I'm not sure why so many people have issues with this machine, but I'm glad I didn't listen. We have tried all types of fly/mosquito catchers:

The cheapest and easiest way to catch them, inside or outside is with the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/TAT-Fly-Paper-8Pk-Fly-Paper-Ribbon/dp/B001MA4C8S/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">TAT Fly Paper, 8Pk Fly Paper Ribbon</a>.

Another that works very well OUTSIDE is the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Rescue-FTA-SF4-Reuseable-Fly-Trap-with-Attractant/dp/B00004TBKG/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Rescue FTA-SF4 Reuseable Fly Trap with Attractant</a>, but they STINK horribly (and the smell really travels!). Probably better used on a large property away from people.

The&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Stinger-UV40-40-Watt-1-Acre-Advanced-Bug-Zapper/dp/B0007RXD9Q/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Stinger UV40 40 Watt 1-Acre Advanced Bug Zapper</a>&nbsp;is just about the WORST, not worth any amount of money, in my opinion.

But this&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Stinger-MA06-Insect-Mosquito-Indoor-Trap/dp/B0007RXD8M/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Stinger MA06 Insect Mosquito Indoor Trap</a>&nbsp;does the trick very well. We put it in a corner in our kitchen and turn it on at night. It attracts flies, mosquitoes, and other insects with the light, and the fan pulls them into the chamber below where the fan dries them out and kills them. I have NEVER, not even once, had anything fly out when turning the machine on, or emptying/cleaning the chamber. We run water over it before opening it for cleaning, maybe that's the difference.  Anyway, this is the only electronic trap that works for us and we would purchase it again.

Noise: It's a fan, fans make noise. Most babies don't need quiet to sleep, I used to use nap time for vacuuming (they get used to noise, they sleep better as adults)!  That said, I wouldn't necessarily want to use these IN a bedroom as they ATTRACT pests.  Try putting it in the hall outside the bedrooms or the kitchen or bathroom.
