Dealing With Tubes In The Wall ‘Blow Back’

A common problem in servicing pest tubes systems is blow back. Air and pressurized liquids are shot from specialty machines into the system and suppose to come out tiny little laser slits in the target area as a fine mist. Unfortunately this does not always happen and the liquid, still under pressure comes spewing back out the treatment tube. It’s very tempting to just walk away from a portal or some tubes and say, “oh well that one has a kink and can’t be treated.” However in most cases if you work it just right you can ‘clear the lines’ and have a successful shot getting the product to where it’s needed and giving the customer what they’ve paid for.

Take a minute if you would and watch this short video on how to deal with ‘blow back’ and hopefully this will allow you to have more successful treatments. Not every tube will cooperate but you’re definitely going to be able to get a few stubborn ones to take and that may mean the difference between pest problems or not for your client.

    So how well do the tubes in the wall work?

  • For some of our customers it is fine but others wish they never spent the money when building. Most are either disappointed or at least surprised when I tell them it DOES NOT run the length of the home covering every square inch.

    If I were to ever build a new home for me– I would have it installed.
