We have the tags pest and pest-control, neither of which have tag wiki guidance.
At the time of writing, of the 47 pest and 137 pest-control questions, 30 have both tags. 16 of those have no other tag.
Should these tags be synonyms? If not, shouldn't we provide guidance on their differences?
Incidentally, there is extermination, a synonym mapping to pest-control. Also, more specific tags such as ants and mice. I'm not suggesting any change to these.
