WARNING: Deadly Asian Insects Have Now Been Confirmed In Wisconsin

One of the many advantages of living in Wisconsin over other states is that people don't have to worry too much about encountering dangerous creatures.

Of course, black bears and wolves are common, but they generally stay away from people unless provoked or protecting their young. You can also find venomous rattlesnakes and certain spiders like the brown recluse and black widow in the state, but thankfully, they remain rare.

However, things can change, and things we never worried about, or even knew about, can suddenly become a threat. A perfect example is when a potentially deadly invasive species is brought into Wisconsin, where it can then grow in numbers.

Unfortunately, that appears to be the case now, as a venomous insect imported into the country from Asia has been confirmed in Wisconsin.

Dangerous Asian Insect Confirmed In Wisconsin

The Asian needle ant, Brachyponera chinensis, is not new to the United States. Reports indicate that it was first introduced to the country in the 1930s via shipping. Although it's been in the U.S. since then, its population has now expanded to the point where it's found in multiple states, including Wisconsin, where outlier populations have been established.

Experts say that Asian needle ants are small, shiny ants that are typically dark brown to black, with lighter brown to orange-ish legs and mandibles. They have a slender body and a distinctive inability to cling to smooth surfaces like glass. Their stinger, which is used for defense, is also a lighter color than their body.

Asian needle ants are typically found in moist, damp areas both in natural environments and around human structures. They often nest in leaf litter, under stones or rotting logs, and in man-made structures like sprinkler systems or pavement crevices. They also forage in residential areas, parks, and urban environments, and have been known to enter homes searching for food.

So, like all ants, they are found where people are, and that could put people in danger.

How Are Asian Needle Ants Dangerous?

If you're wondering why there are concerns over little ants, it's because Asian needle ants are dangerous. Their stings are reportedly very painful, and that pain can persist for several hours. Furthermore, their stinger is fine and capable of piercing through clothing, which can lead to stings even if you wear protective gear.

If stung, there is a risk of an infection developing if the area is not cleaned properly. Even worse, in some individuals, a sting can trigger a potentially life-threatening allergic reaction called anaphylaxis.

Anaphylaxis is a severe allergic reaction that happens quickly after exposure to an allergen. It involves a whole-body reaction, affecting multiple systems, and can be triggered by insect stings, foods, medications, or other substances.

Symptoms of anaphylaxis develop quickly and can include:

• Respiratory problems (difficulty breathing, wheezing, swelling of the throat)
• Skin reactions (hives, itching, rash)
• Low blood pressure
• Gastrointestinal distress (nausea, vomiting, diarrhea)
• Dizziness, fainting, or loss of consciousness
• Swollen tongue or throat
• A weak and rapid pulse

Health officials say if you suspect anaphylaxis, do not wait for symptoms to improve; you should call 911 immediately.  Also, epinephrine should be administered if you have an epinephrine auto-injector (EpiPen) and know how to use it.

Thankfully, Asian needle ants are not aggressive like fire ants. However, they will sting if they feel trapped or disturbed, and their stinger is capable of piercing through clothing.
