When we purchased our home, one of the first things we installed was a screen door leading to the front porch. It's a great way to let the fresh air in, but a hindrance to our avid grilling habits... have you ever tried to juggle a plates full of fresh-off-the-grill foods while coaxing your screen door open?
We left the back porch door alone as it leads to a screened-in porch. Sadly, this was a mistake as "screened-in" doesn't necessarily mean bugs out.
Little did I know then, Bug Off Screen (the remedy to all our screen woes,) was readily available.
