University of California’s Integrated Pest Management Program has put together a searchable database that lists numerous pesticides and their known level of risks for bees. Simply search for pesticides by their common name, add them to the list, and view their ratings of toxicity for bees.
Ratings range from I to III, with I being the highest concern for bees and III being no level of concern for bees.
Important Note: The trade names used in this table are those used for agriculture, not for environmental horticulture products. Therefore, environmental horticulture growers should stick to using the common names option when searching for ratings.
