Retrofit Weep Hole Cover™ Pest Exclusion Device - US Patent # 6,474,031, US Trademark #3,506,756

For existing (retrofit) construction

Weep holes on masonry wall construction, while necessary to vent moisture, are an open door to a home or building for pests. Once inside they can chew on wires, eat food and spread disease like Salmonella or Lyme Disease. Slam it shut with the Tamlyn Retrofit Weep Hole Cover™!!

DESIGN FEATURES: Provides efficient management of moisture andair flow, preventing damage caused by freeze / thaw cycles and is the first step in stopping conditions that allow mold to develop, ensuring optimum performance of the walls. Unique patented-shaped design material permits air and water to move through the material.

Fundamental in helping achieve Green Building goal of healthy indoor air quality. Per products that reduce or eliminate pesticide treatments are considered green. Periodic pesticide treatment can be a significant health and environmental hazard.

Naturally excludes unwanted, allergen and disease-carrying elements from the house without pesticides (most common method for roaches, rodents, snakes, spiders, scorpions and lizards etc. to enter the home is through weep holes).  Physical pest barrier very effectively denies access. Application on exterior of home/building minimizes the use of pest control materials indoors. Accepted by US Environmental Protection Agency Energy Star® program in helping achieve better indoor air quality (keeps rodents etc. from entering through the weep holes, dying inside the walls, and releasing odors).

Why the Tamlyn Retrofit Weep Hole Cover is better than copper mesh:

- mesh like any filter (such as your car air filter) will eventually clog with debris, shutting down necessary ventilation through the weep hole, and needing to be replaced 

- as the mesh is stuffed into the back of the weep hole, you can’t see when it gets clogged and needs replacing, which could lead to mold development in the walls as moisture levels build up 

- the Tamlyn Retrofit Weep Hole Cover is a visible exclusionary barrier to pest entry and you can easily see when it needs to be removed and cleaned or replaced

Subject: Feedback via the Tamlyn Info Request

I just wanted to thank you for inventing and selling the retrofit weep hole covers. What an excellent product! I wanted to share my story with you.

One of the reasons we moved from our previous 35+ year old house was it had serious rodent issues. We lost many nights sleep listening to rodents inside our walls and in our attic. It was horrifying, depressing and embarrasing, especially with overnight visitors. Eventualy, we moved into a brand new house in an upscale subdivision but guess what? RODENTS HAD MOVED IN FIRST!

I began researching and learned how rodents can access a home via weep holes. Yesterday afternoon, I inserted a cover into each weep hole and by bed time, the house was DEAD SILENT. In fact, the silence was deafening as we are used to LOUD hearing gnawing, thumping and scratching through the night. It appears the rodents were out when I installed the covers and couldn\'t get back in afterwards. IT WAS TRULY WONDERFUL TO NOT BE AWAKENED BY CONSTANT GNAWING.

Knowing what I know now, I will be recommending this product to all my neighbors and friends who aren\'t too embarrassed to admit they have a rodent problem.

Thanks again for making such a wonderful, affordable product available. It has already dramatically increased our quality of life and enjoyment of our new home.



Let Those Unwanted Critters Weep, Not You

Weep holes are both positive and negative — they provide ventilation and a welcome mat to mice and more. While necessary for construction, they then become an open door to unwanted animals and pests.... Click here for more
