The pest control in question contains glyphosate, which is toxic to people and pets when contact is made while the active ingredient still is effective.

Concentrated Roundup painted directly on green portion of the plant should probably do it. 2,4,D will work also. 1 ounce to 1 gallon of water, spray till wet
