Why don’t you pick up dead birds?

The California West Nile Virus Hotline was established to help California track the movement of West Nile Virus. Occasionally, they will ask for a sample bird to be held for pick up and then contact the City of Riverside to pick up the bird. Otherwise, after reporting the bird to the Hotline, the bird may be disposed of with the regular household trash. Refer to Dead Birds to learn how to safely dispose of dead birds or animals.

Can someone come out and identify the bees in my backyard?

No. Africanized Honey Bees are a hybrid between African Bees and European Bees. They are relatively the same size and have the same identifying marks, therefore only scientists in special labs can identify bees. Because of this, it is a good idea to stay away from all bees. Refer to Africanized Bees to learn more about Bee safety.

What can I do to protect my pool or ornamental pond from mosquito breeding?

Keep swimming pools clean, aerated and chlorinated. A bacteria called "BTI" (Bacillus thuringiensis) can be used for mosquito larvae control in standing water. Aerate artificial ponds to prevent the surface of the water to remain unbroken. Avoid massing aquatic plants together in artificial ponds. Mosquito larvae can hide from the fish if the vegetation is dense. Stock artificial ponds with fish that eat mosquito larvae such as mosquitofish or guppies. Refer to Mosquitoes for more information on how to protect you and your family from mosquitoes.

How can rodents get into my house even after I block all entrances from the ground?

Rodents can climb along tree branches or palm fronds to reach the rooftop, from there, they can usually find a way in through vents, pipes, etc. Don’t forget to cover those as well. Keep trees and palms trimmed away from the house.
