Some info on Boxelder bugs ..

I guess the photo is not showing the correct colours if you say it matches yours perfectly Kyla? They should be red with black legs.

Although they are said to use host plants other than the Box Elder, they would more likely use that if it was available.

they make their homes in box elder, maple and ash trees during warmer seasons and migrate into buildings and homes to find shelter for the winter. Adult bugs live and breed on the leaves of box elder trees, laying their eggs in spring.

The adults may hide in places around houses, but nymphs don't have wings.

Box elder bugs inhabit maples and ashes, and seed-bearing box elder trees, in warm seasons

During warm seasons, box elder bugs make their homes on the leaves of ash, maple and box elder trees. These trees provide safety, nourishment and a breeding location for the box elder bug.

Adult box elder bugs lay their eggs inside of host trees or on their leaves.

Box elder nymphs appear similar to their adult counterparts, but are smaller than fully mature specimens

I would have thought Boxelder bugs had fully matured by now:

Most of the nymphs of the second generation grow to full size in August and September
