I recently considered the bugs-away ziwa pant, but the insecticide permethrin used in treating the pants bothered me, so I checked with the company that produces it, Insect Sheild. The rep told me that an EPA regulatory pesticide label was included with the tags on the pant, which says the bugs-away clothing should be washed separately. He said the EPA has allowed this treated clothing to be used by the military for some years but that Insect Shield had asked the EPA for permission to remove the pesticide label. The EPA agreed,so the pesticide warming was removed from clothing for the military,but not for civilians. The rep told me that stateside military personnel also wash bugs-away clothing with other clothing at home. Go figure. The difference for military personnel is probably based on need in combat scenarios, but how would it look if the label said, Okay for combat scenarios, but not in the states. I wonder if someone can shed light on this? Thanks! As I understand it the clothing should be washed separately because it sheds permethrin to other clothes.

I don't see anything on the label that says wash separately

The agitation of a washing machine deteriorates the Permethrin application as it knocks the molecules loose from the fabric. An application of Sawyer Permethrin (sold at Amazon) from a squeeze bottle lasts about 4 to 6 weeks. Sawyer recommends hand washing and air-drying. Dry cleaning removes the Permethrin from fabrics. "Permethrin is a synthetic pyrethroid pesticide used as an acaricide and insect repellent. It is employed not only in agriculture, but also in forestry, household settings, and public health programs. As a neurotoxin, permethrin affects neuron membranes by prolonging the activation of sodium, and is more effective against insects and aquatic life than mammals and birds. Due to this toxicological preference, permethrin especially poses risks to fish. For its effects on humans, permethrin has been classified as a type II or III toxin by the EPA, and studies of mice cells have demonstrated the chemical's potential to be carcinogenic."
