Full Answer

Leaf nests are built using a foundation of twigs that are woven together and covered with leaves and moss. These nests are typically located where branches meet a tree's trunk or where an intersection of branches provides better balance and support for the nest, according to West Virginia Wildlife Magazine.

Nests built in hollowed out tree trunks are used as nursery nests for squirrels giving birth to babies, and they are also used for better protection during the cold winter months. In urban areas, squirrels may skip building nests in trees and head for the warmth of buildings, which can lead to significant damage in attics and electrical wiring systems.

    At night, squirrels conclude their activities by retreating to nests, which are primarily built in trees.

    What are some smells that squirrels hate?

    A:

    According to RedBeacon, squirrels hate the smell of peppermint and spicy peppers. Peppermint gives off a strong aroma that discourages squirrels from venturing into an area. Spicy aromas, such as that from cayenne peppers, serve as a natural squirrel repellent. Jalapeño peppers mixed with vinegar and water serve a similar purpose in keeping squirrels at bay.
