A squirrel nest, commonly known as a drey, is a dense, spherical structure made of interwoven twigs, dry leaves, and grass, usually assembled in the forks of a tall tree. These nests provide cover from predators and insulation from the weather. Squirrels are drawn to residential areas by consistent food supplies and the necessary elevation for protection. While a tree nest is natural, its proximity to a home can create issues if the animals use branches to enter attics or soffits.
Understanding Wildlife Protection Laws and Timing
Before attempting any removal, determine the nest’s activity level and check local wildlife protection regulations. Most jurisdictions prohibit disturbing active nests, especially those containing dependent young, as this is considered inhumane harassment. Squirrels typically have two breeding seasons annually, meaning young may be present from late winter through spring, and again from late summer into early fall.
The first litters are usually born between February and April, and the second between August and September. Young squirrels remain dependent on the mother until they are about ten weeks old. If a nest is active, the only ethical and legal course of action is to wait until the young have fully vacated the structure and are self-sufficient. Removing a mother during this time will lead to the death of trapped offspring, which can create odor issues and attract other pests.
Identifying the Nest Type and Safe Removal
The method of removal depends entirely on the type of nest constructed by the squirrel. The most common is the drey, a visible, bulky ball of leaves and twigs high up in the branches, often near the trunk. The second type is a cavity nest, located inside a natural or pre-existing hole within the tree trunk or a large limb. Cavity nests offer better protection and insulation, especially during winter months, and their removal usually requires professional intervention.
A drey can be safely removed using a long, telescoping pole or a lightweight PVC pipe extension with a pronged end, allowing the work to be done from the ground. Before approaching, observe for several hours to confirm no squirrels are present. Gently push the nest material out of the tree fork, ensuring all debris is completely removed. Removing all remnants prevents squirrels from quickly rebuilding in the same spot. Always wear gloves and eye protection due to falling debris and potential parasites.
Strategies for Preventing Squirrels from Rebuilding
Simply removing a nest will not solve the issue if the environment remains attractive for a new home. Squirrels are opportunistic and will relocate nearby if food sources and easy access points persist. The most effective long-term measure involves habitat modification, which removes the squirrel’s travel routes and climbing ability.
Trimming tree limbs eliminates access to structures; ensure branches are cut back at least six to eight feet from any roofline or chimney. This prevents squirrels from leaping onto the house, a common entry method. To prevent squirrels from climbing the trunk, install metal flashing or a specialized baffle around the tree.
This smooth barrier should be secured around the trunk at least six feet from the ground to block ascent. Removing external food sources, such as bird feeders or fallen fruit, reduces the incentive for a squirrel to establish a territory. Exclusion techniques must be applied consistently across the property to discourage squirrels from moving to another nearby tree.
