring a professional pest control service. They have the expertise and equipment to manage the situation safely.

Remember that cicada killers are generally beneficial insects that contribute to natural pest control. If their presence is not causing significant problems, it's often best to coexist with them and appreciate their role in the ecosystem. Always exercise caution when attempting to remove or relocate nests and prioritize your safety.
