Miteaway has formic acid as mite killing stuff.
You may use mere formic acid and make you own acid pillow.
Why covernement can not accept Miteaway? - Perhaps protect US products ?
The problem here in the US is the Dept of Ag doesn't register simply a chemical used for a Pesticide. They register the way it is applied. Although miteaway pads can be used, the strips and home made pillows are not. Strips will someday be here, homemade pillows never. Companies dont spend the money to register something unless they can make money on it. This is the reason Oxalic acid will never be legal. I dont like the pads or pillows because of the extra equipment needed, the cost of the pads and temp contraints. Our temp here can see 40's in the mornings and 90's by mid day. I like the Oxalic vapor because of the cost of a couple of pennies per colony but I dont like doing the 3 application a week apart. The quick strips although a couple of bucks a colony are just that "Quick" No spacers, no temp changing problems and one application for only seven days
