The trap for adult garden chafer beetles, Phyllopertha horticola, aims to stop damage caused by the larvae feeding on grass roots.
"Significant secondary damage is also caused when birds and badgers dig up grass areas to feed on the larvae," said a representative for its maker, Oecos.
"The new garden chafer trap will provide an early warning system to the presence of this pest. Adult chafer beetles are attracted to the trap by a powerful pheromone."
Yellow vanes on top of the trap lure the beetles into the funnel trap, set up in May and June, when the beetles are emerging from the soil, the representative said.
Natural pest control consultant Julian Ives said: "This is useful for judging if chafer beetles are present and when to apply nematodes for controlling the larval stage."
