spraying ground around joists?

We are fixing some joists in a 150-yr old house and while everything is open to the ground my contractor suggested having an exterminator spray the ground. This house has never had a termite or mouse/roach problem, and I tend to shy away from all pesticide use when possible. Would you have it sprayed now? The thing is, we can’t really access this dirt again once everything is closed up. Any advice?
