Beyond the Stench: Unveiling the Life Cycle and Habits of Stink Bugs
Stink bugs were given their name for the odor they emit when threatened or crushed as a defense mechanism. These bugs are notorious, persistent and can invade homes in large quantities, not unlike boxelder bugs. They can be a significant inconvenience in terms of comfort and can potentially cause damage to plants, both ornamental and in the wild. Understanding the nature and life cycle of stink bugs is essential for finding an effective solution to your pest control problem, and preventing them from reemerging in the future.
Stink bugs, like Joro spiders, are recognized by their distinctive markings and are more or less an invasive species that is originally from Asia. Many experts would say they are physically identified by their "shield-esque" body shape, and since their accidental introduction in the 1990s, these insects have rapidly spread across the United States.
The life cycle of stink bugs is made up of three main stages, but go through several sub-stages of development as they progress through these individual eras of their lifespan, and each is observed to have a variety of unique characteristics and behaviors. These "between" stages are identified as occurring between the egg, nymph, and adult stages, and are commonly referred to as "instars" - each with varying and self-contained and age-defining traits.
During the egg stage, female stink bugs lay their eggs in clusters beneath leaves and other protected locations, and typically arrange them in two rows that are parallel to each other. These eggs, usually light green or white, hatch within a week, although hatching times may vary depending on differing environmental circumstances and can happen several days early.
Once hatched, stink bug larvae enter the nymph stage, progressing through five other developmental phases before reaching adulthood. Nymphs are smaller than adults and lack fully developed wings, gradually undergoing several color changes - beginning with hues of yellow or red and darkening as they advance towards maturity. Nymphs sustain themselves by feeding on plant juices, posing a significant threat to crops and ornamental plants.
Upon reaching adulthood, stink bugs measure approximately 1/2 inch to 3/4 inch in length and are easily identifiable by their brown coloration and distinctive shape. Unlike nymphs, adults have fully developed wings that enable them to fly for short periods over a small distance. They are mostly active during the spring and fall months but seek shelter indoors during the winter and, like rodents and boxelder bugs alike, often enter homes in search of warmth and protection from the cold.
Habits and Behaviors
Stink bugs are primarily herbivorous, feeding on a wide variety of plants and fruits, vegetables, and ornamental plants. They use their piercing-sucking mouthparts to extract plant juices, causing stippling, discoloration, and deformation of plant tissues. In agricultural settings, stink bug infestations can lead to significant crop losses.
Stink bugs are highly active outdoors in the summer months. They're attracted to light and groupings may appear around windows and doors. As temperatures drop in late summer and fall, stink bugs seek refuge in homes and other structures to ride out the cold. They enter through cracks, doors, and other openings and often form large groups in attics, within walls, and other hard-to-reach spaces in your house's infrastructure.
Managing Stink Bug Infestations
Preventative measures and managing stink bug infestations require a dynamic approach to problem solving. Here are only a few effective strategies from the multiple avenues you might take:
- Shut Them Out: Cover all points of entry, including (but not limited to) cracks around molding and windows, doors and siding. Use steel wool or silicone to fill gaps, along with caulk to ensure there aren't any smaller gaps that they could sneak through. Repair or replace damaged screens on windows and vents, or potentially any utility piping.
- Manage the Landscape and Weed Them Out: Consider planting stink bug-resistant varieties of plants and removing any close to the home's foundation. Trim back branches and shrubs around the property that touch the house.
- Indoor Control: Vacuum them up or use a family-and-pet-friendly spray to remove stink bugs from indoor spaces. Empty the vacuum bag or container outdoors or in an enclosed and sequestered area like a garage immediately to prevent odors or any stray bugs. Sticky traps and light traps can also help capture stink bugs.
