So I've been having a little problem with mosquitos in my house recently. I've been waking up with a new mosquito bite for the past few days

Mocha sleeps beside my bed, and I'm worried about them biting him, too. I need to find something to either trap or repel them away from my bedroom. I did a search online and found some ultrasonic mosquito repellents. They give off high frequency sound waves that repel the mosquitos. It says it can't be heard by humans ears, but I was wondering if anyone knows if they can be heard by dogs? I don't want Mocha to be irritated by the sound all night, if he can indeed hear it. Does anybody know anything about this?
