What I found is that there are a number of simple, small, ultra-low power devices that plug into an electric outlet and consume a minuscule amount of power while solving the problem handily. the units that I purchased are made by Kooder, and I got them from Amazon for about $12 each.

When plugged in, 2 small ultraviolet LEDs come on to attract bugs to the electrode grid inside where they die a quick and quiet death. No loud zapping! This subtle purple light can also serve as a modest nightlight.

I also tested it by inserting a screwdriver (holding the insulated handle carefully) to short out the electric grid and it did produce some substantial sparks. For this reason it would be wise to keep this away from young children.
To give the device a rigorous test, I plugged it into an outside outlet for a couple of nights and it caught quite a number of bugs.

As someone who designs electronic products for living, I would be very proud of this design.
There are quite a variety of similar devices on the market, including a very clever version that screws into a lamp socket and incorporates an LED light.

I don't think these devices should be confused with heavy-duty bug zappers. They are really designed for the occasional incursion so should not be used in the same way as a larger zapper. I would definitely not recommend them for outdoor spaces other than small screened in porches.
