I killed the Black Widow spiders crawling out of the wheel wells too. One was a gorgeous big fat Black body with red design on it's back.
Lucky you. You may have a rare black widow, one with marking on the back. They seem to be less common. The ones we have, have a big red dot on the belly. The female, that is. The only one to worry about. The males have marking on top, but are harmless.
"Adult female northern widow spiders are shiny black or brown-black with 2 reddish triangles on the underside, resembling a split hourglass.
Markings of the same color but in varying patterns are sometimes present on the back.
Adult males are harmless, and usually have yellow and red bands and spots over the back."
Don't you love these charming creatures ?
One of the first things we done for our trailer, was keep away nature from it
as much as possible. Nature has the lousy habit of trying to get in: here is something that I rather not see too often - in - or out. (it's about the size of a mouse)
We built a concrete pad surrended by rocks. Rocks seem to be the only place we can grow grass on .... ....and things crawl in the grass.......... Nature wins in the end.
