While most people enjoy spending time outdoors during the summer, they don't particularly like spending their time with the bugs. A new survey for Orkin shows that flies top the list of the most annoying pests, with 45-percent admitting it's the insect they see most frequently around their home.  Two out of five people say they have a lot of stinging bugs near their house, and 39-percent have an issue with mosquitoes.  Health and safety concerns top the list of reasons why people don't want the pests around, with 43-percent saying the bugs could "bite, sting, or attack" them.  But 41-percent add that they simply find the insects a "nuisance." , bees, and wasps cause the biggest health concerns.  Mosquitoes can carry the West Nile virus, while a number of people are allergic to wasps and bees
