Mosquito division is for youth who are 10 and 11 years of age, and is the first division in which players begin to pitch the ball. A real baseball is used for the first time. In addition, a catcher is used and round robin playoffs follow the regular season. Players are not permitted to sit out for extended periods of time. All players are kept in the batting lineup and rotated by position.
Teams are usually 12-15 players. At this level, games will be defaulted if the required number of players are not at the field at game time. Eight players are needed to start a game and seven to finish.
Games are played Mondays and Wednesday nights at St. Peter's Field at 6:00pm and 8:00pm.
Mount Pearl Minor Baseball recommends that when one team is short players at the beginning of a game, that they borrow players from the opposition, or both teams may be combined to play a game. A practice session may also take place instead of a game.

Fair Play Rules for Coaches:
Coaches will be issued a score book. They must set their batting order at the start of the year. Once this batting order is set, the player who is next to hit after the last out of the previous game will start the next game. If a player does not show up for the game then he will stay in the same spot in the batting order but crossed out for that particular game. Coaches should use the first three games of the season to finalize the batter order. Batting order may be reset for playoffs.

In the Mosquito division, the collision avoidance rule has been modified to ensure the safety of the catcher and the base runner. This rule states:
