It is true to say that there are many other claims to 'The Last Word In The English Dictionary' such as ZZZ the so-called noise we make when asleep or indeed zyzzyva a noun - relating to any of the various tropical American weevils, but being a UK based business directory, we could't find any Britsh zyzzyva pest controllers or zyzzyva eradicators.

Actually we couldn't find any suppliers of Zythepsary related products or services either but to be a proper A - Z, we need to at least attempt to provide some sort of reference to one of the last words in the English dictionary.
