Invasive Species Making Their Mark Across the United States

The National Pest Management Association (NPMA) Shares Top 5 List of Invasive Pests

FAIRFAX, VA (October 28, 2019) – Invasive species are on the move across the U.S., causing property and agricultural damage, and even presenting new health threats to Americans. The National Pest Management Association (NPMA) identified the top five species spreading across the U.S. and what people can do to prevent or eliminate these pests.

“Invasive species are particularly problematic because they have no known predators in the environments they invade and can multiply and spread rather quickly,” says Cindy Mannes, vice president of public affairs for NPMA. “These species can cause millions of dollars in crop and property damage each year and public awareness and help is needed in order to help stop the spread of these pests.”  

Brown Marmorated Stink Bugs

First arriving in 1996, brown marmorated stink bugs are native to Asia but are now found in 44 states across the U.S. Stink bugs release a notoriously unpleasant odor when crushed, hence their name. To keep this bug out of your home, patch holes in door and window screens and vacuum up any bugs found inside the house.

Asian Long-horned Ticks

First spotted in 2017, the Asian long-horned tick also came to the U.S. from Asia, where it is known to transmit deadly diseases to both livestock and humans. This tick has been known to carry bacteria and pathogens associated with diseases such as Lyme disease, Japanese spotted fever and SFTS (Severe Fever with Thrombocytopenia Syndrome). To protect against ticks, use insect repellent containing at least 20 percent DEET, wear long clothing when possible, and perform tick checks after spending time in wooded or overgrown, grassy areas.

Spotted Lanternflies

Spotted lanternflies were initially reported in Pennsylvania in 2014 and have subsequently spread to New Jersey, Delaware, Virginia, New York, Connecticut and Massachusetts. These pests pose a significant threat to various agricultural industries as they feed on the sap within many trees and plants. They also lay egg masses on trees, rocks and outdoor furniture. Contact your local Department of Agriculture to report a sighting and any migration of this invasive species.

Red Imported Fire Ants (RIFA)

Red imported fire ants (RIFA) were first spotted in Alabama in 1933, and are now found throughout the southern and western U.S. They will attack humans who disturb or threaten their nest, biting and stinging their victims. To protect against these invasive ants, seal all structural cracks and crevices to keep them from gaining entry. 

Formosan Termites

The Formosan termite is originally from China but can now be found across the southern United States. These destructive pests aggressively chew through wood, flooring and wallpaper and are the most destructive of the 2,000 known termite species. Homeowners living in the southern U.S. are strongly encouraged to have annual professional termite inspections to help protect against termite damage. 

NPMA recommends anyone who suspects an invasive pest infestation immediately contact a licensed pest control professional. A trained professional can identify the species and recommend a course of action to deal with the infestation before it becomes a greater problem.
