Yes, in some cases if your damper is left open, animals can come down your chimney. In these instances, it’s more likely that they have fallen in while looking for a safe spot rather than entered your house intentionally. Leaving your damper closed or installing a chimney cap can prevent animals from coming inside.

Natural swimming pools are designed to deter pests, including mosquitoes. While any body of water can potentially attract pests, the natural filtration system keeps the water clean and constantly moving. Mosquitoes specifically are attracted to standing water, so the continuously circulating water in a natural pool makes it an inhospitable environment for them.

Birds are often averse to certain strong scents. For instance, the odor of predator urine, such as that from foxes or hawks, can deter them. Similarly, birds may dislike the pungent aromas of garlic, onions, and chili peppers. Essential oils like peppermint, eucalyptus, and citrus can also be effective in keeping birds away. However, it's important to note that individual bird species might react differently to these scents, so it might require some experimentation to find the most effective repellent for your specific situation.
