Chafer Grub Damage and Solutions

The European Chafer Beetle is an invasive insect species first discovered in New Westminster in 2001. Since its initial discovery, it has spread throughout Metro Vancouver cities causing significant damage to lawns, fields, parks and other areas.    

While it has only a one-year life cycle, it reproduces rapidly and causes widespread damage by feeding on the roots of grass and turf. Further damage is caused by birds and animals digging for the chubs, which can tear up grass and turf. The infestation can result in brown patches and a chewed up lawn. 

How do you know if you have a chafer beetle grub infestation?

The best way to determine whether your area has been affected by chafer beetle grubs is to cut a 30 cm x 30 cm square patch of the area. Turn it over and look for white, stout c-shaped bodies with light brown heads. If you find them, consider taking action.

How to resolve a chafer beetle grub infestation?

Infestations are far less likely to occur in healthy grass. By doing proper maintenance including regular fertilization and liming, aeration and overseeding, it will keep grass healthier.   

Microclover and Tall Fescue are hardier, beetle resistant grass species that are well-suited for areas where there is an incidence of the chafer grub. 

Premier Pacific Seeds produces two beetle-resistant grass seed options:
