As long as the spider was at the far, un-used end of the porch the spider was a novelty, something to go out and look at in the evening to see what was going on. to stare out while talking on the phone. But one day the spider worked his way down and made a web in the middle of the porch, way to close to the table we sit at and read.
This was no good so it was time for the spider to go.
Imagine the fireball created by a lighter and an aerosol can.
This fireball was probably at least twice that big.
The spider was simply gone, I couldn't even find random burnt traces.
