Preventive Mite Treatment?

[Evenstar]

If by "preventive" (and thank you for spelling it correctly) you mean treat your enclosures and racks regularly even when you don't have an outbreak then no, I don't do it. I do treat anything that comes into QT as being infested until proven otherwise, so the enclosures, hides, and substrate get PAM'ed the day before arrival so they have plenty of time to dry. The snake gets wiped down with paper towels soaked in Reptile Spray as soon as it is unboxed so if it does have mites I'll know immediately.

This. QT and treating while in QT is my only preventative measure. My collection is healthy and mite free and is kept mite free with just this

I use it as a preventative if I take my snakes to a show, or bring snakes home. I do not spray the inside of the tubs for the reasons of your cons, but I do spray the racks. I take all the snakes out of their tubs while I spray. Let it dry and put them back in. Mights are a nightmare and I don't want to deal with 60+ snakes being infected.

These are the things I do too. I prefer using just Reptile Spray (I get it from Reptile Basics - it is the Natural Remedies brand) and do try to avoid PAM unless, heaven forbid, a problem should arise. I wipe down tubs and hides the day before new arrivals come and use only paper towels as substrate. I also wipe down all new acquisitions with the Spray. I've never had mites in my collection and, knock on wood, I plan not to.

I even had one snake that had mites when purchased at an expo. Fortunately, I was prepared and had Reptile Spray with me so I was able to treat her in the hotel room that night. We didn't come home with a single bugger and my collection has stayed mite free.

I don't use any other preventative treatment for the same reasons as your cons. In my opinion, if careful q/t is practiced and preventive treatment is done upon arrival, then further preventive treatment shouldn't be necessary (with the exception of some larger breeding facilities that may not practice strict q/t for logistical reasons as someone else mentioned).
