Bugs in the CPAP

[Crimson Nape]

A heads-up about the Mint family plants; They are a very invasive plant and will try to takeover everywhere.

Was it inside your mask? If not (so that you could swat it) then it did not come out of your CPAP.

No, walking on my arm. When I found the centipede it was hiding in the bed frame. Hence, the concern. It could have been hiding anywhere. 

I plan to buy an end plate (thanks for the suggestion), and leave the mask attached. I have a cat and a dog, hence, the removal during the day. I have spares if they tear them up.

The end plate still leaves an outlet opening to attach a hose. Why not just slip the machine in a zip-lock bag?

In truth this is just something I never worried about, and probably won't. I think you have already exterminated your problem.
