Social, agricultural and environmental impacts of the Singapore ant
This ant is a significant household pest in some places. It is known to infest houses, attack and bite people in bed and get into food products.
The Singapore ant can cause extensive economic damage, for example, it chews holes though fabric and rubber goods, removes rubber insulation from electric cables and phone lines, damages polyethylene cable, and shorts out car ignitions in vehicles parked in infested areas over night.
The ant may also carry human diseases.
It displaces other ant and invertebrate animals where it occurs.
