Be careful when you wash those eggs. The water should be 10 degrees warmer than the egg itself. If you use cooler water or water of equal temperature, the pores of the egg will suck in the sevin dust and anything else on the surface. Do not let the eggs soak. When you are finished washing the eggs, coat each one lightly with mineral oil to prevent spoilage.
Wazine only treats roundworms, so it will have no effect on the mites. For mites, you'll want either ivermectin or Eprinex, or if you can, apply permethrin or sevin dust topically. Any of these treatments will need to be repeated. Repeat ivermectin or Eprinex in 10 days. I would repeat the dusting at 5 days and 10 days, though I have no evidence to back up that assertion. Best of luck.
