Hang-outs
Found naturally in every moist environment such as damp soils, lakes, ponds and slow moving rivers.
Danger
Skin irritation and allergic reactions to severe liver, neurological damage and animal deaths. Toxins are implicated in cancer.
Protection
Pay attention to public health advisories, do not swim or allow your pets to access water subject to high risk alerts, be aware of and do not enter water with ‘musty’ smells and surface scums, do not drink untreated water.
