  • 1. Ant Management WEBINARFudd Graham, Janet Hurley, Dan Suiter, Karen Vail, Mike Merchant eXtension USDA/NIFA Auburn University, Texas A&M University, University of Georgia, University of Tennessee, Texas AgriLife Extension
  • 2. Ant ManagementManaging Problems with Pharaoh AntsDr. Michael Merchant,Texas AgriLife Extension ServiceProfessor and Extension Urban Entomologistm-merchant@tamu.edu
  • 3. IDENTIFYING ANTS Sometimes confused with other insects Pinched waist One or two pedicels (nodes) between thorax and abdomen Elbow joint in the antennae (except in some males)
  • 4. MICROSCOPE OR HAND LENS?  Hand lens OK for most pest ants
  • 5. BASIC ANT ANATOMY Thorax Petiole (nodes) { Gaster {
  • 6. BASIC ANT ANATOMY Petiole (nodes)
  • 7. PETIOLE SHAPE AND NUMBER Number of nodes used in identification 60X magnification
  • 8. PETIOLE (SINGLE, POINTED) Single node with peak 60X magnification
  • 9. POLYMORPHISM When ant workers of the same species vary in size and shape  Majors and minors minor workers major workers female reproductive
  • 10. OTHER CHARACTERS USED TOIDENTIFY ANTS Nesting sites Mound construction/ appearance Foraging behavior Defensive behavior
  • 11. RECOGNIZING REPRODUCTIVE ANTS Elbowed antennae Un-equal length wings Pinched waist
  • 12. PHARAOH ANTS Queen Worker Pharaoh ants
  • 13. CHALLENGES OF PHARAOH ANT CONTROL• Tramp species • Polygyne, synanthropic, easily transported• Rapid development time • 22-48 days (egg-adult)• Reproductive strategy • Nest division, rapid spread to new sites, not fussy about nesting sites (indoors and outdoors)• Difficult to control • Baits, sprays
  • 14. NESTING SITES Indoors  Walls  Cardboard boxes  Drawers  Storage areas  Follow electrical lines Indoor colonies frequently forage outside in warm season
  • 15. BAITS Use baits tested against Pharaoh ants such as  Advion Ant Bait Arenas  Maxforce Ant Bait Stations  (Sugar-based baits) Place where ants active but unreachable by children Avoid use of cleaning chemicals or insecticides around stations Store baits away from chemicals Handle with clean hands
  • 16. look along structural guidelines
  • 17. TIPS FOR BAITING Warmer times of year – bait outdoors Outdoors : monitor window sills, entrances and exits, water spigots, ac/heat units, attic vents, etc.
  • 18. RESIDUAL INSECTICIDES Avoid fast-acting sprays Photo by Alex Wild  Permethrin  Cyfluthrin  Deltamethrin  Bifenthrin Slow-acting, non-repellent sprays OK  Chlorfenapyr (Phantom) indoors  Fipronil (Termidor) outdoors

  • 39. ANTS Ants are the number 1 urban pest in the United States generating an estimated $1.7 billion annually for pest management professionals (Curl 2005) in Field, Klotz, Rust and Kupfer (PCT [Ant Control] on Target 3/26/2007) Curl, G. 2005. A strategic analysis of the U.S. structural pest control industry – The 2005 season. A survey of Pest Management Professionals in the U.S., Gary Curl, Specialty Products Consultants.
  • 40. WHY HAVE ANTS BECOME SUCH ADOMINANT PEST? Structures placed in ants’ habitat Society less tolerant Some tramp species more difficult to control Others? (Cooper 2004, PCT Ant Summit)

SANITATION/CULTURAL CONTROL Clean spills promptly Store food properly Remove waste reg. Clean waste cans Place dumpsters/cans away from school Fix leaks quickly Wipe trails with cleaner Trim vegetation Move mulch away Replace landscape timbers Remove debris that retains moisture Seal entry points
  • 69. CHEMICAL CONTROL Baits  Cracks and crevices where ants active  Sweet or protein baits (NOT oil for OHA)  Reduce food competition with bait  Do not apply fast-acting sprays near baits  Do not disturb ants foraging to baits
