​Off-White, waxy/plastic, round things found in shower. A little smaller than a dime.

We found this in our shower and on the shower walls of our new house. They weren’t there when we moved in and showed up after we started using the shower. My understanding is that the shower hadn’t been used regularly for some time.

We contacted a local pest company and they said that they don’t think it is pest related. They’re sending someone out to look in person.

Any thoughts?
