In practice

What the first
few days look like.

Written from the product's own application instructions. A barrier treatment works best applied at entry points, not just on the bugs you see.

FIRST SPRAY · TARGET ENTRY POINTS

You spray the entry points

Focus on doors, windows and gaps where stink bugs are likely to appear.

ON CONTACT · IT WORKS

Stink bugs are targeted directly

The formula targets stink bugs on contact and starts building the defensive barrier.

FIRST WEEK · BARRIER HOLDS

Activity around entry points drops

The well-balanced blend forms a durable barrier that limits future activity.

ONGOING · MAINTAIN IT

You reapply as needed

Reapplication is what keeps the barrier durable through the season.

The comparison

Next to a typical
stink bug spray.

The difference is the barrier: lasting protection at entry points, not just a one-time knockdown.
