EcoHealth Alliance President, Dr. Peter Daszak discusses the expanding urban infestation and the growing number of pests in our cities. Bed bugs feed exclusively on blood and Toronto is ranked as the most infested city in Canada. Coyotes are now stalking our cities, seeking their next meal in our very backyards. Termites are now eating through cities costing North Americans more than one billion dollars every year. Cockroaches have been around since prehistoric times but their numbers are increasing as our city populations expand. New York City is being overrun by rats and it is now estimated that there are at least as many rodents as people. The mosquito has been relentlessly seeking our blood for millions of years and carries West Nile virus.
