A Serious Threat to Endangered Species
Malathion is one of the most toxic insecticides still widely used in the United States. It poses a direct risk to more than 1,500 endangered species. Originally developed for military purposes, this neurotoxic chemical is now sprayed in environmentally sensitive areas, placing butterflies, beetles, dragonflies, and other vital pollinators in danger. Many of these species are already struggling, and Malathion is accelerating their decline.
Despite extensive scientific evidence, the U.S. Fish and Wildlife Service recently concluded that Malathion does not present a significant extinction risk to protected species. This finding sharply contradicts the agency’s 2017 assessment, which warned that the chemical threatened the survival of more than 1,200 species.
A Controversial Reversal
In 2022, following pressure from the pesticide industry, the Fish and Wildlife Service reversed its earlier conclusions. This decision alarmed conservationists, who questioned whether industry interests were placed above environmental protection. As a result, thousands of plant and animal species, including critical pollinators such as the Karner blue butterfly, remain exposed to ongoing chemical use.
How Malathion Causes Harm
Malathion affects insects by disrupting their nervous systems. While intended to control pests, it also harms non-target species, including pollinators essential to ecosystem balance. Even limited exposure can severely reduce populations, especially those already affected by habitat loss and climate-related changes.
The U.S. Environmental Protection Agency has acknowledged that Malathion impacts approximately 97 percent of species protected under the Endangered Species Act, including birds, mammals, fish, and pollinating insects such as bees and butterflies.
Why This Matters to Everyone
Pollinators play a crucial role in agriculture and natural ecosystems. Without them, plant reproduction declines, food systems weaken, and ecological stability is threatened. Yet millions of pounds of Malathion continue to be applied each year across the United States.
Human health concerns also exist. The World Health Organization has classified Malathion as “probably carcinogenic to humans.” Long-term exposure has been associated with respiratory problems, fatigue, and other health effects.
Take Action Now
The continued use of Malathion places wildlife, ecosystems, and communities at risk. Without swift action, the damage may become irreversible. Protecting endangered species means protecting the systems that support life itself.
Signing this petition is a step toward accountability and responsible environmental policy. By calling for an immediate ban on Malathion, we can help safeguard pollinators, preserve biodiversity, and promote a healthier future for both nature and people.
