Alex Gomez, 30, was in his room relaxing when his downtime was interrupted by a notification on his phone.
But when he checked the footage on the app, he found that a wasp was the culprit and had rang the doorbell.
A video of the incident shows the wasp landing directly on the lens of the camera and setting it off.
Alex, a firefighter from Dallas, Texas, USA, said: “I was in my room relaxing when the doorbell rang.
“I opened up the app to see who it was and saw a replay of the wasp flying away.
“No other bugs have done it before.”
