Panic veld grass has a well-documented presence across various continents. Originally hailing from major regions in Africa, panic veld grass has since been introduced to parts of Europe, Asia, and the Americas. In new territories, panic veld grass is sometimes thought to be naturalized, and it may have an impact on native ecosystems, particularly in certain areas where it is considered invasive. Notably, in Oceania, panic veld grass has established itself to the extent that it may disrupt local flora. However, the plant's exact influence on ecosystems outside its native range warrants careful observation and study.

Panic veld grass is an aggressive weed grass that grows in California and Hawaii in the United States, as well as China, Australia, Italy, and New Zealand. Its habitats include forests, grasslands, and woodlands. It is on the state invasive species list in California, considered an environmental weed in Australia, and is invasive in Hawaii, Australia, and New Zealand. Its ability to seed throughout the year and quickly build large populations all contribute to its invasiveness. It can outcompete and restrict the growth of native plants, eventually eliminating smaller species. Control the weed's spread by hoeing, pulling the weeds out by hand or use of an herbicide.

The best season for the removal of panic veld grass is spring, ideally before the weed reaches its reproductive stage to prevent the spreading of seeds. Here are some organic or interesting methods for controlling or removing this plant:
