I moved into a property with that had issues, And for 3yrs had different companies and it didn't help much with the once amonth visits, But after finding Walker Pest Exterminators I may see 1 now and then. They come out every 2wks until the get them in control and that makes the biggest difference, The techs are polite and professional. The first payment might be a pinch but it is really worth it. For the health of your family/ knowing your place is clean.
