Reoccurring insects bits - I came back from Mexico 6 days. I was bitten by various insects, possibly flying ants, flees and mosquitos. At first I didn t use Off , but later I realized that it didn t help. I used the Betaderm Cream(Betamethasone Valerate) .1%, and it helps a bit. I notice some bits are as if they are spread. For example, initially looks as if there were 3 bits/marks, all of the sudden it turns into 6.
