Rasberry Crazy Ants (Tawny Crazy Ants) in Nevada

Rasberry crazy ants were first introduced to the public in Texas in 2002, and are also referred to as “tawny crazy ants.” They have since spread to the Las Vegas and Henderson areas and it is believed they may be displacing fire ants. Known for their erratic movements, rasberry crazy ants follow pheromone trails much like other ants. However, due to their very long legs and sporadic movements, they don’t “march” in a neat line like other ants. Rasberry crazy ants can kill grass, displace other insects and destroy electrical equipment, causing damage in urban and rural areas. 

Rasberry Crazy Ant (Tawny Crazy Ant) Habitat

Constructing large nests, typically near moisture, rasberry crazy ants will nest in any available gap and crevice. Nests are located in leaf debris, waste material, damp soil, and other protected habitats. Colonies are typically outdoors, although rasberry crazy ants will venture indoors to forage for meats and sweets. Nests have also been found in potted plants, stumps, and electrical equipment. Tending aphids and consuming their honeydew secretions, rasberry crazy ants also prey on live animals and scavenge from dead animals.
