In 1983, the manufacturers voluntarily cancelled its registered uses, with the exception of termite and fire ant control.

Adverse reactions to ants other than imported fire ants.

OBJECTIVE To identify ants other than Solenopsis invicta and Solenopsis richteri reported to cause adverse reactions in humans. DATA SOURCES We conducted a literature review to identify reports of medical reactions to ants other than S. invicta and S. richteri. Our review of medical and entomological literature on stinging ants was generated from MEDLINE and FORMIS, respectively, using the ke...
