The Walmart product is Equate Bedding Spray (for human lice) and is identical to Provent A Mite but costs $4 per can. I have used Equate for years with great results. Main thing is the Equate Bedding Spray does not have directions on the can for reptiles-never spray a reptile directly. Remove reptile/water bowl. Lightly spray substrate/cage furniture and let dry 30 minutes-very important. Replace reptile/water bowl and repeat in two weeks. Give it time to work.

When you buy Equate scratch your head vigorously at the check out-that will really freak out the clerk-major lol. Bill
