Stinking chamomile, naturally thrives in regions of Europe, Northern Africa, and parts of the Middle East and Southwest Asia. The plant has since been introduced to ecosystems across various continents including South America, North America, Asia, and Oceania, demonstrating its ability to adapt to diverse climates beyond its native range.

Stinking chamomile poses a moderate toxicity risk to cats and dogs. Ingesting any part of the plant can cause poisoning, leading to symptoms like vomiting, diarrhea, and lethargy. Immediate veterinary care is essential if poisoning is suspected to ensure the animal's health and safety. Cat and dog owners should prevent their pets from consuming stinking chamomile and monitor their access to it.

Stinking chamomile is originally from Europe and parts of Asian regions. Being a weed, it possesses certain characteristics that deem it harmful, especially in a gardening context. First, it has an incredible reproduction capacity as it produces a high volume of seeds that can survive in soil for several years and germinate under favorable circumstances. Second, it has an aggressive growth habit that enables it to invade and sometimes even outcompete other native and cultivated plants for essential resources like nutrients, water, and sunlight. This infestation can result in a significant reduction in plant diversity and crop yields. Besides, it emits a foul odor that can be unpleasant for many gardeners. The prime method of stinking chamomile's spread is through its prolific seeds, which can be dispersed by wind, water, wildlife, and even through human activities such as farming and gardening.

The best season for removing stinking chamomile is in late spring or early summer, just before the plant starts to flower. The weed should ideally be removed in the vegetative state, before flowering, to prevent seed production and spreading.
