Roaches in appliances

[Matthew C. Frey]

I just bought a place and found German roaches in the dishwasher. We had the house professionally sprayed and a follow up spray is in a few days.

While we were cleaning, we saw that two of them were inside the control section of the range walking over the time. They were under the plexiglass.

If they’re in that deep, I assume I have to disposed of the range. Is there anyway to get them out?

If the right answer is to get rid of the range, should I assume they’re that deep into other appliances (dishwasher, microwave, refrigerator) and dispose of them as well?
