As Doolittle said I too have never tried strips so I don't know how affective they are. But I've become pretty good at eradicating mites. I have two tanks a 20 gallon and a 40 gallon so this process is a lot harder than with a tub. I throw all the bedding in my compost pile, then I take the tank (tub in your case) outside and spray it down really really good on Jet lol so I blast the crap out of the tank. Then I wash the enclosure with a lot of bleach and hot water and fill it up to the brim and just leave it outside full of water for an hour (idk if the mites drown but it can't hurt to try lol.) then I dump all that water out outside blast the crap out of it again with the Jet stream on the hose, wipe the tank down and let it dry/air out from the bleach smell. Then I bring the enclosure inside and treat with provent a mite spray, and then treat the infected snake with Reptile Relief spray. I let the snake sit with spray on him for 5-10 minutes then clean him up. After I've spent an entire doing all that treatment I never see another mite. Lol it's a lot of work with my 40 gallon tank because I'm a small girl and it's pretty heavy but after all the hard work the mites are all gone. Should be a lot easier with tubs though!you can give this a try if you want. It never hurts to try.
