Query: False alarms...and always in the middle of the night

Like the other reviewers, the explosive gas part of the detector has given us false alarms - and always in the middle of the night! With the first false alarm, we had the gas co. come out and she said she'd seen this many times before. She said the likely culprits are air fresheners, dryer sheets, pretty much anything. Hmm, maybe it's my dog's gas that's setting if off? While natural gas is odorless, utilities add a "smell" to it so that unlike carbon monixide, you can smell it if you have a leak. Last night was the last straw, I am trashing this and getting a CO detector only!
