These ants kill songbirds and poultry, small mammals including house pets, squirrels and even larger mammals such as deer, cattle and horses.The ants kill chickens via asphyxia by crawling into their nasal passages. In addition to the physical danger posed by the ants, they have a large affinity for climbing onto and into electronics and shorting lines causing extensive financial damage.
Humans are playing a key role in assisting with the migration of these pests. These ants show likelihood of being transported through movement of almost any infested container or material. The movement of garbage, yard debris,bags or loads of compost, potted plants, and bales of hay, can transport these ant colonies by truck, railroad, and airplane. Several very large name home improvement chains that sell plants have reportedly had problems.
Rasberry crazy ants eat almost anything; they are omnivorous. They have multiple queens and are outsmarting attempts to eradicate them. There are no effective products readily available to the consumer to manage the ants, so you should identify the ants; and, if rasberry ants, immediately treated by a professional.
Currently, the ants have been identified in south and central Texas. However, the ant has the potential to spread well beyond the current range in coastal Texas. However, because this is a semi-tropical ant, it is anticipated potential northern distribution will be limited by cooler weather conditions.
