South African Bark beetle

From Johannesburg South Africa: Where can I get predators of Checker Beetle to eat Bark Beetle or what can I spray for Bark Beetle?

The use of checkered beetles (Cleridae) for bark beetle control may not be particularly effective, and I will have to do some digging to see if there is any commercial source for them as control agents (I’m doubtful at this point). Also, control measures will depend to some degree on the particular species of bark beetle involved. For some, the only recommendation is the cutting down and destruction of infested trees.
