  • Elbowed antennae

  • Dissimilar wing size

Termite Queen

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

Typical Subterranean Termite Post Construction

Treatment Process – Drilling, Ditching and Foaming.


Slide25 l.jpg

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.


Slide28 l.jpg

Injection of chemical below pad with 4 hole nozzle tip


Slide29 l.jpg

Filling of holes with rubber bullet and then cement calking.


Slide30 l.jpg

Bullet plugs are tapped 1 inch into hole with drill bit


Slide31 l.jpg

Hole is filled in with caulking compound


Slide32 l.jpg

Ditch all areas outside of foundation wall

and treat with termiticide.


Slide33 l.jpg

Injection of chemical into and below ditch


Slide34 l.jpg

Ditched area is filled with recommened amount of chemical


Slide35 l.jpg

Use a foam machine to inject termiticide into

bathroom water lines and any suspicious outside

wall baseboard


Slide36 l.jpg

Hand injection of foam

into wall

  • 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 l.jpg

  • Disadvantages of a Chemical Treatment

  • Environmental impact?

  • Tends to be invasive with the hole drilling.


Slide39 l.jpg

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)
