Starbar® Golden Malrin® Fly Bait Reclassified as a Restricted Use Pesticide
New EPA Classification Takes Effect on July 29, 2025
Schaumburg, IL, August 26, 2025 – Central Life Sciences, the makers of Starbar® products, announced that Golden Malrin® Fly Bait (EPA Reg. No. 2724-274) will be reclassified by the U.S. Environmental Protection Agency (EPA) as a Restricted Use Pesticide (RUP), effective as of July 29, 2025.
For more than 40 years, Golden Malrin® products have been controlling nuisance flies in agricultural, commercial, and residential settings. However, due to increasing incidents of product misuse, particularly involving the illegal poisoning of wildlife—the EPA has taken action to limit access to methomyl-based fly baits such as Golden Malrin® Fly Bait.
“Additionally, this regulatory change underscores the importance of using pesticides responsibly and in accordance with the label,” said Mark A. Taylor, Vice President of Innovation and Technology at Wellmark International, a subsidiary of Central Garden & Pet Company. “We also remain committed to supporting our partners and customers through this transition and ensuring Golden Malrin Fly Bait continues to be used safely and effectively by licensed professionals.”
Key Transition Details:
- 365-Day Sell-Through Period: A 365-day window begins following the RUP effective date, allowing distributors, dealers, and retailers to sell existing inventory that does not bear the new RUP labeling. After this period, all non-RUP labeled product must be removed from commerce.
- RUP Label Availability: Golden Malrin® products with RUP labeling is expected to begin shipping in early 2026. All inventory produced from that point forward will be the RUP label.
- Licensing Requirements:
o Furthermore, only licensed distributors, dealers and retailers may purchase and distribute RUP-labeled Golden Malrin® products.
o Also, the product may only be sold to end users who are certified to apply Restricted Use Pesticides, in accordance with state and federal laws.
Recommended Actions for Distributors, Dealers and Retailers:
- Review and manage current inventory to comply with the 365-day sell-through deadline.
- Obtain a state RUP license if intending to continue sales of Golden Malrin® products.
- Inform customers of the regulatory changes.
