Drive to a "different area"
Sorry to seem harsh, but a 10 year old doesn't just stop eating this time of year for no reason. Since you haven't given us any additional information about it's "lifestyle" we can do nothing.
I will not tell you how to force feed a gecko "just cuz". If it is impacted or parasitic you could make the problem much, much worse. Take the gecko to a vet, call a vet, do what it takes to care for your responsibility. Force feeding with no information about the underlying condiion is a huge no-no.
