How to report a suspected pesticide-related bee kill
The Oregon Department of Agriculture (ODA) Pesticide Program, responds to all allegations of bee kills or die-offs alleged to be pesticide related.
Pesticide investigators may
- Collect physical evidence (such as dead bees or treated vegetation)
- Collect and review pesticide application records
- Interview beekeepers and pesticide applicators
ODA often works with Oregon State University (OSU) and beekeepers to identify whether bee kills or die-offs are pesticide related, or the result of poor nutrition, parasites, disease, or other factors. In certain instances, dead bees collected by ODA investigators are analyzed by the ODA laboratory for pesticide residues.
During the investigation, ODA uses standard investigative protocol as well as US EPA Guidance on responding to bee-related incidents. The investigative findings are provided to the US EPA on a quarterly basis.
When to contact ODA
Alleged pesticide-related incidents must be reported in a timely manner. This is because pesticide residues break down over time, bee carcasses degrade, crops are harvested, memories fade, or pesticide application information may not be available.

You also can call 211 to report a bee-related incident 24 hours a day. Information provided will be directed to the Pesticide Program for follow up.

Pesticide advisory about pollinators
Pollinators and pesticide labels
Pollinators are extremely important to Oregon's agricultural community, pollinating many crops. Oregon is proactive in protecting bees and other pollinators and currently requires specific label language prohibiting the use of the neonicotinoid pesticides, dinotefuran and imidacloprid, on linden, basswood and Tilia species trees.
At the federal level, the Environmental Protection Agency (EPA) has required special label restrictions to neonicotinoid pesticides in order to protect pollinators. The active ingredients that will have special label language are as follows:
