They are about 1 1/2 inches long and they do fly and bite. They raise their tail section as a defense.
The Devils Coach Horse Beetle only has a very short range in the US and they are known to be a mainly beneficial insect so you will not be able to find an insecticide that is labeled for them. Talstar PL Granules are labeled for the really hard to kill insects such as scorpions and centipedes so it may work for the Devils Coach Horse beetle.
