Not a single bite in Costa Rica for me, Jack, Liv, and Mike. The teens got a couple but they weren’t as great about using these options. But world of difference since our last trip to Costa Rica we got eaten up and ended up having to go to urgent care with Ella for a nasty reaction to a bite. Jack and Liv used the stickers - and again ZERO bites!! I also put the No Bite Me cream on Liv’s arms and legs when we were hiking. Teens and adults mainly used citronella bracelets (Ella started also using stickers). Teens and adults also sprayed with Grand Tongo for more adventurous outings. It’s the absolute best picardin bug repellent!! No nasty scent and no sticky residue. It’s luxury!!
