New Jersey is home to a diverse array of wasp species. These insects, often misunderstood, play a crucial role in our ecosystem. From pollination to pest control, wasps contribute significantly to maintaining ecological balance.
This guide will delve into the fascinating world of wasps in New Jersey, helping you identify them, understand their importance, and manage their presence safely.
Understanding Wasps in New Jersey
Wasps are a common sight in New Jersey, particularly during the warmer months. They are part of the Hymenoptera order, which also includes bees and ants. Wasps can be broadly categorized into two types: solitary and social.
Solitary wasps live alone and rarely build nests, while social wasps live in colonies and are often seen around their intricate nests. Understanding the behavior and characteristics of these wasps can help in managing them effectively and coexisting peacefully.
Common Wasp Species in New Jersey

New Jersey is home to a variety of wasp species. Each species has unique characteristics and behaviors.
One of the Most Common Species Is the Paper Wasp
Paper wasps are interesting insects known for their distinctive papery nests. These social creatures, though not as social as honeybees, live in colonies with a single queen and worker females. They are typically slender with black or brown bodies and yellow markings, and can be distinguished from bees by their narrow waists and long legs. Paper wasps are beneficial predators that help control insect populations, and while their sting can be painful, they are generally not aggressive unless their nest is disturbed.
Another Common Species Is The Yellow Jacket
Yellow jackets, common in New Jersey, are black and yellow striped wasps with a painful sting. They are social insects that build paper nests, often underground or in sheltered locations. Unlike honeybees, yellow jackets are attracted to sweet drinks and food, and can become a nuisance at picnics and outdoor gatherings. While they are important predators of other insects, their aggressive behavior and tendency to sting multiple times makes them unwelcome guests.

Bald Face Hornets in New Jersey

Bald faced hornets are a common sight in New Jersey. These large, black and white striped wasps are not true hornets, but are actually close relatives of yellow jackets. They build impressive, grey paper nests that can reach over a foot in diameter, often in trees, shrubs, or even on buildings. While bald faced hornets are beneficial predators of other insects, they can become defensive if their nest is disturbed. Unlike some wasps, they can sting multiple times.
Mud Dauber Wasps in New Jersey
Despite their intimidating name, Mud daubers are solitary wasps who are more interested in spiders than humans. These slender wasps, often black or metallic blue with thin waists, are easily identified by their mud-made nests. Unlike social wasps like hornets, each female builds her nest from mud, shaping it into tubes or clusters of cells. These nests are often found on walls, under eaves, or sheltered areas. Within these mud chambers, the female stuns spiders, stockpiling them as a food source for her developing young. Though they can sting, mud daubers are not aggressive, and their sting is more troublesome than dangerous for most people. In fact, by controlling spider populations, mud daubers can even be considered beneficial to have around.

Cicada Killer in New Jersey
Cicada killers are impressive solitary wasps that can be commonly spotted in New Jersey during the summer months. Despite their fierce name, these large wasps are not aggressive towards humans and their primary target is cicadas, which they paralyze with a sting and drag back to their underground burrows. The cicada serves as a food source for the developing cicada killer larvae. While their buzzing presence can be startling, cicada killers are actually beneficial insects as they help control cicada populations that can sometimes emerge in overwhelming numbers by the end of June and early July of each year. Many homeowners become concerned by their large size and the overwhelming number and usually rely on expirienced wasp exterminators to solve the problem.
European Hornets in New Jersey
European hornets, also known as giant hornets, are unwelcome guests in New Jersey. These large wasps, reaching up to 1.3 inches long, are the biggest stinging insects in the state. Their bodies are a distinctive brown with bold yellow stripes on the abdomen. Unlike their bald-faced hornet relatives, European hornets prefer to build their paper nests in sheltered locations, including attics, wall voids, or even under eaves of houses. While they are beneficial predators of other insects, European hornets can be aggressive if their nest is disturbed. Their sting is more painful than a bee sting, and unlike honeybees, European hornets can sting multiple times. If you spot a European hornet nest on your property, it’s best to call a pest control professional for safe removal.
Identifying and Locating Wasp Nests
Identifying wasp nests is the first step in wasp control. Nests can vary in size and location depending on the species.Common places for nests include trees, shrubs, and building eaves. Some wasps even nest in the ground or in cavities. Always approach nests with caution to avoid disturbing the wasps.
Preventing and Managing Wasp Populations
Preventing wasp infestations is easier than dealing with established colonies. Regular property inspections can help identify potential nesting sites. Sealing cracks and crevices in buildings can deter wasps from nesting. Maintaining a clean outdoor area can also discourage wasps. They are attracted to food sources like garbage and fallen fruit. There are natural deterrents that can be used to repel wasps. These include essential oils like peppermint and clove.
However, if a nest is found, it’s important to act carefully. Disturbing a nest can provoke wasps and lead to stings.
Here are some tips for managing wasp populations:
• Regularly inspect your property for nests
• Seal potential nesting sites in buildings
• Keep outdoor areas clean and free of food sources
• If a nest is found, approach with caution or consider professional help
When to Call a Professional Wasp Exterminator
While some wasp issues can be managed, others require professional help. If a nest is large or in a hard-to-reach area, it’s best to call an exterminator. Professionals have the right tools and protective gear to safely remove nests. They can also identify the wasp species and provide tailored control methods. Remember, attempting to remove a wasp nest without proper training can be dangerous.
Safe Wasp Control and Removal Tips
When dealing with wasps, safety should be your top priority. Avoid wearing bright colors or floral prints, as these can attract wasps. If a wasp approaches you, stay calm and still. Swatting at it may provoke an attack. For minor infestations, consider using a wasp trap. These can be bought or made at home. Remember, if you’re unsure or uncomfortable dealing with wasps, it’s best to call a professional.
Conclusion: Coexisting with Wasps
Wasps in New Jersey are more than just a nuisance. They are an integral part of the ecosystem, providing valuable services like pest control and pollination. However, their presence can be problematic when they nest too close to human habitats. In such cases, safe wasp control methods should be employed.
Remember, it’s important to respect these creatures and their role in nature. Avoid harming them unless they pose a direct threat. With understanding and proper management, we can coexist with wasps, appreciating their contribution to our environment while keeping our homes and gardens safe.
