We treated an Aboriginal scarred tree here recently. The tree was hollowed out and had also been stored outdoors for a prolonged period. The tree was about 4 yards long and 2-3 yards in diameter. The tree was sprayed inside and out with a product called Perigen (it contains permethrin - a low-toxic synthetic pyrethroid) using a pressure sprayer. It was allowed to dry for an hour before another application was carried out. We also repeated the process a week later. The treatment revealed that the tree had been home to all manner of bugs, including silverfish, cockroaches and red-back spiders (these are similar to your black widow spiders, if you gave them a gun). The subsequent application didn't reveal any further insect activity. I can send photos of the treatment if you like?
