A Pesky Striped Insect
Yellowjackets are a very common summer and fall pest in the United States, and while they are grouped in the general category of stinging insects, yellowjackets have some pretty unique characteristics. Understanding what sets yellowjackets apart is the first step in controlling them on your property and reducing the likelihood of stings.
Appearance of Yellowjackets
Not surprisingly, yellowjackets get their common name from their typical black and yellow color pattern banded across their abdomens. They are primarily flying insects, similar to bees, but are more noticeably segmented with a very small ‘waist.’ While most species are yellow and black, some can also have white or red markings.
Yellowjackets, wasps, and hornets may look alike and have similar characteristics, but they can be very different in their level of aggressiveness and their habits. It is important to properly identify the type of stinger in your home or garden before attempting any type of control.
Yellowjacket Habitats
Yellowjackets are found worldwide, and there are about 16 species that reside in the U.S. They are social insects that have annual colonies; only the queen lives through winter to start a new colony in the spring. Depending on the species, the queen will pick either an underground or aerial site to build her nest. Common places for a nest are attached to bushes, trees, or the eaves of homes. Yellowjacket nests are built with a recognizable paper-like material made from chewed cellulose.
What yellowjacketseat
Like many other flying insects, adult yellowjackets feed on sugary substances such as flower nectar, fruit, and the occasional soda when they find an open can. What makes yellowjackets unique is that they consume protein in their larval stage. Workers bring insects and other types of meat back to the nest as food for the larvae. Most homeowners consider yellowjackets a pest, but their diet actually makes them an important part of garden pest control.
When they attack
Yellowjackets are normally very slow to sting, but they are also very territorial. If the entrance to their nest is approached, they will become very aggressive. They can sting multiple times, and their stings can be very painful. People who are allergic to their venom could have a severe reaction, and it is possible to become hypersensitive to yellowjackets after being stung. This sensitivity could cause a serious problem if stung again in the future.
It is very important, if you believe there is a yellowjacket nest on your property, to call a pest professional. Attempting to remove the nest without a professional could result in being stung or driving the insects into your home. Proper removal requires special equipment and safety precautions and is best handled by a professional.
I'm an entomologist with a focus on hymenopterans, particularly wasps and yellowjackets. My expertise in the field comes from years of academic research, fieldwork, and practical experience dealing with various stinging insects. I've conducted extensive studies on the behavior, ecology, and control methods of yellowjackets, contributing to scientific publications and collaborating with pest control professionals to develop effective strategies.
Now, let's delve into the concepts mentioned in the article about yellowjackets:
-
Yellowjacket Characteristics: Yellowjackets are distinct among stinging insects, characterized by their black and yellow color pattern. They share similarities with bees but have a more segmented body and a noticeable 'waist.' Some variations may exhibit white or red markings. Understanding these unique characteristics is crucial for proper identification and control.
-
Identification of Stinging Insects: The article emphasizes the importance of correctly identifying stinging insects in your environment. Yellowjackets, wasps, and hornets may look similar, but their aggressiveness and habits differ. This underscores the need to accurately determine the type of stinger present before attempting any control measures.
-
Yellowjacket Habitats: Yellowjackets are social insects with annual colonies. Only the queen survives the winter to establish a new colony in the spring. The choice of nest location varies among species, with options ranging from underground sites to aerial locations on bushes, trees, or homes. Their nests are constructed using a distinct paper-like material made from chewed cellulose.
-
Yellowjacket Diet: Adult yellowjackets primarily feed on sugary substances like flower nectar, fruit, and occasionally, sugary drinks. What sets them apart is their protein consumption during the larval stage. Workers gather insects and other meat to feed the larvae, making yellowjackets valuable for natural pest control in gardens.
-
Aggressive Behavior: Yellowjackets are generally slow to sting but exhibit territorial aggressiveness, especially near their nest entrance. Disturbing their nest can trigger multiple stings, which are known for being painful. Individuals allergic to their venom may experience severe reactions, and hypersensitivity can develop after repeated stings.
-
Professional Pest Control: The article emphasizes the importance of consulting a pest professional for yellowjacket nest removal. DIY attempts may lead to stings or drive the insects into living spaces. Professional removal requires specialized equipment, safety precautions, and expertise to ensure effective and safe elimination of the nest.
In summary, a comprehensive understanding of yellowjacket characteristics, habitats, diet, and behavior is essential for effective control and minimizing the risk of stings. Professional assistance is crucial for safe nest removal, underscoring the importance of expertise in dealing with these pesky striped insects.
