Okay then go with the electric ones. I had the propane trap and while it worked well the constant propane tank refill was a drag and I certainly couldn't afford multiple.
Enter Dynatrap + Mods.
Dynatrap uses an electric light and fan. It works medium but if you put the octenol attractant in the catch basket it really turbocharged it. Want to kill more? Hang a "bug ball" under the trap covered with Tanglefoot spray. Any mosquito that lands on the ball dies there because they are stuck. The ball will be thoroughly disgusting looking quickly but very effective.
I've spent many years combating.
The Bt mosquito dunks help for any standing water ( have gutters?)
