Well according to that site, you're supposed to call if you find one, and then they are supposed to come out and look at your yard. If you decline, they will ask your neighbors to look at their yards. Then, they can try to get a court summon to look at your yard. Apparently those things are pests, and no one wants them in their counties, so maybe it's best if you don't tell anyone about those sharpshooters, if you don't want your garden being discovered.
