If getting rid of the bugs around the house isn't improving the quality of life around that house then I'm on the wrong quest...

   This is what the interior of the zapper looks like after I blow the dead bugs out and its ready to spend another night zapping.

   And this is what it looks like after one night. By morning there is not one place the bugs can find to die by electricity.

 

I can still see a few millers trying their best to get in there to die but can't find any empty spots to become martyrs. 

Wow! That's a lot of bugs!!!

Oh my word! That’s a heck of a zapper. 

I don't think they sell the larger sizes we use to use at the go-cart track any more. They were bought in 1984 and were still going strong in 2010 or so. You could stick a blade of grass in one of those and they would just about knock you down. These might do the same but I have gotten smarter since then!!!

You can still get the big one's on Amazon.

I've got one like your little one  now, works pretty good.

They will work better if you will blow them clean each day.
