Morgan’s Repellent: Maximizing Performance & Troubleshooting Guide

The Golden Rule: Understanding “Vapor Density” Unlike drugstore sprays that coat a surface, or pouches that scent a corner, Morgan’s Repellent works by creating a Vapor Barrier. The essential oils infused in our pumice stones are heavier than air. They evaporate, sink, and fill the volume of the room from the bottom up. To get the results you paid for, you must place the jar correctly to allow this “sinking” action to occur.

1. Placement Strategy: The “High-to-Low” Method

The #1 reason for failure is placing the jar on the floor.

The Problem: If you place the jar on the floor, the heavy vapor has nowhere to sink and covers only a few inches of ground. The Solution: Place Morgan’s high up so the vapor can cascade down and fill the area.

• For Vehicles/RVs: Place the jar on the dashboard, center console, or hang it from the rearview mirror. Do not place it under the seat or on the floor mats.
• For Garages/Sheds: Place on a shelf, workbench, or window sill.
• For Boat Covers: Suspend the jar near the highest point of the canvas support.

Pro Tip: In a standard 1-car garage, one jar placed 5 feet high provides significantly better coverage than two jars placed on the floor.

2. Troubleshooting: “I Can’t Smell It Anymore”

Is it empty, or do you have ‘Nose Blindness’?

The Problem: After a few days, humans often develop “olfactory fatigue” (nose blindness) to the peppermint scent. You might think it has stopped working, even though the vapor density is still high enough to repel rodents (who have a sense of smell 50x stronger than yours). The Fix:

1. The Shake Test: Every 30 days, simply shake the jar. This rotates the pumice stones, exposing fresh, oil-saturated surfaces to the air.
2. Visual Check: As long as the stones look “wet” or dark, they are still releasing vapor. If they look bone-dry and white (usually after 90+ days), it is time to replace.
3. Increase: Increase Morgan’s Repellent with another 2.5 ounce jar to address excessive air flow or air exchange.

3. Troubleshooting: Active Infestations

Why am I still seeing droppings?

The Reality: No scent repellent on earth works like a brick wall against a starving mouse that has already built a nest. If they are already inside, they will tolerate the smell to protect their babies. The Protocol:

1. Clean First: Remove all food sources (pet food, bird seed) and clean up existing droppings. You must break their scent trail.
2. Evict: Use traps to remove the current residents.
3. Repel: Once the area is clear, place Morgan’s Repellent to prevent re-entry. Morgan’s is the “Security Guard,” not the “Eviction Team.”

4. Troubleshooting: “The Scent is Too Strong”

Managing Industrial Strength in Living Areas

The Problem: Morgan’s is formulated for industrial/storage use. In small pantries or bedrooms, the concentration can be overwhelming. The Fix:

First 24 to 36 hours: There is a stronger scent the first 24 to 48 hours, the reason is that the outer layers of oils on the stones are rapidly evaporating.  This is good in it creates an area much quicker that stress the rodent in a much shorter amount of time.

Regulate the Venting: You do not need to take the lid completely off. Punch 4–5 holes in the foil seal, or leave the lid slightly unscrewed but still on. This slows the release rate, makes the jar last longer, and keeps the scent manageable in smaller spaces.

Place Fewer Jars: If the scent is too strong and multiple jars are being placed place a lid on one of the jars to use later.

5. Troubleshooting: Drafty/Open Areas

Why it fails in barns or carports.

The Problem: Wind and heavy airflow strip the vapor barrier away before it can build up to a repellent level. The Fix:

Morgan’s works best in enclosed or semi-enclosed spaces.

• If using in a barn, place the jar directly inside the engine bay of the tractor or in the tack room, rather than in the open aisle.
• If using in a carport, place the jar inside the vehicle cabin or trunk.

Quick Reference: How Many Jars Do I Need?

• Compact Car / Truck Cab: 1 Jar
• RV / Camper (Winterizing): 2–3 Jars (One front, one middle, one rear bedroom)
• 1-Car Garage / Shed (Enclosed): 1–2 Jars
• Large Barn / Warehouse: Place 1 jar every 400 square feet (focusing on corners and entry points).
• Closed Tight Areas: Tractor & Combine Cabs, Sea Containers, Campers and Covered Boats, Closed Stored Vehicles, Shrink Wrapped Boats, Engine Rooms; 2.5 ounce will provide scent for as much as an area 20′ x 20′ x 8′ or 3,200 cubic feet, as tested.
• Semi Tight Areas Where Air Exchange Occurs: Attics, Homes, Seasonal Cabins, Feed & Hay Storage, Under Sheds, Sheds, Cars  & Tractor Engines, Rental Storage Areas, Pump Houses, Tack Rooms, Chicken Coops, Greenhouses, Utility Boxes, Basements, Drop Ceilings, Crawlspaces: 2.5 ounce will provide scent for as much as 15′ x 15′ x 8′ or 1,800 cubic feet.

Usage Warning for Sealed Spaces

Because there is minimum air exchange, the vapor concentration will become extremely high.

Vent the Lid: Do not remove the lid completely. Just punch 2-4 holes in the foil seal or unscrew the lid slightly. If you open it fully in a sealed Sea Container, the scent will be overpowering when you finally open the doors.

Airing Out: When you re-enter spaces (e.g. opening the Tractor or Combine Cab for Use), place the lid back on the jar to save for later use, open the door and let it air out for 15 to 30 minutes before sitting inside.
