Spirit mosquito pouch
A Spirit mosquito pouch is made by using a Summoning pouch on a Summoning obelisk with 1 spirit shard, a Gold charm and a proboscis in the inventory. Making the pouch earns 46.5 experience points. Using the pouch to summon a Spirit mosquito gains 0.2 experience points, and costs 4 Summoning points. If players exchange their Spirit Mosquito pouches at Bogrog, they will receive 1 spirit shard per pouch.

Pester scroll
A Pester scroll enables the use of the Pester special move for a Spirit mosquito. Using the pouch on a Summoning obelisk creates 10 scrolls.

Pester
Pester is a special move for Spirit mosquitos, which sends a mosquito to attack the enemy.

Trivia

 * In theory, a player can get 99 summoning in one trip using only Spirit Mosquito pouches at level 17 at the Gu'Tanoth obelisk. All the ingredients stack and, after creating the pouches, they can be immediately swapped with Bogrog to recover some of their shard content, reducing costs. This could also be done at any other obelisk, but then scrolls must be made. If done so the player will need to make 280,247 pouches. The costs for doing so are very high as the proboscis is worth coins in the Grand Exchange and the spirit shards are 25 coins each. Also the time needed to gather all charms is also a lot. It would take  coins for that many proboscides, excluding shards and pouches.
