Rid-O-Mice Stainless Steel Weep Hole Covers protect against mice and other pests from entering homes via weep holes. 
Read our answers to the most frequently asked questions concerning weep holes and Rid-O-Mice.

Weep Holes are gaps in the brick along your homes foundation and above windows and garage doors. 

Weep Hole Covers are inserted into weep holes for the purpose of blocking mice, lizards, snakes, wasps, bees, scorpions and large insects. They achieve this while at the same time protecting the walls ventilation. Watch out for solutions that do not protect ventilation.

(If you have a contemporary brick home from the past 30 years - likely YES)

This depends on the building specs of your home. Typically modern style brick facade homes require weep holes as noted in most building codes across North America.

Contemporary wall construction uses an air gap between the inner wall structure and the exterior brick. The inner wall structure uses vapor barrier to stop the passing of moisture through the wall. In older homes moisture would pass right through. both from the inside out and outside in. 

With vapor barriers and wall gaps moisture builds up in the inner wall and without escape can introduce mold and rot to the structure also inviting infestations.

Mice collapse their entire bodies down to the size of their nose. They use their legs to push through the weep hole.

Trash mortar is nuissance mortar that causes rough sides inside your weep hole. It exists when brick layers don't take care to avoid mortar from entering the hole during the laying process. It can impede airflow and make it hard to insert covers. Depending on severity it can require drilling it out with a mason drill bit.

Rid-O-Mice comes with a 10 year prorated warranty and the covers have been in homes around the world for over 12 years. The expected life is 20 plus years. Providing they are not sitting in constant dirt, water and salt they should only discolor while maintaining their structure.

That is a great question. In reality homes are not built with pests in mind. To do so would be added cost in material, time and labor. While weep hole ventilation is mandated in the building codes, damage from ivading pests is not considered. All this to say its in your hands.

Yes. Using regular garden shears (the hand held type) you can easily trim the units to the size you require. Wear gloves and eye protection as you are cutting metal and cut ends can be sharp.

Ensure your tools are clean and dry.

Sun by itself does not impact the covers. We have noticed the covers will slightly discolor over time due to all the elements upon it.

You can paint Rid-O-Mice with proper paint used for stainless steel. Make sure you consult your paint manufacturer and follow their guidance.

Existing sod must first be removed. Next, a base is created using a special blend of crushed rock (2" – 4" depth), then smoothed and compacted. The artificial grass is then rolled onto the surface of the base and seamed together if necessary (turf widths are 15′.) Then the infill material is is spread over the top of the grass using a fertilizer spreader and brushed to the bottom of the artificial grass. The grass product type and the type of use determines the type and amount of infill. The infill can be sand, rubber crumb, or a combination of the above. Installation for synthetic putting greens is similar but there are additional layers of base materials that need to be thoroughly compacted. Refer to our installation overview for more information.

Standard brick is 2.25 inches or 2.75 inches tall. We see more 2.75 inch weep holes by far. However with newer brick and stone finish some weep holes are 3 and even 4 inches tall. 

Weep hole widths can vary greatly along the same wall due to the nature of the brick laying process and the brick layer. Mice can get in holes as small as 1/4 inch wide and some weep holes can be less than that width ranging up to over an inch wide. Rid-O-Mice can be used in holes ranging from 5/16ths inches wide to 1 inch wide. If wider than 1 inch you may consider a bonding agent to hold Rid-O-Mice in place as the spring will no longer be effective at that width.

These are intended to fit tight in the hole so the spring in the covers wings grips the weep hole walls and cannot be pulled out by mice. 

Strongly ill advised, impedes air pressure to do its job allowing inner wall cavity to breath and expell moisture. Clogs with debris over time, invites mold, rot and pest infestation.
