Use peanut butter to dissolve gum.

Peanut butter contains oils that can penetrate and break down the polymers in chewing gum, reducing its adhesive properties. Applying peanut butter allows these oils to interact with the gum, making it less sticky and easier to lift from the carpet. The effectiveness of this method lies in the oil's ability to weaken the gum's bond with the carpet fibers. It's a popular home remedy, though it requires a follow-up cleaning to remove the peanut butter residue itself.
