Termite and insect infestation

  1. 1. ST RUCT URAL P ST CONT E ROL (T ermite and Insect Infestation) By: Karlo Bauzon Arjay Garlan 1
  2. 2. Common Wood Destroying Insects Termites Carpenter Ants Powderpost Beetles Longhorn Beetles Flatheaded Borers Wood-boring Weevils
  3. 3. Termites Major destroyers of wood and wood product materials. Normally associated with buildings, but can also infest wood that has been stored for some time. There are three basic kinds of termites: Subterranean Dampwood Drywood
  4. 4. Isoptera (termites) [social insects, winged reproductives with both wings same size and membranous; straight or curved antennae consists of beadlike segments; abdomen broadly joined to thorax; no cerci; chewing mouthparts]
  5. 5. Termites are sometimes called “white ants” because they are ant-like in form. Termites differ in antenna form and having a broad waist. Ant or Termite? Figure 3-5
  6. 6. Subterranean termite colonies live in the soil from which they construct exploratory tubes in search of wood.
  7. 7. Termite Swarming is usually the first evidence of an infestation noticed by most people.
  8. 8. Drywood Termites Can live in dry, sound wood Usually tropical and subtropical Kick out characteristic fecal pellets Subterranean (left), Drywood (right)

  10. 10. Carpenter Ants Camponotus Figure 3-9
  11. 11. Carpenter Ants build nests in wood, they don’t eat it!
  12. 12. Carpenter Ant Damage Carpenter ants need water Usually build nests in damp or partially rotted wood, but can extend their nests into sound wood Keep lumber dry and properly stacked.

  17. 17. Anobiid powderpost beetles: Prefer old woods, 10-20 years old! Attack hardwoods and softwoods including maple Require 13% to 30% moisture
  18. 18. Wood-boring weevil, Hexarthum: Frass looks like powderpost beetles Attack hardwoods, including maple Require high wood moistures, often wet!
  19. 19. Wood-boring Beetle Management Detect early! (regularly inspect powder) Keep lumber at less than 5% moisture Keep lumber off of moist floors or ground Resaw to remove sapwood Don’t purchase infested lumber & destroy lumber that becomes infested Fumigate high cost lumber

  21. 21. WHAT IS STRUCTURAL PEST CONTROL ?  Definition:    Contain and control the condition of household and wood destroying pests which invade households, other structures and their contents Conduct Inspections Identify infestations  write reports, make recommendations, submit bids and estimates 21
  22. 22. LICENSE CLASSIFICATION The SPCB issues licenses in three specialties or branches….    Branch I Branch II Branch III - Fumigation General Pest Termite Control 22

  34. 34. LICENSES Operator  An operator may:     own or qualify a company identify pests negotiate contracts apply pesticide 34
  35. 35. LICENSES Field Representative  A licensed Field Representative may:    identify pests negotiate contract apply pesticide 35
  36. 36. LICENSES Applicator  A licensed Applicator may:   Apply pesticides in Branch II & III Fumigants can only be applied by Operators and Field Representative. 36
