West Nile virus cases reach a record high this summer.

According to the Centers for Disease Control and Prevention, the number of cases in the US jumped 25 percent in one week, making 2012 the worst year for the virus since 2003.

As of Wednesday, 2,118 cases have been reported across the country, including 92 deaths.

Colorado has seen 33 confirmed cases and two deaths in Montrose as a result of West Nile.

Reports say cases are especially bad this year thanks to the mild winter, which brought on an early spring and hot summer. The weather creates prime breeding conditions for the type of mosquitoes that carry West Nile.

In a bad mosquito season, bug spray can be your best friend.

Consumer Reports reviewed several repellents that protect against deer ticks and two common types of mosquitoes for eight hours or more.

The top bug spray on their list is "Off! Deep Woods Sportsmen II." It contains 30 percent deet and will cost you $1.25 per ounce.

Rounding out the top four are "Cutter Backwoods Unscented," "Off! Family Care Smooth & Dry” and "3M Ultrathon Insect Repellent 8.”

All four received a score of 98 on the Consumer Reports chart but have varying levels of deet.

According to the report, the Environmental Protection Agency said deet is safe when used as directed but should not be used on infants less than two months old.

When applying your bug spray, they recommend using your hands to apply it to your face-- avoiding your eyes and mouth-- and be sure to avoid any cuts.

Use only enough to cover exposed skin.

Avoid spraying repellents on to your clothes, as they can damage leather and vinyl and even stain synthetic fabrics.
