Drought blamed for West Nile spike in mosquitoes

You may not be seeing a lot of mosquitoes out, but the ones you do see are more likely to have the West Nile Virus.

More than 400 samples of mosquitos tested positive for West Nile this year. That's almost three times as many as last year.

The county says its because the drought has forced birds and mosquitos to compete for the same water and they're infecting each other with the virus.

The heat and drought are also driving insects into unexpected places. At Memorial Park, bees have taken over one of the water fountains in search of something to drink. Insects are seeking out things like water fountains and faucets because natural water sources have dried up and they are aggressively defending any water they find.

Hornets, fleas and ticks are also worse than usual for the same reason.
