A reader wrote to us recently to inquire about some gross “things” she found in her yard. The things might more precisely be described as fat and white with brown heads, and the reader was wondering if she found some sort of worm or larvae. We are basically certain she found grubs, which are also called “lawn grubs” or “grub worms” (even though they are larvae), and below we provide a little more information about these creatures. The reader also mentioned that she is concerned about the “dangers they may pose for humans and pets,” so we’ll address this matter as well.

Not long ago, a reader wrote to us about a problem he is having with worms and his lawn. More specifically, he thinks that the worms in his lawn are causing it be uneven and rough, and as a result he is wondering what kind of worms he is dealing with and how he can get rid of them. One’s lawn is a precious thing, so we understand his dilemma.
