Tell this giant hardware chain: Stop selling Roundup
Glyphosate — the main ingredient in the popular pesticide Roundup — is devastating monarch butterflies.1

Roundup is wiping out the milkweed that monarch butterfly caterpillars need.
Roundup is ubiquitous. Every year, millions and millions of pounds of it are sprayed across the country.2
And all of that Roundup is wiping out the milkweed that monarch butterfly caterpillars rely on for food.
Monarch butterflies need our help. That’s why we’re calling on Home Depot to stop selling Roundup.
Monarch butterfly populations have plummeted.
In the past few decades, monarch butterfly populations have plummeted by as much as 95%.3
One big reason? The pervasive use of Roundup.4
Monarch caterpillars need one thing to continue their life cycle and develop into the butterflies they’re meant to be — and that’s the milkweed plant. It’s the only plant that monarch mothers will lay their eggs on, and it’s the only plant that monarch caterpillars will eat in the early stages of life when they need energy to grow and develop.5
But the increased use of pesticides have contributed to a major decline in milkweed. In turn, this decline has left monarchs with fewer and fewer places to lay eggs and their caterpillars with less and less food.6
Take action to protect monarchs from glyphosate.
Roundup isn’t just dangerous to butterflies. The World Health Organization has labeled glyphosate a “probably carcinogenic to humans.” One study estimates that exposure can raise the risk of cancer by 41%.7
Killing weeds more easily isn’t worth the damage that glyphosate inflicts.
Bayer — the company that purchased Monsanto, the original maker of Roundup — has said they’ll reformulate the pesticide to remove glyphosate, but only from some of their products.8
Until that’s done — and the new version is proven safe — we’re calling on Home Depot to get Roundup off their shelves.
Home Depot can make a difference on this issue. As one of the largest home improvement stores, Home Depot can cut down on the millions of pounds of Roundup sprayed by taking the product off its shelves. Home Depot can also set a positive example for others in the industry to follow.
