WHAT IS BEING DONE
Starting in 1998, the U.S. imposed strict controls on all wood packing material from China. Meanwhile, scientists are racing to find ways to fight the bugs that are already here

1. Insecticides
The insecticide Imidacloprid injected into trees has shown some success at preventing infestation but is not effective against tunneled larva

2. Biological Controls
Researchers are trying to develop living agents, such as fungi or parasites, to attack the beetles without harming native species

The only way to find out whether a tree is infested is to climb it and look for signs of the beetles. When holes like these appear, it's too late
