Juvenile plants with small root systems can be pulled by hand when the soil is moist. However, manual removal of larger plants must include destruction of all roots and runners because portions of the root system left in the soil can sprout.

Applications of herbicides for containing glyphosate or triclopyr over successive years may give satisfactory control. Glyphosate will kill grass so use only on beds of winter creeper where there is no grass. Triclopyr will not injure grass.

Attached are several PDF files with more info and options for eliminating winter creeper.
