Unless they are spying on you you have little recourse... the government considers anything above your property that's navigable airspace as a public thoroughfare so they have the right to fly through it... they cant spy on your sunbathing daughter but if they catch a glimpse flying by there's nothing you can do. Its based on this case https://en.wikipedia.org/wiki/United_States_v._Causby
I would also suggest against taking matters into your own hands to shoot down the drone or some jamming device as messing with aircraft in flight is a big no no even if its just a little drone. its a safety thing
Under the Texas Privacy Act of 2013 [1], a drone operator capturing an image of a person on private property is subject to a $5000 civil penalty. Distributing the image can result in significantly higher damages. If done to surveil it becomes a crime in addition to a civil penalty.
