I got a response today, I don't see why I can't share it as it answers my questions.
Hi Matthew,
Sorry for the delayed response, we have been dealing with one problem after another recently regarding issues with our website and new regulations our company had to implement, which has taken up much of my time. I did get a chance to read your experience which does not reflect the average shelf life of Provent-a-mite. The minimum demonstrated shelf life is 10+ years (we have cans manufactured 20 years ago that are still effective). If a can is exposed to extreme conditions (heat or cold), it can affect the shelf life.
Our formula is unique and uses a different technical than other products, so the efficacy, residual effect, shelf life and toxicity are not the same as other products.
I do not know why your treatment seemed to have been ineffective. The can may have been exposed to conditions that could have degraded the formula. We have also had times when one did not seem to get successful results after a treatment, but then did another treatment with the same can and did eradicate the problem. You can test the efficacy by treating a surface and then place any type of insect or arthropod on the surface, if it dies in 5-15 minutes, the formula is still effective. If the can is still effective, but the results from a treatment were not, it would be due to treatment leaving an area that the mites could migrate through without touching the treated surface.
