The following are sometimes used for weed control although it is not their primary use. They are not normally included in a discussion about biological control of weeds.

Vertebrates

Sheep and goats can be used to control ragwort (Senecio jacobaea) and blackberry (Rubus spp.).

Geese

Water birds such as geese can be used to control weeds in cotton.

Other higher plants

Higher plants may have an allelopathic effect on weeds and be considered live mulches.

Grazers

Grazers such as fish and ducks can be used for aquatic weeds. Snails and manatees have been assessed but found unsuitable.
