Lawn Beetles

Answered by Gavin Posted in Category Pest Control & Nature

Dear Harrod

I currently have hundreds of beetles emerging from my lawn. Can you advise on which product I should be using for this? If it helps I have attached a photo of the beetles.



Dear Roy

Just in case you didn't already know, the beetles emerging in their hundreds from your lawn are Garden Chafers (Phyllopertha horticola). The larvae of these feed on the roots of grasses and various cereals, while adults feed on leaves of various shrubs and trees. You can treat the larvae with nematodes ) which is very effective if you follow the instructions. Alternatively / also you can trap the adults in a pheromone trap ) , however i think this second option maybe too late now as the majority of adults would have emerged, mated and laid eggs by now.


Thanksfor your query, hope this helps.

Best regards,

Believe it or not I began my career as a cobbler, however, after 11 years in the trade I decided to pursue my boyhood dream of studying insects (this I had already been doing for much of my life!). Whilst studying towards this career change I applied for a part-time post in the entomology department at one of the UK's leading plant biological science research institutes. I was fortunate enough to secure the post, to which I have now occupied for 12 years full-time.

Many thanks will treat as recommended. I have already captured as many as I could, hopefully reducing the problem. Regards Roy
