We’re excited to officially launch Rodents Away Odor Free Expandable Straw Foam—a powerful new addition designed to help you finish the job after mice activity has been addressed.

If you’ve ever wondered what to do after mice have left, this product is the missing piece. Repel mice first, then seal and protect the small openings they used to get inside in the first place.

Why We Launched Expandable Straw Foam

Mice don’t need much space to get indoors—gaps around pipes, wiring, vents, sill plates, and cracks in foundations are all easy access points. While repelling mice is step one, long-term prevention depends on sealing those openings.

Expandable Straw Foam is designed to:

• Fill, seal, and insulate small openings
• Create a durable physical barrier
• Help prevent mice and insects from re-entering
• Be suitable for both indoor and outdoor use

It’s a proactive solution that works after mice have vacated, helping protect your space moving forward.

How Expandable Straw Foam Works

Expandable Straw Foam expands after application to fill gaps and cracks where air, moisture, and pests can enter. Once cured, it forms a solid barrier that can be trimmed, sanded, painted, or stained for a clean finish.

Key product highlights:

• 340 g (12 oz.) can expands up to 3× once deployed
• Industrial-strength durability
• Straw applicator for precision in tight spaces
• Approved for interior and exterior use
• Effective in temperatures as low as -18°C (0.4°F)

Where to Use Expandable Straw Foam

Use Expandable Straw Foam anywhere small openings need to be sealed—especially areas where mice or insects may enter:

• Homes, cabins, and offices
• Garages, sheds, and barns
• Warehouses, trailers, and RVs
• Around pipes, wiring, vents, and utility penetrations
• Interior and exterior cracks and gaps

How to Use Expandable Straw Foam (Step-by-Step)

• Be Prepared: Wear protective clothing, gloves, and goggles. Use with adequate ventilation. Keep a cloth and acetone (nail polish remover) nearby for cleanup while foam is uncured.
• Clean the Area: Remove oil, grease, and dust. Mask nearby surfaces with tape or plastic if needed.
• Lightly Mist With Water: Lightly mist or wipe the area with water before application.
• Shake Vigorously: Shake the can vigorously for 1 full minute.
• Attach the Applicator: Screw the straw applicator onto the valve stem.
• Apply Correctly (Important): Always use the can upside down. Point the straw to the far end of the cavity. Fill the opening approximately 30% only to allow for expansion.
• Dry & Cure: Dries to the touch in about 10 minutes. Fully cures in 12–24 hours. Do not disturb foam while curing. After curing, excess foam can be trimmed with a knife or removed with sandpaper.
• Protect From Sunlight (Exterior Use): If the foam will be exposed to direct sunlight, paint or stain it after curing.

The Best Results Come From a Two-Step Approach

For maximum effectiveness, we recommend a repel first, seal second strategy:

• Use Rodents Away Odor Free sachets to encourage mice to leave the space
• Apply Expandable Straw Foam to seal entry points and prevent future access

This approach helps address current activity and reduces the chance of repeat issues.
