Question 1

Why do stink bugs invade homes in Indiana?

Accepted Answer

The brown marmorated stink bug (Halyomorpha halys) is an invasive species from Asia first detected in the US in the 1990s. It overwinters as an adult by aggregating in warm, sheltered spaces — your attic, wall voids, and sunny exterior walls are ideal. As temperatures drop in September–October, stink bugs seek entry points in masses. A home can host hundreds to thousands if untreated. The 'stink' is a defense chemical they release when crushed or disturbed — avoid vacuuming them without a bag, as the odor can linger.

Question 2

When should I treat for stink bugs?

Accepted Answer

Timing is critical. The most effective stink bug treatment is a preventive exterior perimeter application in late September, BEFORE the bugs aggregate on the structure and begin entering. Once stink bugs are already inside the walls and attic, treatment is more difficult. Leadtech Pest Services recommends scheduling your fall exterior treatment in August or early September for maximum effectiveness.

Question 3

Are stink bugs harmful to my home or family?

Accepted Answer

Stink bugs do not bite, sting, transmit disease, or damage the structure of your home. Their primary nuisance is the strong odor they release when crushed or disturbed, which can be difficult to remove from fabrics and surfaces. In large aggregations, they are deeply unpleasant. They can also stain surfaces with secretions. Their presence is primarily a quality-of-life issue rather than a health or safety risk.

Question 4

Can I seal my home to prevent stink bugs?

Accepted Answer

Exclusion is the most permanent long-term solution — sealing gaps around windows, doors, utility penetrations, soffits, and attic vents. However, stink bugs can find very small entry points and exclusion alone is rarely sufficient for heavily infested properties. The combination of a fall exterior perimeter treatment plus exclusion provides the best protection. Leadtech Pest Services identifies the key entry points during the inspection.

Question 5

How does Leadtech treat for stink bugs?

Accepted Answer

Leadtech applies an exterior perimeter treatment targeting the foundation, siding, window frames, soffits, and other aggregation sites. The treatment creates a residual barrier that kills stink bugs on contact as they attempt to enter. For interior populations already inside the home, targeted interior applications may be used. Backed by the Leadtech Guarantee — if stink bugs return between visits, we re-treat.
