  2. Urban Entomology Insects that Live With Us Sources of Help • Cooperative Extension (Extension) • Information, pamphlets, identifications • Lawn Maintenance Operations • Pest Control Operators (PCOs) • “Exterminators” • Deal with household/stored product pests • Deal with structural pests

  3. Not all ants are pests! Knowledge Can be a Key Urban Entomology Insects that Live With Us

  4. Urban Entomology Insects that Live With Us Structural Pests • Attack our homes, furnishings, out-buildings • Termites • Carpenter ants • Powderpost beetles

  5. Termites • Most important structural pest group • $1-3 billion/year in US • More common in warm/humid situations • Feed on cellulose - chief substance of wood Urban Entomology Insects that Live With Us

  6. Termites are Social Insects • Division of labor • Specific reproductives - most are “workers” • Termites • Reproductives • Soldiers • workers Urban Entomology Insects that Live With Us

  7. Urban Entomology Insects that Live With Us Termites Eat Wood but cannot digest it! Gut symbionts

  8. Urban Entomology Insects that Live With Us Termites are not born with internal symbionts Food is regurgitated and feed to nymphs Proctodeal Feeding

  9. Urban Entomology Insects that Live With Us Termites feed on cellulose

  10. Urban Entomology Insects that Live With Us Dampwood (Dry-) Larger Do not require soil contact Dark in color Common in western WA Types of Termites • Subterranean • Small • Require contact with soil (moisture) • White or cream in color • Common in and out of doors • More common in eastern WA
