Gardeners Beware: Bee-Toxic Pesticides Found in “Bee-Friendly” Plants Sold at Garden Centers Nationwide

Bumblebee colonies foraging for six days on 

clover in turf treated with a clothianidin grub-control 

product at label rates not only experienced bee kills, 

but the surviving bees produced no queens.

However, as this report shows, gardeners may be 

unwittingly purchasing toxic seedlings and plants 

attractive to pollinators for bee-friendly gardens, only to 

poison them in the process.

Neonicotinoid pesticides can poison bees directly, but even 
low-level exposure can lead to sublethal effects such as a 
compromised immune system, altered learning, and impaired 
foraging, effectively exacer-bating the lethality of infections and infestations.

Neonicotinoid residues were detected in seven out of thir-
teen samples (54 percent) of commercial nursery plants.

The widespread agricultural use of neonicotinoids is a 
common exposure pathway for bees; however, cosmetic 
use of these pesticides in gardens, lawns, and 
landscapes may be an important factor in declining 
bee and wild pollinator health.

Because the neonicotinoid pesticides are systemic and 
persistent, exposures to low levels of neonicotinoids 
in pollen and nectar over an extended period of 
time (weeks to months) is a serious consideration.
