Fall Invaders in Osage Beach & Camdenton: Lady Asian Beetles & Boxelder Bugs—How to Keep Them Out

Why fall = “bugs on the siding”
Warm afternoon sun plus cool evenings trigger swarming on south/west walls. From there, pests slip into tiny gaps to overwinter in attics and wall voids.

Quick ID Guide

Asian lady beetles vs. native ladybugs

• Asian lady beetle: orange–red, spots vary; often a black “M/W” behind the head; clusters in large numbers.

• Native ladybug: smaller, bright red with even spots; rarely swarms structures.

Boxelder bugs

• Boxelder bug: black with red/orange lines on wings; gathers on maples/boxelder trees and sunny siding; enters buildings in fall.

Common Entry Points on Lake Homes

Where they squeeze through

• Upper siding/soffit seams, fascia & rake boards

• Attic/ridge vents (coarse screens)

• Gaps at utility lines, cable/AC penetrations, meter boxes

• Window/door casings, weep holes, foundation/top-plate gaps

Prevention That Works (do this before the first cold snap)

Exclusion + targeted exterior protection

• Seal with high-quality caulk/foam at trim, utility holes, and siding transitions.

• Add fine mesh to attic/soffit vents; repair screens & weather-stripping.

• Reduce exterior night lighting or swap to warmer color temps.

• Schedule a perimeter/upper-story treatment on sun-exposed walls to intercept migrants.

Why DIY Sprays Disappoint

Timing and placement beat blanket spraying
Lower-wall sprays miss attic/soffit seams and can stain siding. Correct products and upper-elevation application are key.
