NAPRA Ireland risk assessed
Small mammal with slender body and short legs. Pointed head and small ears. Thick muscular tail. Fur is short and ranges in colour from pale to dark brown with gold flecking. The body is paler underneath. Eyes are amber or brown in adults and blue green in juveniles. Males are larger, stockier and have a wider head (Csurhes & Fisher, 2010).
An opportunistic carnivore, it eats a wide range of foods including mammals, birds, eggs, reptiles, amphibians, fruit though it is mainly an insectivore (Lutz, 2003). Has caused the extinction of many bird, reptile, amphibian and mammal species in its introduced range (European Commission, 2015) particularly on islands (Csurhes & Fisher, 2010). Mainly terrestrial, seldom climbs trees (European Commission, 2015). Usually lives for 3-4 years in the wild (GISD, 2015). Diurnal (Lutz, 2003). Is a vector for Leptospirosis and rabies (GISD, 2015). No natural predators (Csurhes & Fisher, 2010).
Females are sexually mature at 10 months, males at 4 months (Lutz, 2003). Breeds 2-3 times per year. Generally, 3 young per litter (GISD, 2015). Gestation 42-50 days (GISD, 2015). Young weaned at 5 weeks (GISD, 2015).
Pathway and vector description
Originally introduced to control rodents in sugar cane crops. The opportunistic Herpestes javanicus readily established and began to predate a wide range of other available wildlife. The only realistic pathway into Europe is by means of human intervention, mainly the pet trade (European Commission, 2015).
Mechanism of impact
Predation, Disease transmission
There is currently an EU wide ban on the sale of this species and personal and zoo ownership is being phased out (European Commission, 2017).
Has proved difficult to eradicate with few successes (Roy et al., 2002).
Readily trapped. This method is labour intensive and requires an ongoing commitment as the area is recolonised very quickly after trapping ceases (Roy et al., 2003).
Poison can be used but methods need to be improved to avoid killing non-target species (Roy et al., 2003).
Occupies a diverse range but prefers arid or semi-arid habitats. Can be found in woodland, agricultural areas, riparian zones, wetlands, deserts, coastal areas, landfill and urban areas (GISD, 2015).
Temperate Asia, Tropical Asia
In the EU it is currently naturalised in Croatia but nowhere else. It has been introduced to many tropical islands, islands in the Adriatic and to South America (GISD, 2015).
Afghanistan, Bangladesh, Cambodia, China, India, Iran, Iraq, Lao People's Democratic Republic, Malaysia, Myanmar, Nepal, Pakistan, Singapore, Thailand, Vietnam (GISD, 2015).

It is regarded as a pest in much of its introduced range and it is listed as one of the '100 worst' invaders by the IUCN.
The Irish climate is currently likely to be unsuitable for establishment of this species (European Commission, 2015).
