If you've seen what appears to be large wasps flying around this summer, you have nothing to worry about.

The giant wasps are called Sphecius speciosus, or Cicada Killers.

The Texas A&M Agri Life Extension says they've gotten a lot of calls about the flying bugs.

Cicadas make the loud buzzing noise at night, and Cicada killers control the noisy bug population.

So our bug expert suggests letting them do their job.

"They'll take them down into the ground and they'll stuff them into this burrow that they have in the ground and they'll lay an egg on it, and when that egg hatches then the Cicada Killer larvae will actually eat the Cicada that's provided. So it's a way of pest control, but you don't really have to do anything," said Wizzie Brown with the Texas A& M AgriLife Extension.

Female Cicada Killers are capable of stinging, but usually don't. Males are often territorial and may act aggressively, but they don’t possess stingers and are completely harmless. 

Cicadas are most prominent during the summer.

According to school's website, Cicada Killer wasps are easy to spot due to their large size; they are typically 1-1/2 to two inches in length. The female cicada killer digs homes for her young in home lawns or in any sandy, bare, well-drained soil exposed to full sun.

Although their name suggests otherwise, Cicada Killers help keep neighborhoods a little quieter during the summer.
