Tiny vetch, a herbaceous plant, is native to Europe, Asia, and North Africa. As an adaptable species, it has been introduced to regions in both hemispheres, notably in temperate and subtropical areas. This includes the introduction and establishment in parts of North and South America, an island in the North Atlantic, as well as select territories in the Southern Hemisphere spanning from Africa to the Pacific.

Tiny vetch is highly toxic to humans, especially through ingestion, causing symptoms like difficulty breathing and cardiac arrest due to cyanide. The whole plant is harmful, with seeds being particularly potent. Tiny vetch also mildly affects cats and dogs if ingested, causing symptoms like gastrointestinal upset and respiratory difficulties. Immediate veterinary attention is essential for pets showing symptoms.

Tiny vetch originates from Europe, North Africa, and southwestern Asia. It's considered a weed because of its prolific seed production and rapid growth habit. This small, wiry-haired annual plant produces several hundred seeds per plant that can remain viable in the soil for up to five years, contributing to its persistent nature. The seeds can easily become aggregated, making control more difficult. Tiny vetch directly competes with other plants for essential nutrients, sunlight, and water, stunting their growth and causing potential harm to gardens. This plant spreads mainly through seed dispersal, as well as by animal transportation, cultivation practices, or wind. Humans inadvertently aid in its distribution through their farming and gardening activities, and once established, it can completely dominate the vegetation of a site.

The optimal season for the removal of tiny vetch is during the late spring or early summer. This is the time when the plant has germinated but hasn't yet flowered or produced seeds, which can spread across the garden if not checked.
