Of course, we live in the country and we fight a constant battle with all kinds of varmints ... After Paula and her family left last year I called my exterminator and had him come and examine the bedrooms. He suggested that we might have fleas because people bring the eggs in on the bottom of their shoes, so we changed our policy regarding shoes in the house, and now we ask our guests to remove shoes before entering the house. This seemed to solve the problem as we did not have anyone other than Paula's family who had bug bites ...... This year, we have also had no one mention bugs in the house, so I am indeed so very sorry that Paula and her family have had bug bites at our house !!! I've checked all of the bedrooms and called the exterminator again after Paula's family left. He did not find any fleas or other bugs, but he treated the upstairs rooms never the less. Paula and her mom climbed the stairs to the fire pit and I'm wondering if they got bug bites on the pathway ...... We DO have bugs outside .... I leave bug spray in the kitchen for our guests to use if they are sensitive to getting bitten ..... Anyway .... I am so very sorry about the bug bites for your family !!!
