Presentation Transcript
slide3

Broad waist

  • Beaded antennae
  • Similar wing size
  • Constricted waist
  • Elbowed antennae
  • Dissimilar wing size
slide22

Chemical Treatments

  • Repellents: mostly used as pretreatments (before
  • pad is poured)
  • Talstar - bifenthrin
  • Demon – cypermethrin
  • Various others – permethrin
  • Non-repellent: posttreatments (after construction)
  • Phantom – chlorfenapyr
  • Termidor – fipronil
  • Premise – imidicloprid
slide23

Typical Subterranean Termite Post Construction

Treatment Process – Drilling, Ditching and Foaming.

slide25

Where trenching can’t be done in soil such as

concrete pads up against the foundation, like in patios,

entry ways and garages, holes need to be drilled to the

soil and treated.

slide35

Use a foam machine to inject termiticide into

bathroom water lines and any suspicious outside

wall baseboard

slide37

Advantages of a Typical Chemical Treatment

  • Termites are not repelled by a typical insecticide
  • barrier such as Termidor or Premise.
  • 2. They pick up the chemical without
  • detecting it and carry it back to the nest.
  • 3. At the nest it is fed to the other workers
  • and the queen.
  • 4. Chemical treatments are less expensive than baits.
  • 5. Chemical treatments are proven to last 5 years.
slide38

Disadvantages of a Chemical Treatment

  • Environmental impact?
  • Tends to be invasive with the hole drilling.
slide39

Termite Baits

Exterra – diflubenzuron (chitin synthesis inhibitor)

Recruit II – hexaflumuron

Subterfuge – hydramethylnon (can be placed in

ground without monitoring – check at one month

and then every three months.

Firstline - sulfuramid (intended for above ground)

Firstline GT – in ground in specific areas

Advanced Compressed Termite Bait – has a TIC

on top (diflubenzuron)

slide51

Identification of Drywood Termites

  • Character of reproductives.
  • a. wing venation
  • b. antennal segments
  • 2. Character of soldiers.
  • a. shape of head.
  • b. mandibles.
  • 3. Presence of fecal pellets.
