Life cycle (stages)
• Eggs are laid in dark humid animal burrows, cracks or crevices, or under dead leaves
• There are 4 larval instars, the larval stage lasting a total of 4-6 weeks
• The pupa requires 10 days for development • LC requires 40-50 days• Only adult females suck blood • Adult life span 2-3 weeks, 30-50 eggs/female.
