Killing a squirrel really isn't what you should be aiming for with wild animal control, and there really is no need for it. There isn't a poison you can use to kill the animal, because one doesn't exist for squirrels. You would need to use a lot of rat or mouse poison to do the job, and even then you're only guessing the figures. You might leave the animal seriously maimed rather than dead, causing it to have an excruciatingly long and painful death. You're also putting other people and animals in danger also. Household pets could get access to the poison, as could other animals such as mice, rats, pigeons, etc. When the pets in the neighborhood go after these animals, they will then consume the poison because there is poison in the squirrel / rat / mouse. We do not believe in killing squirrels when we remove them from a property because it causes more problems than it solves. Instead of looking at killing the animal, you'll often find that exclusion devices are more effective, giving you a way to encourage the animal to leave and not be able to get back in. Then you don't need to resort to such drastic measures as killing the creature.
The squirrel may infest your home, but they are not safe as they may harm, your pets bite you or even transmit some diseases to your or even your animals. On the other side, they like gathering around the stores where they damage food kept. Also, they destroy the fruits as well as vegetables in your garden. While inside the house, they, may spread waste from wastebaskets all over the house or even damage wires. However, Killing a squirrel can be humane but only if you take steps to induce little suffering as possible. There are few questions about legality before you kill a squirrel, you should consider the law of your country. The meaning of human and cruel may vary from one place to another, but there are some common principles to keep in minds, if you happen to trap a squirrel, do not every try to use the inhumane ways to get rid of it, always consider the humane options
There is one method approved by the American Veterinary Medical Association that is the use of Asphyxiation by CO2. The method uses the household, materials. This method is done by vets and not ordinary people. Therefore, you should look for a professional to do it without causing undue pain as well as suffering for the squirrel. This is an easy method, but when done appropriately it is the most humane. Before you begin, the methods involve mixing baking soda with white vinegar to form a gas which will asphyxiate the squirrel. Besides the vinegar and baking soda, you will; be required to prepare a sealable plastic container, seal plastic bag a pipe to connect the tap plus a separate container to mix the vinegar and baking soda, for example, a jug or glass. You will require fasteners, ties, and clothes to secure altered containers. The plastic vessel is the euthanasia for the squirrel. The gas will be produced in the plastic bag which is the CO2 chamber
When preparing the CO2 chamber, the baking soda is placed at the lower end or bottom of the bag. Then, make another separate container of the vinegar without spilling. Later mix the two baking soda and vinegar, and the result will be (CO2) a form in which the squirrels cannot breathe. The ratio in which you mix the two mixtures will depend on the size of the containers you are using. Getting the precise concentration of CO2 is imperative to its humaneness. You are supposed to create about 30%-40% CO2 concentration in the euthanasia vessel to effect the rodent to lose consciousness.
When preparing the euthanasia chamber, you should ensure the squirrel handlers are safe; you are supposed to place the rodent into an airtight plastic container the best containers which work better are the Tupperware. Also, you may add some nesting material to make it a little comfortable and perhaps put the squirrel slightly more at ease. Lastly, you are supposed to pour the vinegar over the baking soda. This is after everything is secure, pour the white vinegar carefully over the baking soda. This will form CO2 which will slowly travel via the pipe to the plastic container. You are supposed to place about half of the vinegar and then observe the squirrel inside the trap. It will slowly pass out and die after it becomes unresponsive, pour the rest of vinegar over.
