Spread Rate
Easily transported via humans via shipments of plant material or in package material. Reproductives capable of flight.
5
Spread Amount
Modeling predicts a suitable range beyond the latitudinal range of 35°N and 35°S. Likely to establish where there is sufficient artificial moisture. Native to old world tropics but has invaded and established in arid climates and at high elevations.

Damage
Notes
Score
Ecological
Poses a significant threat to biodiversity and abundance of native species in introduced areas. Known to reduce native bird, reptile, and crustacean populations and displace native ant species.
4
Agricultural
Tends honeydew producing insects, mostly scale leading to increased pest populations. Disrupts biological control. May injure agriculturally-important animals that are in infested areas.
3
Infrastructure
Known to invade human infrastructure.
1
Cultural
Negative affects on gardening and recreational use of infested areas.
2
Health
Spray formic acid for defense.
