Water-Resistant Bait Could Deliver Much-Needed Improvement in Pest Ant Control

Red imported fire ants

The red imported fire ant (Solenopsis invicta) and the little fire ant (Wasmannia auropunctata) are just two species of invasive ants that have thrived since their introduction to the U.S. The former has spread through much of the southeastern United States, while the latter has become widespread on the Big Island of Hawaii. In both […]

You’ve Got Ants: New 10-Minute Test Kit Detects Red Imported Fire Ants

The red imported fire ant (Solenopsis invicta) is an invasive species from South America that is damaging to agriculture and wildlife and known for its painful, venomous sting. That venom, however, is now a promising tool for entomological researchers in fighting back against S. invicta and limiting its spread. Throughout the southeastern United States, shipments […]

Compounds from Poison Frogs May be Used to Control Fire Ants

USDA scientists and their collaborators have found that naturally-occurring compounds that are found on the skin of certain poison frogs can incapacitate and kill fire ants. The red imported fire ant (Solenopsis invicta) damages crops, devastates small animal populations, and inflicts painful stings to livestock and to humans. To determine whether poison-frog alkaloids would kill […]

Each year in the United States, fire ants cost $7 billion for control, damage repair, and medical care. They infest millions of acres in urban, agricultural, wildlife, recreational and industrial areas. In order to combat the the red imported fire ant, scientists at the USDA’s Agricultural Research Service are studying pheromones that are secreted by […]

Using Flies to Reduce Fire Ant Populations

In a previous article, we showed how “Chinese Wasps are Taking on the Emerald Ash Borer” as scientists in Michigan introduced wasps from Asia in order to control the invasive and damaging emerald ash borer (EAB). The tiny wasps lay eggs in or on the ash borer larvae, and when the eggs hatch the wasp […]
