The First 100% Sustainable Non-Pesticide Termite Treatment in Texas

TERM Particle Barrier Package

Polyguard Products, of Ennis, TX, has introduced TERM™ Particle Barrier to keep termites out of Texas homes, schools, and other sensitive structures. 

TERM Particle Barrier is 100% sustainable.  Texas pest control regulators class it as a “barrier”.  EPA classes it as a “device”.   The TERM Particle Barrier is the first and only non-pesticide termite treatment for existing structures available in Texas.

The TERM Particle Barrier concept is easy to understand.  Tests by Polyguard and by Texas A&M have shown that the two most common termite species in Texas (Coptotermes formosanus and Reticulitermes flavipes) are unable to penetrate the sized stone particles which make up the TERM Barrier. The particles are too large for termites to move aside, and too close together for termites to crawl between.  Termites simply go elsewhere for their food.

The TERM Particle Barrier was developed by Bryan Springer, a Galveston area Pest Management Professional.  After hearing how particle barriers were being used across Hawaii and Australia for Termite Control, Bryan set out to develop a barrier which would block the Coptotermes formosanus and Reticulitermes flavipes species in Texas.  In 2005, after preliminary testing by Texas A&M, Bryan installed the new barrier on a number of termite infested homes along the Texas Gulf Coast.  The field installations were successful and Termite Prevention occured.  Further testing of the particle barrier by Texas A&M resulted in publication of a paper in September, 2013.

There are three common entry points in existing structures where the TERM Termite Particle Barrier can block termites:

  • Exposed perimeter area where soil meets vertical concrete. 
  • Bath traps, which are 1-2 ft 2 openings in slabs where termites enter directly from underneath the house.
  • Plumbing penetrations, where water lines and drains enter the structure through the slab.  Untreated penetrations usually have sufficient space between the pipes and concrete for termite entry from underneath.

There are other termite entry points besides perimeters, bath traps, and penetrations.  However, treatment of these three areas with TERM Particle Barrier should, in most instances, significantly reduce any need for chemical treatment of the structure.


Plumbing Penetrations Plumbing Penetration Treatment Using Polyguard's TERM Particle Barrier

Plumbing penetrations are a major entry point for termites, because pipe coming up through the slab is rarely tight against the concrete.  Especially with hot water lines, which expand and contract as they heat and cool, which causes more tiny gaps to open between the pipe and the concrete.  Research has shown that a gap of .018” is enough for a termite to crawl through.

For your pest management professional to treat plumbing penetrations in an existing structure, it may be necessary to remove a portion of the interior wall in order to gain access to the penetrations.  So this solution is somewhat more complex in scope than the perimeter or bath trap treatments.

Taking the Next Step

If you are interested in the TERM Particle Barrier, ask your licensed Pest Management Professional.  In the event that your PMP is unfamiliar with the particle barrier, (Polyguard is just introducing it to Pest Management Professionals, at the same time we are introducing it to you) call or email Polyguard Contact Us and we will arrange to familiarize your PMP with the TERM Particle Barrier.

  • TERM™ Particle Barrier was developed by Bryan Springer, a Galveston area PMP, and tested by Texas A&M (Particle Barrier Test)
  • In 2005, Bryan installed TERM Particle Barrier on a number of infested Gulf Coast homes; as of December 2013, all are clear of termites.
  • Particle barriers for termites have been standard building practice in Hawaii and Australia for over 25 years.
  • The particles are sorted and sized to block the two dominant Texas termite species (Reticulitermes flavipes and Coptotermes formosanus). The sized particles are too big for the termites to move aside, and too small for termites to squeeze between.
