Several species of weevils are known to enter structures, primarily in the fall and overwinter. Other species enter at the beginning of spring when outdoor conditions become unfavorable. Weevils are small beetles that can become a significant nuisance when they find their way into homes. These pests are typically found in gardens, where they feed on a wide variety of plants, including ornamental flowers, fruits, and vegetables.

Since larva are subterranean, they are rarely ever seen. Adults are typically nocturnal and remain hidden on plants or in litter or the soil during the day. Overwintering adults emerge from early May to late July. After a few weeks, the females will start laying eggs near the crown of the host plant. Between 500 – 1,600 eggs will be laid. In just 2-3 weeks the eggs hatch and larvae burrow into the soil and start feeding on the roots. Many of these weevils are flightless and  parthenogenetic ( reproduction without male).
