BEASTS BEGONE! Appendix A: Animal Identification

Red Squirrel

Small (less than 1 lb.), reddish brown above and white below. Often a black stripe separates the two colors. Diurnal (active during day). Frequent invader of attics, wall voids, and miscellaneous crawl spaces. Also can become trapped in chimneys.

Access Routes

Trees and branches within 10 feet of the roof; electrical utility lines; fire escapes; certain types of siding; brick chimneys; downspouts (occasionally).

Entry Sites

Usually high on the building; holes in fascia boards of eaves, dormer tie-ins, architectural returns, and similar sites along the roof line; vents (roof, soffit, gable, fan); uncovered chimneys; deteriorated roofs, eaves, and walls. Will also enter holes near the foundation and crawl spaces and wall voids via attached garages. Entry holes can be smaller and more difficult to find than those of the gray squirrel.


Very vocal; distinctive calls; diverse repertoire includes chatters and clucking sounds and pitch is higher than that of gray squirrel. Scampering; gnawing.
