Spider Control on Home Exterior?

[Dellfin]

I have white vinyl siding and the spider feces (?) is staining the vinyl especially in corners where webs are everywhere. There are little black stain spots that do not come off with any detergent I've tried.

I can't keep up with removing the webs/spiders. Are there any suggestions to reduce the spiders, such as a spray or some type of chemical that can be spread in the rocks to keep the spiders from crossing over from the lawn and crawling up the siding? I tried some wasp/hornet spray and it discolored the vinyl.

Also, any recommendations on a potent vinyl siding cleaning solution?

I would try Crud Cutter or Crud Cutter House Wash on the spots. Mix a solution of it up in a "Hudson Sprayer" and spray it on, let it sit a bit, then scrub it off. It will take a rag or sponge, mabe even a brillow pad, but it should come off. Or the Crud Cutter followed by a good hard powerwashing may work for you.

As far as keeping them off, there are some residual pesticides that you could put around your house, but they may be hard on pets. We used to use a diluted dish soap sprayed on the siding to keep the boxelder bugs off, might work on the spiders.

Tempo rocks for controlling insects.

Its expensive, like $35.00 for a pint, but you only use a tablespoon or so in a 3 gallon sprayer. Spray your foundation, walls, around windows and doors etc, and its good bye insects.

Thanks for the info, Neighbor guy and reddog!
