Urgh, I would pay for pest control.
Mine & my ex's house had ridiculous amounts of huntsmen and it scared the cr*p outta me and the kids whenever we saw one. I would have done almost anything to have been rid of them.
A friend of mine actually got bitten by one in his sleep and it made him really sick for close to a week, and he was a fit & healthy 40yr old man so I was worried about what they could potentially do to a toddler... I know it wouldn't kill them as their venom isn't deadly but it is still venom and can make you sick.
I'd say spray! We spent $200 spraying here for ****roaches where they did outside as well as inside and anything that crawls up to where they have sprayed outside dies.
Money well spent in my books
