let’s look at an insect trapping plug that doesn’t try to zap them with electricity, but instead lures the insects to a replaceable sticky surface. This is a technique that has found favour in food processing areas due to the older high voltage zappers spraying bits of disembodied flies everywhere.

The construction of this is quite good, but it has the oddity of running the UVA LEDs in parallel instead of a simpler and lower current series approach.

The glass panel was completely unexpected and hints at a fairly professional design.

I’m not sure how effective this device is, as I don’t really have a fly issue to test it with. I’d actually expect strong point sources to be more attractive to flies as they would be a brighter visual attractant.

You could cobble a similar device up quite quickly using some LEDs and resistors connected to a USB cable, or some 5 or 12V LED strip and a stand to hold the sticky board.

A search on eBay for "insect glue traps" will find a selection of sticky boards.

This also keeps the channel independent of YouTube’s algorithm quirks, allowing it to be a bit more dangerous and naughty.
