Nursery

Nursery is the first nest building. It enables the purchase of larvae as well as various larva-related upgrades.

Like all buildings, nursery is lost upon migration.

Larva Shop
You can purchase larvae up to the level of your highest level ant. Larvae can be purchased for food or sugar. As you purchase more larvas, their food price increases.

Nursery Upgrades
Unlike most buildings, Nursery can be upgraded an indefinite number of times.

Upgrading the Nursery increases how much food can be produced while the game is closed. For example, if you have a LV2 Nursery, then offline food production will stop once you have accumulated 30 000.

It's possible to bypass this limit by watching the idle production ad that comes up when opening the game.

Nursery Upgrades
Nursery upgrades cost food and are reset upon migration.

There is no limit to how many times you can purchase each upgrade, but each purchase will increase the cost of the upgrade. Once the effect cap is reached, new upgrades will provide no additional benefit.

Larva spawn speed upgrade increases the rate at which free larva spawn on unoccupied tiles.

Larva discount upgrade decreases the food cost of larvae. This effect is not additive. Each new upgrade decreases the cost of larvae, taking the current cost as 100%. This means that the first upgrade will give you the most benefit.
