Proof it really works

Chafer grubs had caused problems for years at Stonehenge by eating the grass roots. This was exacerbated by jackdaws pulling up the grass to seek out the grubs, resulting in unsightly bald patches. Add to that the constant flow of visitors and English Heritage had to keep moving visitor paths away from the damage that encircled the famous stones. There was yet another problem too, when the chafer grubs hatched, the resulting swarm of beetles would fly up at the visitors who found it extremely off putting to say the least. Due to the large number of visitors including children and with local wildlife and sheep grazing in the neighbouring fields, there was no way that English Heritage wanted to resort to chemicals so they had to come up with a natural environmentally friendly solution Nemasys Chafer Grub Killer. Within a week of the first application, back in September 2006, the secondary damage from wildlife reduced considerably. A review of the result in April 2007 has led English Heritage to order more Nemasys Chafer Grub Killer enough to treat an area twice the size of the original application.
