Greetings, welcome to the Forums.
Pipal Tree (Ficus religiosa), also known by many other common names including Bodhi Tree and Sacred Fig, is an evergreen Fig in the Mulberry Family (Moraceae), native to southern and southeastern Asia. It is widely grown in tropical regions both for ornament and its religious significance in both Buddhism and Hinduism.
Yes, do treat for Scale (Coccoidea, Hemiptera) with neem oil, horticultural oil, or insecticidal soap.
It would be interesting to know how many hours of direct sun this bonsai receives each day.
