I found that there are two tags for pests. Both pest and pests. I think it would be best if we could make pest a synonym of pests.
Thanks for pointing that out. I've merged the tags (since they mean exactly the same thing), which automatically creates a synonym so any future attempts to use pest will get the pests instead.
