I found this on the web site noted on the tag.
We have been actively engaged with the EPA on the topic of colony collapse disorder since 2012 and have helped the industry change the way it thinks about growing residential plants. In 2016, we launched Nature’s Nutrients, flowering plants grown without the use of neonicotinoids that attract pollinators and provide foraging opportunities.

That same year, we set a goal to have live goods that are neonicotinoid-free by 2019. Our local growers have risen to the challenge, and we are now approximately 98% neonicotinoid free across our supply chain. Although the science is still unclear around neonicotinoid exposure from residential plants to the honeybee Colony Collapse Disorder, we continue the pursuit of this goal. The challenge to achieve 100% has been in nuances like new supplier onboarding, pest infestation, citrus regulations, and 3-year plus growing cycles.
