2. Research and extension priorities for ant management Identification/Education Management personnel/ technicians/homeowners

3. Identification/biology/seasonal applications 1. Control of swarmers 2. Ants in winter months

4. Velvety tree ants Liometopum occidentale L. luctuosum

5. Large infestations

6. Research: Velvety tree ants Biology Behavior Distribution Management

7. Odorous house ant: 3 mm Velvety tree ant, L. occidentale: 2.5-5.5 mm Velvety tree ant, (pine tree ant) L. luctuosum: 2.5-4.5 mm

8. Odorous House Ants Tapinoma sessile Research: WDO or nuisance Natural habitats Chemical/cultural management

9. Pavement ants Tetramorium caespitum Tetramorium sp. E

10. Research: Seasonal Control Winged forms emerging in structures Slab construction Activity in winter months

11. Moisture/cornfield ants Lasius spp.

12. Research: Species: WDO/nuisance Management with removal of wood? Injection techniques for buried wood?

14. Carpenter ants Camponotus spp.

15. Research: Seasonal management Reproductives in structures in winter Wall injection at emerging sites vs full drill/inject treatment with liquid or dust

16. December/January

17. Research: (continued) Spot/partial treatment vs full perimeter sprays Label directions: ? up and ? feet out Equipment: power vs hand held

19. Baits

20. Use of baits Labor intensive: seasonal-foragers only Transfer of material Combination with other treatments Problem: Competition with natural foods or bait acceptance

21. Inspections: More emphasis on inspections: Initial plus follow-up Replace regular service calls with inspections Education of clients Change is good
