The pest tubes or "tubes in the wall" system was originally created by a company in Florida and then sold off to Centex which is now called "Home Team Pest Control" in the mid to late 1990's.
The entire system consists of small high pressure tubing with "laser slits" on 12" spacings that supposedly go through every lower wall in the entire home. These tubes then terminate at a "portal" on the outside of the home where the treatment is performed.
Here is how it works - a tank system containing 2 tanks - 1 with chemical and the other with compressed air (a scuba type tank) is used to apply and push the chemical through the tubes. The scuba tank pushes air at a rate of around 2000 PSI which pushes the chemical through the tubes and causes it to "spray" out of the laser slits in the tubes.
Basically, each tube is given a 15 second dose of chemical and then a 5-10 second blast with air. The chemical is usually permethrin or bifenthrin based. After treatment, the portal is closed off, and usually an outer perimeter spray or granules are then applied to keep other pests from migrating in.
Here are the problems with the "Tubes in the Wall system", and I know, because we were the first company in Texas to service this system -
1) The installations are eratic, and if there are any kinks in the tubes, or if the installers did not install it properly, such as the hose kinking in the corner of a room when it rounds the wall, that tube is useless beyond the point where it kinks. Also, staples to hold the tubing in place can be applied wrong and can crush the tube. This was a very common occurrence, and the number 1 problem that I found with installers.
2) Sometimes depending on the chemicals used, they gum up inside the tubes and render the tube useless. There is no way to replace this tube once it is gummed up or kinked.
3) If the tube is too long (over 50-60 feet), the air will not push the chemical hard enough because there is not enough pressure, and the chemical will either not make it to the end of the tube, or is basically drips out and forms a puddle. This can make a wet spot on walls, carpet, floors, etc.
4) The tubes in the walls system is only designed to keep bugs out of the walls. Treating inside the walls will do nothing for insects that do not infest walls, such as spiders, fleas, flying insects, etc. This system also does not need applications every 60-90 days, 1 time per year, or even every other year is more than sufficient.
As you can see, I am not a big fan of the Tubes in the Wall System. I would prefer to dust in the walls with a longer lasting Boric Acid based dust such as Borid, and dust through weep holes, electric switches, plumbing penetrations, etc. I think this method is much more effective and also has less troubleshooting involved.
With that said, unless you have a way of building a 2 tank system that can deliver air and push chemical, you will have to resort to old fashioned and more reliable ways of killing bugs. Or you could call Home Team Pest Control and pay them an outrageous amount of money to service your system. Most people just forget about it and resort to standard pest control techniques. It's great marketing and sounds like a good way to go, but with my experience, its overpriced and usually does not perform up to expectations.
Pestabs is a great product that will probably solve all general pest problems, and it's less than $10.00 per application. Its the same product that a lot of Pros use - Here is the link : http://www.epestsupply.com/product/PE...
Hope this helps.
