DIY animal removal is rarely a good idea and is not advised for many reasons. First, these types of animals can carry diseases and, therefore, pose a health risk to you, your family, and your pets if mishandled. Second, depending on your city or municipality, it may be illegal to remove or handle wildlife yourself. 

Sealing your home against these animals yourself is also a bad idea. Trapping an animal under your house will cause odor and insect problems when it passes away. 

Using audio and visual methods to discourage birds might work initially, but birds tend to acclimate to them over time. While chemical deterrents can show some effectiveness, their results can be inconsistent. Some may dissipate too quickly, and there's a risk they might cause unintended damage to your surroundings. Additionally, birds might become immune or resistant to the impact of such treatments.

Once the animals and their young are out of the house, remove the nest and locate any entry points. Some may be difficult to find because some animals can fit through very small holes. Once you’ve located as many entry points as possible, use materials such as metal or masonry to block off the entry. Ideally, you should choose materials that most animals cannot chew through. Create a one-way door or flap to allow animals to leave but not return. Additional methods include using repellants designed to make an area unappealing to the types of animals that find your home so inviting. 

Vinegar can keep some animals at bay, like deer, rabbits, foxes, and raccoons. Keep in mind that your household pets, like cats and dogs, also don’t like the smell of vinegar. You can soak rags in white vinegar and put them up around your garden beds to keep the pesky critters from eating your plants.
