Wild Animals/coyotes


We are having a coyote problem in Chatsworth CaI.Can not kill them.They have  killed 80% of all pets in our neighborhood.Is there a sound frequency that would scare them enough to keep them away?Any suggestions would be appreciated. Thank you.

Hello Doug

Thanks for your question. I also wish to thank the authors of the websites I've used.

I'm sorry to hear about the coyote problem. I've been reading that coyotes are very adaptable and have taken over some of the territory formerly occupied by wolves.

Nicole Marie, Zeal, Jordansmall, Flickety and 4 others (http://www.wikihow.com/Keep-Coyotes-Away-from-Campsites-or-Homesteads) have compiled various ideas to deter coyotes. Their ideas of using sound include motion-activated and the new Anti-Coyote sound system, which emits replicated cougar sounds and may keep coyotes away. http://www.ehow.com/how_8357084_scare-coyotes.html suggests using high-pitched screams, but please note that coyotes may make high-pitched sounds that can attract coyotes.

http://www.fws.gov/sachuestpoint/images/News/DeptofWildlifeTips-ExclusionsDeterr includes using sirens run by a timer, but http://www.ipm.ucdavis.edu/PMG/PESTNOTES/pn74135.html says that coyotes quickly adapt or habituate to sounds and other deterrents and may be impractical for use in suburban areas as they can disturb your neighbours. Nightpests.com (http://nightpests.com/coyote.htm) may be able to help.

It doesn't seem that there are any totally fool-proof methods using sound, unless the claims of Nightpests.com are true. I haven't used this company and I can't verify its claims.

I hope this helps.

All the best

I can answer questions about wild mammals and other animals, as well as extinct animals and zoos. I am not an expert about every animal species. I can look up information from books and the internet, but can't verify if all the information is true. Please don't ask questions about: 1. Pets. I am not a vet. Please contact a vet if your pet is ill. You may need to spend some money if you want your pet to live. Don't get a pet if you don't know how to look after it and if you can't provide it with the space, food and possible companions that will help it live a healthy life. Don't take animals from the wild, unless they are ill and/or injured and you can protect them until a wildlife charity can help. It is cruel to take animals from their parents, especially if the parents will look for the babies, while putting their other babies at risk. You may be breaking the law by keeping wild animals or you may need a licence to look after some species. Please check with a local wildlife group. 2. Eggs: Please don't remove eggs from nests. The mother birds provide the right temperature for the eggs and won't sit on them if the temperature is warm enough for them to develop naturally. It is illegal to remove eggs of some species and, unless you have an incubator or a broody hen, the egg may not develop. If you are allowed to touch the eggs, you can candle them to see if they are fertile. If theys aren't fertile, they won't hatch. 3. Fights: Please don't ask about fights between different animals. These questions assume that individuals of two species fight each time they meet and that one species will always be victorious over another. This is untrue. There are cases where a live mouse has been fed to a venomous snake, bitten the snake leading to the snake's demise. 4: Diseases: Please ask doctors or other medical experts about diseases that you may catch from animals. I can't advise on how to deal with viruses, bacteria etc.
