between brick pavers stubborn weed.

What is this crap between pavers. Used Season Long by Ortho I beleive. Is there a better treatment? I have to treat 2-3 times a year. They wont let me anymore because of pets and kids playing on it all the time.

Easy fix would be pressure wash it get all the crap put and poly sand it works everytime. One bag should do 20-30ish sqft.

Not sure. Could be Veronica--tough weed. Prefers cool weather; winter annual under some conditions. Drive sometimes works --see label. But not sure if OK in New York.

Quicksilver might work--and toxicity is very low.

How about a torch? If someone objects to herbicides or I have concerns about off target effects, weeds are burnt. Putting poly sand in between the bricks after the weeds are burnt off is probably a good idea.
