We have some bats around the house but I really wish we had more! They eat mosquitos and we have tons of mosquitos on our property for some reason. My youngest son and I cannot even go out into the yard without being eaten alive-abd we do not even have any water around us. We have a lot of trees so I guess this is why we have so many but Jacob and I can be covered in Off Deep woods or Skin So Soft green can stuff which everyone swears works best and can still get lots of bites on us. I really hate it because we have two huge decks and a beautiful property and I would love to be able to sit out on the deck and relax but we can't be out for 5 minutes without getting bitten alive. My fiance and my oldest son do not have this problem-they rarely get bitten.
