Vancouver Parks Board launches new weapon in fight against hungry beetle

VANCOUVER — The Vancouver parks board hopes a microscopic champion will win the fight against a pest chewing through the city’s grass boulevards, lawns and playing fields.

Starting this week, biologists will treat 31 sports fields with nematodes, microscopic roundworms that kill the grubs of the European chafer beetle.

The beetles were first discovered in lawns in New Westminster in 2001 and now infest grass through the region.

Eggs laid by the beetle develop into tiny grubs that grow as they feed on the roots of grasses.
