is my body wash causing me to have a rash and be more susceptible to bug bites?

recently i have developed small red bumps that itch on sun exposure on my upper arms. i also have had a lot of bug bites on my neck, upper back, upper chest, and shoulders. i have not had this problem in the past (or if i have, it has been on a much lesser scale). i also recently changed body wash because i liked the tropical scent of the new one. could this new body wash be the cause of my skin problems? any suggestions on how to prevent bug bites and to help heal the ones i already have?
