Immediately after hatching, the larvae begin to feed. Therefore, the adult lays eggs where the larvae can feed quickly and easily. Most of the time, the female lays her eggs on dead insects. However, larvae can feed on both animal matter (like fur and hair) and vegetable matter. This insect commonly infests hornet’s nests and those of several species of birds. The adult flies and is drawn to light, so it is often found on window ledges. The adult insect will have to go outside to feed on the nectar and pollen of flowers. Afterwards, the female may re-enter the house to lay her eggs.
