actually some beetles would kill it...got a bucket full of them to send?
Bad idea..........especially since once the trees die, the beetles will go in search of other chow.
And if the authorities find out it was your property where it started on, they're gonna ask questions that could lead to serious fines.
Best to drill a core to the center of the tree, fill it full of bleach (the reason you want to drill a core to the center is 2 fold.....one to get to the center part of the tree called the heart, which will carry the bleach throughout the tree, and the other part is so that you can re-insert the core to cover the evidence you've been tampering with it.
You're welcome.
