We are not getting bit as much as we would without the service but still getting some bites. We think the spraying could be done more thoroughly. It is usually done in 5 minutes. Our observation is that not all areas are covered. For example, when spraying on the deck, it is only done a little bit under the table and not the entire floor or railings. Perhaps, our expectations are higher but think more attention to all areas would have a greater chance of preventing any bites.
