Yes, they work well on young annual weeds, but perennials like bindweed and dandelions come right back up. Same problem with vinegar, soap, vegetable oil, or most other "natural" weed controls.

Brother in law bought one, scorched earth in a matter of days. he was pleased as punch till they regrew from the roots again. waste of money. either dig out thoroughly or use a systemic weedkiller [glyphosate] to kill the roots.

Hya Thanks again for your advice, i was'nt sure about using one of these items on My weeds, but its always best to ask advice, and i have decided against Buying one of these Gas Weed Treatment, it will save me the time and trouble to find out that its no good, and will also stop Me from throwing money away, so thank you again, piperdanny123

Previous question
No good in that they don't have any effect on the weed roots below so they pop up again quickly. I find a weed killing spray very effective in that it kills the whole plant from top to bottom. I have seen them at the local garden center and the sale of these things hasn't exactly been catching fire.
