Explaining the change Bayer Garden Product Manager, Alison Mulvaney, said: “Deltamethrin is a very effective weapon against unwanted garden insects.  It’s fast acting and can be used on ornamentals and a far wider range of fruit and vegetables than was the case with our previous active ingredient.

“We’re introducing this active ingredient in 2016 as a proactive step in recognition of the likelihood that the regulations and legislation around neonicotinoids will alter. 

“Retailers can sell existing stocks with no restriction; we’ve acted proactively to make the transition for both retailers and gardeners easy and seamless.

“Bayer Garden has a long track record of developing highly effective insecticides and actively supporting their responsible use.  This remains the case; we will continue to innovate, developing new and effective active ingredients to the pests and diseases gardeners face.”
