A bug(living creature kind) got in my backbone

My left trigger and joy stick started acting funny, like they were constantly being pressed. Decided to pop it open to see if there was any obvious problem. Nothing seems broken, but there was an actual insect inside.

If you open up the sides and put the controller face up, there is a little square ish piece of tape(?) inside the back half near the top. I'm assuming it's a little bit of padding to reduce noise from releasing the trigger. The insect was underneath that. It's big enough you can see it's bent and squished from the trigger hitting it. I'm guessing this kept the trigger slightly pressed. I got the insect out, but my left trigger won't work now. Any suggestions?
