According to the group B&Q says it will no longer stock pesticide containing the neonicotinoid insecticide imidacloprid, because of "concerns about the potential for harm".
Wickes says it is to replace a product containing the neonicotinoid insecticide thiamethoxam, later this year.
B&Q says it is removing Bayer lawn grub killer only.
Imidacloprid, thiamethoxam and clothianidin have been identified by the European Food Safety Authority (EFSA) as posing a risk to bees.
Members of the Government’s Advisory Committee on Pesticides met on 29 January to discuss recent developments on bees and pesticides, including the EFSA report.
Bayer returned to Parliament yesterday (30 January) to discuss neonicotinoids with the Environmental Audit Committee.
