How Big A Hole Can A Squirrel Get Through?

If you’re wondering how big a hole a squirrel can fit through, it’s important to know that a typical squirrel’s head is only about one-and-a-half inches across. This means that a full-grown squirrel can squeeze through a gap about one and a half inches wide. However, if you’re preparing a hole for a larger animal, you should consider using a smaller hole and increasing the food content.

Some people believe that a grey squirrel can fit through a hole as small as a quarter. This is simply not true. Squirrels can fit through holes as small as a quarter inch. If you’re building a house, you can try to seal the hole with 1/2-inch wire mesh, sheet aluminum, or wood. Remember, though, that squirrels will chew through these materials, so make sure you use a sturdy material to keep the rodents out.

Squirrels’ Hole Size

A quarter-inch-deep hole should be small enough for a grey squirrel to squeeze through. However, if you’re building a house, you’re better off using a small-sized hole. A one-inch hole is a minimum size a grey can squeeze through. In addition to this, the larger the hole, the larger the animal will grow. While a quarter-inch-deep hole is too large for a grey to fit through, it may still be large enough for a squirrel to squeeze through.
