Larder beetles overwinter as adults in protected places, including in walls and spaces and gaps they find around the outside of buildings.
Throughout the summer months, female Larder beetles will lay over 100 eggs in food sources they find for their larvae.
The eggs take about 2 weeks to hatch.
Larvae will feed for 40-50 days; molting up to five times if male, six if female, before pupating.
The pupal stage lasts from 3-7 days depending on temperature and moisture conditions
The total larder beetle life cycle takes about two months.
