According to NBC Philadelphia, Asian tiger mosquitoes are a tough go for Paramus exterminators and residents. This invasive species of mosquito is aggressive and is known as a vector for West Nile Virus. Local authorities blame homeowners for keeping standing water on their properties. Even just a small container of water is enough water for mosquitoes to hatch in. To prevent these mosquitoes, and all mosquitoes, from infesting your property, you need to make sure that no standing water is available. It's important for neighbors to work together to prevent mosquitoes, as standing water in one yard means mosquitoes next door.
