Oh boy! The rhino beetles are active again...I found holes in the fresh potting soil of a couple of my adeniums. This is an indication that they have laid their larvae. The larvae eat the decaying matter of the soil, but will eat through roots if they are in the way.
I will spray insecticide into the holes they have made. On the other potted plants, I will place an extra layer of perlite on the surface...this seems to deter the rhinos.
Nasty buggers, these...they eat the heart of our coconut palms and will eventually kill the trees. They are very hard to control as they do not have natural enemies. They are not native here...were discovered here in 2007.
