Provent a mite contains .05 % Permethrin...

There is a spray you may find in stores that carry camping supplies, Repel Permanone, that is for spraying camping gear against ticks, it has the exact same concentration of permethrin...

In pharmacies, you might see little aresol cans for human lice, with the same chemical, to spray sheets, beds etc...

Hope this helps, most important is make sure permethrin is the only active ingredient, and allow the spray to dry completely...it's toxic to reptiles when it is wet...don't let them near the wet spray...
