Cicada killer wasps are a common nuisance during the summer months, particularly in areas with high cicada populations. These wasps are known for their large size and painful stings, which can be a concern for people who spend time outdoors. According to experts at Yale University, cicada killer wasps are generally non-aggressive and only sting in defense of themselves or their nests. However, their presence can still be a problem for many people. In this article, we will explore the tips and strategies provided by Yale experts on how to stop cicada killer wasps.
Understanding Cicada Killer Wasps
Before we dive into the tips on how to stop cicada killer wasps, it’s essential to understand their behavior and biology. Cicada killer wasps are solitary wasps that belong to the family Sphecidae. They are typically large, with some species reaching lengths of up to 2 inches. These wasps are known for their distinctive black and yellow or brown coloration, and they are often mistaken for honeybees or yellowjackets. Cicada killer wasps are predators that feed on cicadas, which they use to feed their young. They are generally non-aggressive and only sting in defense of themselves or their nests.
Cicada Killer Wasp Life Cycle
Understanding the life cycle of cicada killer wasps is crucial in developing effective strategies to stop them. The life cycle of these wasps typically begins in the spring when the female wasp emerges from her winter hiding place. She then begins to search for a suitable location to build her nest, which is usually in a sandy or loose soil area. The female wasp will dig a burrow and lay her eggs inside, providing each egg with a cicada to feed on. The eggs will hatch into larvae, which will feed on the cicada and eventually pupate. The adult wasps will emerge from the nest in late summer, and the cycle will begin again.
| Cicada Killer Wasp Stage | Duration |
|---|---|
| Egg | 3-4 days |
| Larva | 10-14 days |
| Pupa | 14-21 days |
| Adult | 30-60 days |
Yale Expert Tips on How to Stop Cicada Killer Wasps
Now that we have a better understanding of cicada killer wasps and their life cycle, let’s explore the tips and strategies provided by Yale experts on how to stop them. According to these experts, the most effective way to stop cicada killer wasps is to target their nests and prevent them from building new ones. Here are some tips on how to do this:
Seal All Entry Points
Cicada killer wasps can enter your yard or home through small cracks and crevices. To prevent this, make sure to seal all entry points, including cracks in the foundation, walls, and roof. Use caulk or sealant to fill in any gaps or holes, and install door sweeps or weatherstripping to seal any openings around doors and windows.
Remove Food Sources
Cicada killer wasps are attracted to cicadas, which are their primary food source. To reduce the attractiveness of your yard to these wasps, remove any cicada-infested trees or plants. You can also use insecticides to control cicada populations, but be sure to follow all label instructions and take necessary precautions to avoid harming other beneficial insects.
Use Insecticides
Insecticides can be an effective way to control cicada killer wasp populations. However, it’s essential to use them judiciously and follow all label instructions. According to Yale experts, it’s best to use a combination of insecticides that target both the adult wasps and their nests. Some effective insecticides for controlling cicada killer wasps include pyrethrin, permethrin, and deltamethrin.
| Insecticide | Active Ingredient | Target |
|---|---|---|
| Pyrethrin | Pyrethrin | Adult wasps |
| Permethrin | Permethrin | Nests and adult wasps |
| Deltamethrin | Deltamethrin | Nests and adult wasps |
