Mosquito sound repellents are useless for insects, but solved my bat problem.

A bat loved to defecate in my son's bathroom. The most internal room of the house. I've put a sound repellent in the bathroom and it stopped happening

That's funny because bats would eat the mosquitos so by driving away bats you're actually making the mosquito problem worse.

Just probably don't want to put those outside, that would probably count as noise pollution for them.

Interesting. What's the brand that worked for you?

A cheap one from AliExpress.
