Sales of slug killer have doubled this year because of the wet weather. "Records suggest that a late onset year is generally followed by an early onset one," said Chalk.
"The consumer is more aware of what they are using in their garden and we have benefited as a direct result of this," he added. The company's Advanced Slug Killer is the market-leading "safe" slug and snail killer, he claimed.
GfK figures show that sales of Westland's Eraza grew 9.7 per cent year-on-year in January to May, 19.5 per cent up in May alone. Becker Underwood said it has sold out of its Nemaslug product.
B&Q reported a 44 per cent year-on-year increase in slug-pellet sales in June and a 74 per cent increase in July. It has sold 187 tonnes since May, up 51 per cent on the same period last year.
Meanwhile, Scotsdales recorded a 92 per cent rise in pesticide product sales in just one week in June. Bayer's Bio Slug and Snail Killer and Scotts Slug Clear Liquid have also sold well.
Garden Industry Manufacturers Association director Neil Gow suggested that garden centres could hold "biggest slug" competitions as an alternative to the traditional vegetable events.
