We had a bad box elder bug infestation in our Chinaberry or Golden Rain tree.
The picture is about actual size.
There were thousands. And they were very unsettling. When you walked out into the back yard they would run and try to hide. Don't like bugs that are aware of you and run.
Tried spraying bug killer, but was told the only way to get rid of them was to get rid of the tree.
Was driving down a road in the country and happened upon a large black tarantulas crossing the road. Stopped, grabbed a drink cup with a lid, caught it, took it home, then released it next to our garden shed that is right next to the chinaberry tree. The tarantula scampered under the shed.
Amazingly enough within a couple of weeks and for the next two years there were no more boxeldger bugs.
Towards the end of the 2nd boxelder free summer noticed a few bugs. They were coming back.. The tree and shed was on our property line and talking to that next door neighbor he commented that he had killed a huge tarantula in his back yard. Asked him if he had noticed there were't any boxelders around and he did. Told him he had killed my pet spider that was keeping them at bay.
Waited until there got to be a bunch of boxelder bugs again and pointed it out to the spider killing neighbor. Then went and bought a tarantula at a pet store and released it. Letting the neighbor know it about it. He noticed the boxelders disappeared soon after. Did not have a boxelder bug problem for next 5 years then we moved away.
