Beetles June beetles, carpet beetles, weevils

The June beetles thumping your screens in early summer are harmless adults — their grub children eating lawn roots are the problem. Indoors, tiny carpet beetles do the fabric damage people blame on moths, and pantry weevils arrive hidden in bags of rice and flour.

Questions, answered straight

Grubs or drought — how do I tell why the lawn is brown?

Grub-killed turf pulls up like loose carpet because the roots are gone; drought turf stays anchored. Grubs are covered by the Lawn Bug Plan, and we’ll show you the count before treating.
