Dot Urbanism

Intrigued by the colorful dots he found spray-painted on the streets of San Francisco, always near drains, Nick Foster began photographing them.

He soon learned that these marks are not some emerging genre of street art—at least not intentionally—but are, in fact, quasi-Pynchonian signals left behind by the San Francisco Mosquito Abatement Courier Team, or SFMAC.
Formed in 2005 following the rapid increase of West Nile Virus in California, this band of pest controllers cycles around San Francisco dispatching sachets of Vectolex into the drains to kill the little biters before they breed. After each drain is treated, the courier sprays a little dot of paint to mark it as completed—this season’s color is blue.
Like full-spectrum hieroglyphs, these spray-painted dots are "infrastructural forensic evidence," in Foster's words, marking the ritualistic elimination of insects from urban space.

Wendy MacNaughton did a beautiful illustration of this last season, when the color was orange: http://wendymacnaughton.blogspot.com/2011/05/may-10-2011.html

Reminded me (before I read through and understood why these paint marks are left) of a story from Kurosagi Corpse Delivery Service called X+Y=Love, from Volume 3, where spray paint markings are left in cities to help track people down for similar reasons that these insects are being sought...

While I would strongly recommend a buy, you can read this one here: http://manga.animea.net/kurosagi-corpse-delivery-service-chapter-14.html

In NYC, contractors use a similar dot system to mark conductive paving elements -- manhole covers, sewer gratings, valve covers, etc -- after they've been checked for stray electrical current. (I noticed this after a series of accidental electrocutions caused by energized street furniture several years ago.)

I've worked in San Francisco for 10 years, but this very morning was the first time I noticed these dots. Thanks for the timely explanation!
