  • colonies
  • Fire ants are social creatures with defined responsibilities in their colonies. (pestdefense.com)
  • Trophallaxis between individual worker ants and the toxicant load in dead and live Argentine ants (Linepithema humile) in colonies exposed to fipronil and hydramethylnon experimental baits were examined using accelerator mass spectrometry (AMS). (osti.gov)
  • Resurgence of polygynous ant colonies treated with hydramethylnon baits may be explained by queen survival resulting from sublethal doses due to a slowing of trophallaxis throughout the colony. (osti.gov)
  • swarm
  • Disturb a fire ant mound and they will swarm out by the hundreds to sting any person or animal perceived as a threat. (pestdefense.com)
  • queens
  • Dead workers and queens contained significantly more hydramethylnon (122.7 and 22.4 amol/μg ant, respectively) than did live workers and queens (96.3 and 10.4 amol/μg ant, respectively). (osti.gov)
  • Dead workers had significantly more fipronil (420.3 amol/μg ant) than did live workers (208.5 amol/μg ant), but dead and live queens had equal fipronil levels (59.5 and 54.3 amol/μg ant, respectively). (osti.gov)
  • large
  • Depending on how long the fire ants have been nested in your yard, the ant hill could be quite large and easy to spot. (ehow.com)
