South Texas is home to many wasps species.  The most common are the paper wasp, red wasp, yellow jacket, and the mud dauber. Yellow paper wasps and red wasps are not aggressive by nature unless their nest is being approached and then they will defend their home. Stings can be very painful. Yellow jackets are very aggressive and will sometimes attach even unprovoked. Yellow jackets can nest in homes in the ground and are very protective of their home. The least dangerous is the mud dauber which will rarely sting even when provoked.
