Sadly enough, this company promises great work and customer service, however, you will receive neither. We have 2 properties located in the Lock Haven area. One is a log home, one is an older frame home. Both homes were contracted through Mark's Pest Control. An example of what we dealt with was just this past weekend. We had wasps, lady bugs and another unrecognizable bug all over the properties. You couldn't sit and not have something flying all around you, there is always great activity, even after Mark's application of the chemicals he uses. After contacting them, I can share with you that Mark's Pest Control does not care about pest control, period. Unfortunately, we've wasted our money and our time. We've never written a review before, but felt it was necessary so others don't spend their money needlessly. Don't use Mark's Pest Control, ever.
