Can I still control rodents without using anticoagulant rodenticides?
Yes. The most effective rodent control program uses exclusion techniques (sealing the places where rodents enter your home) and sanitation (removing plants and objects that attract rodents and potential habitat such as ivy or wood piles); animal removal is used only when necessary. More information on controlling mice, rats and field rodents is provided on the University of California Integrated Pest Management website.
What are second generation anticoagulant rodenticides?
Second generation anticoagulant rodenticide products contain the active ingredients brodifacoum, bromadiolone, difethialone and difenacoum. These products can not be legally purchased or held by the general public and can only be applied by certified pesticide applicators. These chemicals prevent the clotting of blood in animals that have ingested it causing internal hemorrhaging and death. Animals (including humans, pets and non-target wildlife) that eat the chemical or eat rodents that have eaten the chemical will become sick and die.
How are anticoagulant rodenticides harmful to the environment?
Throughout California, the use of poison baits to control rodents has injured and killed hundreds or thousands of wild animals and pets. Predatory and scavenging birds and mammals like owls, hawks, raccoons, bobcats, mountain lions, foxes, skunks and coyotes that eat dead or dying rodents that have consumed these baits will also be poisoned. Pets will also eat dead or dying rodents and unprotected bait.
Are there benefits to having coyotes live near Davis?
Coyotes are considered an apex predator which contribute to maintaining the health of an ecological system. Apex predators help to regulate the populations of other species that, in high numbers, may harm the ecological function of local habitat areas or become a nuisance to adjacent residential areas. Such species include hares, rabbits, mice, rats, raccoons, skunks, feral cats, wild turkeys and Canada geese.
Are coyotes a threat to my safety or the safety of my family or pets?
Coyotes naturally view humans as a threat and avoid them. The rare occasions in which they do attack humans typically involve unattended infants and toddlers. Even more rarely do such attacks result in death. Coyotes that have habituated to human presence via direct (handouts) or indirect (pets, garbage, pet food, etc.) feeding may become more aggressive toward humans. Such animals require hazing (i.e. scare conditioning) to reestablish their fear of humans. Coyotes that become overly aggressive and/ or attack humans need to be lethally removed.
Coyotes view small pets as potential food. Coyotes are present in our region and will enter urban areas in search of food when resources are available. Such activity is especially common near the urban to open space interface. Pet owners who are concerned about their pet being eaten by a coyote (or killed by a car or another wild or domestic animal) should take precaution by not allowing their pets roam freely at night.
How does the City respond to coyote sightings?
The City's Coyote Management and Coexistence plan identifies four levels of incidents with coyotes and the appropriate management action:
Level 1: A coyote that has been involved in an investigated and documented unprovoked attack on a human.
Action -Targeted education and hazing needed, public awareness of incident and circumstances discussed. Lethal response may be appropriate.
Level 2: A coyote that has been involved in an investigated and documented provoked attack on a human with no pet involved.
Action -Evaluate circumstances and human safety, provide education and hazing training, enhance public awareness of incident and circumstances. Lethal response may be appropriate.
Level 3: A coyote is involved in an incident(s) and/or preys on attended domestic animals.
Action -Monitor coyote behavior. Education and hazing needed, public awareness of incident and circumstances discussed.
Level 4: A coyote appears to frequently associate with humans or human related food sources, exhibits little wariness of people, and/ or preys on unattended domestic animals.
Action -Monitor coyote behavior and implement hazing if needed. Education and public awareness of incident and circumstances discussed.
Can I trap and relocate wildlife from my home?

What should I do if I encounter sick, injured or abandoned wildlife?
Sick or injured wildlife should be approached with caution. Animals that are sick or injured are particularly defensive and likely to bite if handled. Bites from wildlife are painful and may transmit harmful diseases. Depending on the species of animal, the following contacts should be able to lend assistance:
Can I prune or remove a tree without harming wildlife?
Ideally, tree pruning should be scheduled to occur outside of the breeding season. The breeding season typically occurs from Feb 1 thru Aug 31, annually. However, there may be a need to prune trees during the nesting season. Always check before you cut. Check the tree from top to bottom, including the main trunk. Look for stick nests, holes in the trunk, and bird activity. If you see a nest or cavity, wait to prune until after the breeding season. If you are uncertain as to whether or not something is a nest, error on the side of caution and wait to prune until after the breeding season. The City's Wildlife Resources Specialist is also available to help make a nest determination.
How do I dispose of a dead animal found on my property?
Dead animals under 10 pounds can be placed in a bag and disposed of in the refuse bin. Larger animals may be buried or taken to Yolo County Animal Services in Woodland. Two or more dead animals at the same location may be an indicator of a disease outbreak or environmental hazard. Please report such occurrences to the City of Davis Wildlife Resources Specialist.
