Each day, Brandon Pollard ventures out to inspect what he calls "collateral damage" from the war on West Nile virus. "We've been going around and checking our bees, making sure they have not been compromised from the spraying," Pollard said. He's an urban beekeeper with the Texas Honeybee Guild. Pollard maintains dozens of hives across North Texas, in areas where fogging for disease-carrying mosquitoes has been most intense. "We've lost thousands of bees," Pollard said. Pesticides act like a deadly neurotoxin to bees. And, though bees stay in hives, chemicals can still seep in.
