Anyone have a recommendation for an exterminator that isn't insanely expensive? We just moved in to our house last week & shortly after found out there's a roach infestation. We found a nest in the bottom of the refrigerator so we removed the refrigerator from the house but we're still finding roaches even though we sprayed. We are not dirty people & it's making me feel like we are.. Money is just really tight right now & I really need to get this problem taken care of. Thanks in advance!!
