I've been tempted before but I just use a glyphosate mix with a pressure sprayer. I buy a litre or more which dilutes something like 50:1 and works well, the weed dies from the root up and blocks the hole that the seeds got into in the first place.
No sympathy for the devil; keep that in mind. Buy the ticket, take the ride...
I have one, cool way to light a BBQ or burn maggots from a rotten mouse/mole corpse dragged home by the cat.
Can't remember ever using it weeds however!
Blow torch does the trick!
