Read in-depth analysis on Pistachios and Squirrels: Fact-Checking Toxic Claims and Nutritional Myths.

Feeding wild animals is driven by good intentions, but wild populations are healthiest when human interference is minimal. If you occasionally offer unsalted pistachios, stick to strict feeding limits:

Limit offerings to a single unsalted, raw kernel once a week. Never fill a garden trough or feeding hopper with commercial pistachios. Rely instead on native nuts in their shells, such as native walnuts, pecans, and field acorns, which force squirrels to exercise their jaw muscles, naturally wearing down constantly growing incisors. Pair dry feeder offerings with clean water sources, especially during summer months, to prevent dehydration.
