- Overall these are an add-on from the builder to
1. increase sell-ability of their product.
and
2. give the Bug Guy ( Home Team Defense) a residual contract forever due to this system.
If you buy a house with this system and don't sign up for pest control - there's like a 1000% chance the installer of the tubes will come by and knock on your door to sell you pest control.
Do they work? In theory , not really.
Can they benefit? Better than not having them I suppose.
What happens to the fine amount of chemical being spraying into the insulation in which a spider is unlikely to be? not alot .
Will the Tubes last many years? Tubes are installed during construction.. a rip, a tear, or a kink to a very thin tube deems them useless inside your wall.
Will it stop bugs ( Spiders/ Scorpions) from coming inside your weeps holes, and up into the attic? No, the tubes are usually 100% surrounded by the insulation and there's a barrier and piece of ply wood in-between.
- IMO just make sure your getting 100% expected pest control service as normal, not a tech just spraying a tiny amount into these tubes. Bugs live on your entire property
Your first two points are correct. Of course it's meant to increase marketability as well as provide a residual contract. That's business. Doesn't mean anything one way or the other on the product working.
As I said before, it doesn't spray it into insulation. And isn't surrounded by insulation, either. Thankfully I was able to inspect mine during construction for any issues. Also, it doesn't claim to do half the other stuff you mentioned.
They spray all exterior entry points and your yard as part of the service and also provide interior service if you want it for the same price.
They do this plus the ports at the same price as several of my other quotes (and with the same chemicals). Just one anecdotal new build here that hasn't had any pest issues since they started coming.
