I used to work with the GFC in FLA years ago. One of the things we were doing back then was killing non native plants. These plants were and are a huge problem in South Florida. We would put plant killer in sprayers that were mostly diesel, cut the plant or tree around its base and then spray with the poison.
This was done at the direction of state biologist in the Everglades and in protected areas.
The Melaleuca trees could only be killed by poison. If you burned them they would spit seeds. If you cut them down the stump would sprout and if the trunk was left on the ground it too would sprout. This weed tree was introduced to suck up the ground water and drain the swamps. I have seen newsreels from the 20/30's showing box loads of the Melaleuca seeds being tossed out of airplanes.
I have not used an indoor bug killer in years but I do remember when the carrier was diesel. Lordy but that stuff stunk up the house.
Later,
