2010 Termite Swarm Alert Map
Terminix Pest Control have released an animated Google Map to show how "termites swarm across the U.S. looking for places to establish new colonies". The map shows an animated time-line of 2009's termite swarm progression across the country.
It is possible to search the map by zip code to get projected termite swarm dates and threat levels for your home. Unsurprisingly the site encourages you to protect your home with Terminix.
