I think you're looking at a very hard sell. It's a secondary term for "bug zapper", which itself would be a hard sell. I suspect the only interested buyers would be small companies who specialize mainly in manufacturing and selling this product.
Does a company like that exist? Possibly... although it looks like these things are more or less mass produced by large companies and then sold via Amazon or at major hardware/department stores. Owning an exact match name for a product like that doesn't typically interest the potential buyers.
The fact that it's a secondary term for the real name of the product makes it worse. And actually... I would even prefer the plural over the singular so it could at least be appealing to someone who wanted to buy it for an affiliate site that sells bug zappers.
It looks like registration fee value to me. I would not renew, but try listing it for a few hundred bucks on the major marketplaces and see what happens.
Additionally, you could try doing outbound to make a sale, but I'm not sure the time investment would be worthwhile.
