  • Activity: Known for its erratic, rapid movements
  • Preferred Climate: Warm, humid and dry
  • Defense: Bites then releases an acidic liquid that causes burning sensation
  • Cautions: Burning sensation if bit, see previous
  • Home Invasion: Will find way into home or can be transported by plants into home. Sets up multiple nests making it hard to control. On outside nests have little to no mounds and can be difficult to identify harborage points. Base of trees, foundations, under mulch or vegetation are most common harborage points outdoors. Will forage far for food so much track to harborage point to get to source. This can be difficult due to their random movements.
