Khalid, this might actually be a senryu but I think you post it in the title as a haiku due to the word "varmint" a wild animal so I'm not sure anymore if it should be a senryu or a haiku but any who, yes. One has to be decent and polite but there are people who aren't and thus one can't remain polite, we can try to avoid them but who knows for how long.. :(
The syllable counts are perfect.
