Pesticide Samples

The pesticide samples are collected from wax combs or bee bread and are a composite sample from a single apiary. Prior to 2018, bee bread (stored pollen) was used for pesticide samples. During 2017 to 2019, samples are taken from wax combs. The charts below indicate if their source was from either wax or bee bread. The “n” values per pie piece are the total number of pesticides found within the category. Since each sample often contain multiple pesticide detects, the total number of detects will be greater than the total number of samples.

A table and list of all pesticides found and tested for in either wax or bee bread can be found at the following links.
