Roundup, the most popular and profitable weed killer ever sold, uses glyphosate as its most active ingredient. Glyphosate is toxic to most broadleaf plants and grasses. It kills most plants it comes into contact with, instead of targeting certain weeds or plants.
Monsanto, no longer an active company, developed the product. Because glyphosate kills anything it touches, Monsanto developed plant seeds that were genetically modified to resist the damage of Roundup. This is when residential Roundup sales skyrocketed.
However, as the years went on, science questioned the safety of glyphosate. Studies have shown that the chemical might cause illness to humans and cause damage to the environment. The International Agency for Research on Cancer categorizes glyphosate as possibly carcinogenic to humans, as in this toxin may cause cancer.
In 2018, Roundup was purchased by Bayer. By then, consumers had filed thousands of lawsuits linking Roundup to cancer. Bayer committed to begin in 2023 replacing “its glyphosate-based products in the U.S. residential Lawn & Garden market with new formulations that rely on alternative active ingredients.”

Pesticides significantly endanger biodiversity by poisoning non-target organisms, reducing food sources for wildlife, and harming soil health. Avoiding synthetic pesticides—especially insecticides and herbicides—supports pollinators, birds, and soil microorganisms essential for ecosystem resilience. Opting for organic, integrated pest management methods fosters a healthy, self-sustaining environment.

Pesticides to Avoid

Mosquitoes are often controlled with broad pesticide spraying, called fogging. These treatments don’t just affect mosquitoes—they can impact other insects, wildlife, and people, and they don’t address where mosquitoes reproduce.
The Mosquito Bucket Challenge offers a more targeted approach. By controlling mosquitoes at the source, it reduces populations without affecting the rest of the ecosystem. It’s safe, it's affordable, and it's better for biodiversity.
