Disadvantages of Size in Squirrels

Squirrels can be a nuisance because they eat your food and damage your property. They are also known to attack humans, so keeping them away from your home is essential. However, if you do have a squirrel living in or around your home, there are some steps you can take to discourage them from coming back. 

For starters, make sure your food is placed in a squirrel-proof container. Secondly, install bird netting or a squirrel-proof fence around your property to keep them out. If that doesn’t work, you can try using a squirrel-proof trap or repellent. Last but not least, size does not always equate with strength – sometimes, the biggest squirrels are the weakest!
