It might be worth it to call the exterminator if you want it done quickly and with something that won't harm your pets. I'd explain the delicate nature of Bullys to him / her and choose one who advertises that they use chemicals not harmful to animals including wild ones. There are chemical free ways to deal with it but I'm thinking they take too much time for this situation. Doing it yourself not only exposes you to the chemicals without proper protection but you probably don't have the chemical knowledge to choose an appropriate one. Also, you're more likely to miss some place. If the pro misses they usually come back and fix it for free. Have them get rid of any ticks in the yard while they are at it.
