Tips for Mosquito Prevention
To protect against mosquitoes and reduce exposure to a mosquito-borne illness, Terminix recommends the following steps:

• Add mosquito traps. Well-designed mosquito traps can reduce the number of host-seeking mosquitoes that affect individuals trying to enjoy outdoor spaces. Mosquito trapping should be used in conjunction with a comprehensive integrated mosquito management plan, using multiple tactics to control mosquitoes both in their immature and adult life stages.
• Tip and Toss. Remove standing water from containers weekly. Female mosquitoes of every species need water to lay their eggs. An item as small as a bottle cap can hold enough water to support the development of mosquito larvae.
• Reduce breeding areas. Eliminate any standing water after rainfall. Common hot spots include gutters, downspouts and low-lying areas, but don't forget about dogbowls, kiddie pools, bird baths, etc.
• Use EPA-registered repellents such as DEET. The higher the percentage, the longer the protection.
• Work with a trusted, local pest expert. Trained professionals can recommend an integrated pest management plan, providing solutions to address the problem at the source.
