We have only a small amount of lawn approx 150m², it is infested with lawn
beetle. Over the past 6 months I have used a very effective chemical from
Bayer which brings the beetles to the surface, if they are not eaten by
birds they die. I lost count after 200, I have now done this twice and there
is still evidence of their presence.
People have told me they are seasonal and just to live with the problem. Any
information on this subject would be greatly appreciated.

Thanks in anticipation
Adrian
