Is it permissible to eat at a close family's home if he works for an insurance company and he sells insurance.

The income derived from the sale of insurance is Haraam. Therefore, avoid eating at his home.

In doing so, you should apply wisdom and diplomacy as the person is a close relative. The good relationship may be used as an opportunity to advise him to change his source of income.

and Allah Ta'ala Knows Best
