According to SMCMVCD, the chemical to be used is called Zenivex, a formula that is EPA approved to be safe for use in all urban areas. No precautionary measures need to be taken by residents within the fogging area.

They're also asking for people to keep an eye out for dead birds and squirrels, a sign that West Nile is circulating. Sightings should be reported to the West Nile hotline online or by calling (877) 968-2473.
