Ants and Aloes
Ants on their own do not cause any damage to Aloes but due to their propensity for all thing sweat they can cause severe damage when they partner up with another common garden pest namely mealy bugs and aphids. See the relevant sections for treatments.
Ants and aphids have a symbiotic relationship, the ants afford protection to the mealy bugs in exchange for a sticky sweet substance, honeydew, that they excrete. Ants can actually be seen carrying aphids from plant to plant.
Because aphids are sap feeders they may transmit serious diseases between the Aloes and due to the fact that these pests puncture the plant they may cause the plant to rot if they are left unchecked, which is often the case as they hide in between the leaves where one cannot see them. It is wise to inspect your Aloes closely every now and then for these pests as they are often only noticed when the rosette collapses from rot.
