So it seems that Soil lobbyist group Soil Association have got their way. Bug killers such as Provado Ultimate Bug Killer, as well as several others, have been removed from big stores. This is due to the ingredient 'Neonicotinoid' being linked to the decline in the bee population over the years.
Apparently when you spray a plant with the bug killer, it contaminates the pollen and nectar which can disorientate the bee's and cause them to lose track of where their hives are located, hence the population decline of bees. Bit of a shame because Provado always seemed to work well for myself and many other carnivorous plant enthusiasts. Just a shame there isnt a significant reduction in the wasp population!
