Beware of this stinging, venomous, invasive ant species that is now present in Texas
A new invasive species of ants with venomous stings is present in 20 different U.S. states, including Texas, and is growing in population.
The Brachyponera chinensis, or the Asian needle ant, is an invasive species that can cause an allergic reaction in humans who are bit. Its name comes from its origin in China, Japan and Korea. The Asian needle ant made its way to the U.S. in 1932, probably in ships carrying plants and livestock.
An invasive species is one that is “likely to cause economic or environmental harm or harm to human health,” according to the U.S. Forest Service (USFS).
Here’s what you need to know.
What do Asian needle ants look like?
According to the USFS, these ants are small, shiny and darkish brown-black with orange-brown legs.
“There are other ant species in the Eastern United States that superficially resemble Asian needle ants, so it takes an experienced eye to positively identify them,” the USFS said.
Where do Asian needle ants live?
Asian needle ants live in wooded areas such as forests within logs, under stones or under mulch piles. But they will also invade populated areas near homes, businesses with leaf piles, woodchips, pavers or landscape timbers.
According to the Entomology department at North Carolina State, Asian needle ants try to avoid contact with humans, but will sting when pressured.
“The majority of stings from Asian needle ants occur when humans accidentally place their hands in nests or on ants, applying pressure to the ant that evokes a defensive sting,” according to NC State Entomology. “Because of this, it is wise to wear thick gloves when handling mulch, moving debris or placing one’s hand in dark areas that might be infested by Asian needle ants.”
What does an Asian needle ant bite feel like?
Both NC State and the USFS note how painful it is if the Asian needle ant stings you.
The sting is venomous and potentially fatal if you are allergic. Some people may have an allergic reaction, which can cause anaphylaxis.
“On average, [the Asian needle ant sting is] somewhat more likely to cause an allergic reaction than the venom in a honey bee’s sting,” according to NC State Entomology.
According to the USFS, mild hives and redness around the sting are commonly reported symptoms. The sting’s pain can also linger in and out for a few hours.
What should I do if I get bit by an Asian needle ant?
If you are prone to anaphylaxis when bit by other venomous insects, it is especially important to avoid Asian needle ant stings.
If you are bit and experience any of the following symptoms, you may be experiencing anaphylaxis and should seek medical attention right away:
Skin reactions, including hives, itching and flushed or pale skin
Low blood pressure (hypotension)
Constriction of the airway, wheezing, difficulty breathing
Swollen tongue or throat
Weak and rapid pulse
Nausea, vomiting, or diarrhea
Dizziness or fainting
Psychological symptoms, such as a feeling of impending doom
If you are not experiencing an allergic reaction, you can relieve the pain by,
Washing sting with soap and water
Applying an ice pack
Use benadryl or a topical allergy medication
