What happens before the bats are removed from your structure.


Bat ExclusionBat Exclusion is a technique where all potential bat entry points stated in your inspection report and/or service agreement/contract/proposal, are made uninhabitable or impervious to a bat by the use/application/installation of exclusion materials by Your Bat Professional.


Bat Exclusion materials are building materials or components that may be used/applied/installed/dispensed, but are not limited to, are caulk, adhesives, or sealants, backer rod, chinking, foam, wire mesh, metal flashing or coil stock, chimney caps, or any other building construction materials that will prevent the colony of bats from relocating in / on your structure once the bat eviction/venting devices have been installed on/over the current entry points on your structure.


Bat Exclusion materials must have a minimum service life of one year or a service life that is equal to or greater than the warranty provided in the inspection report and/or service agreement/contract/proposal provided to you by Your Bat Professional.


Bat Exclusion materials shall be applied to all potential bat entry points that lead into the interior of your structure from the exterior of your structure.  Bat entry points are defined as areas eighteen (18) inches above grade that may emit air draft from your structure that are greater than or equal to 5/8 inch round or 3/8-inch wide and ¾ -inch long regardless of its orientation. Bat entry points in use should not be closed until all volant (flightless) bats have been evicted/vented from your structure.  


Cure Period is the time that it takes an uncured material, such as foam, chinking, caulk, adhesive, or sealant, to fully dry or solidify once it has been exposed or dispensed into a gap/opening/space between two surfaces. Cure periods vary among foams, caulks, adhesives, and sealants.  Cure periods of these products are also subject to temperature, humidity, and volume.  Therefore, Your Bat Professional must refer to the manufacturer’s technical data, label, or directions to determine the cure period prior to use on your structure.


Caulking or Sealing may be referred to as the process of dispensing/applying/injecting an uncured material from a tube, with the aid of a caulking gun, into a gap/opening/space between two surfaces for the purpose of making it uninhabitable or impervious to bats.  Gaps/openings/spaces equal to or greater than a ½ inch should have rigid backing material installed in the gap/opening/space prior to caulking or sealing.


Backer RodBacking Materials, such as but not limited to backer rod, wire mesh, or non-woven fibers, are rigid materials that may be installed in gaps/openings/spaces equal to or greater than a ½ of an inch.  These materials will prevent bats from being exposed to uncured materials, hold sealant materials in place while curing, and will reduce volume of curable materials necessary to seal gaps/openings/spaces.  Backing materials will allow application of sealants to manufacturer’s recommendations and can decrease the curing period for some sealants.


Dispensed foam products shall be used as a backing material only. Any dispensed foam that requires a cure period of more than four (4) hours shall not be applied within a two foot radius of any active bat entry point on your structure by Your Bat Professional four (4) hours prior to sundown.  


Caulks, Sealants, and Adhesives are uncured materials that may be package in a tube and dispensed/applied/injected, with the aid of a caulking gun, into a gap/opening/space between two surfaces.  This process is referred to as “caulking or sealing” bat entry points for the purpose of making them uninhabitable or impervious to bats.  Gaps/openings/spaces equal to or greater than a ½-inch should have rigid backing material installed in the gap/opening/space prior to the caulking or sealing process.  These materials come in a variety of formulations to accommodate any surface application.  Therefore, Your Bat Professional must refer to the manufacturer’s technical data, label, or directions to determine the product that best fits his application needs on your structure.

Caulk Gun

Foaming Materials are uncured materials that are packaged in an aerosol can and dispensed/applied/injected into a gap/opening/space between two surfaces and or may be used as a backing material for caulking and sealing.  This process is referred to as “foaming” bat entry points for the purpose of making them uninhabitable or impervious to bats.  Uncured foaming materials may endanger the welfare of the bat colony.  Any foaming material that requires a cure period of more than four (4) hours shall not be applied within a two foot radius of any active bat entry point on a structure four hours prior to sundown.  These materials come in a variety of formulations to accommodate any surface application.  Therefore, Your Bat Professional must refer to the manufacturer’s technical data, label, or directions to determine the product that best fits their application needs on your structure.

 

Chinking Materials are uncured materials that are packaged in one to five gallon containers and applied, with the aid of a chinking tool, into a gap/opening/space between two logs.  Chinking is a flexible, elastomeric material with the appearance of concrete mortar.  This process is referred to as “chinking” bat entry points for the purpose of making them uninhabitable or impervious to bats.  Gaps/openings/spaces equal to or greater than a ½-inch should have rigid backing material installed in the gap/opening/space prior to chinking.  Any chinking material that requires a cure period of more than four (4) hours shall not be applied within a two foot radius of any active bat entry point on your structure four (4) hours prior to sundown.  Therefore, Your Bat Professional must refer to the manufacturer’s technical data, label, or directions to determine the cure period prior to use on your structure


Uncured materials may endanger the welfare of the bat colony.  Any material that requires a cure period of more than four (4) hours shall not be applied within a two foot radius of any active bat entry point on your structure four (4) hours prior to sundown.  Your Bat Professional shall also make an effort to re-inspect all potential entry points prior to an application of such materials in order to prevent bat exposure to the uncured materials.


Materials that require a cure period of more than four (4) hours that are applied after the placement of a rigid backing material in the gap/opening/space may be applied within the two foot radius of an active bat entry point at any time during daylight hours.

Fasteners

A Fastener is a building material, such as a screw, nail, or a staple, that requires a hand tool to fasten another material firmly in place, such as wire mesh, flashing, or plywood.  Adhesive tapes or tape-like materials shall not be used by Your Bat Professional as a fastener for bat exclusion or bat eviction/venting.


Metal Materials, such as flashing, coil stock, and sheet metal, are building materials that may be used as an exclusion material and shall be fastened to the structure.  These materials can be composed of stainless steel, galvanized steel, copper, or aluminum and shall not be less than .019 gauge.


Siding Materials, such as Wood, Vinyl, and Wood Composite Materials, are building materials that are used to protect a structure or that may be used by Your Bat Professional as a bat exclusion material.

 Chimney Cap

Chimney Cap is a device that is fastened to a chimney or chimney flue that will prevent bats from entering the flue.  Manufactured and custom chimney caps can be composed of stainless steel, galvanized steel, copper, or aluminum and shall not have an expanded metal mesh size that exceeds ¾ of an inch.  Placing screen, wire mesh, or expanded metal over or in the flue is not acceptable and is illegal in most states. Your Bat Professional is responsible for complying with all local, state and federal laws that pertain to chimney caps and chimneys.   


A Vent is a device that allows air to escape or enter your structure.  Round hat vents, square roof vents, gable vents, flap vents, and dryer vents may have forced air from a fan or blower.  Square roof vents, ridge vents, soffit vents, gable vents, and sewer vents may allow air to enter and escape your structure.


A Vent Cover is a device that covers an existing vent, it must be fastened to the vent or structure and will prevent bats from entering the vent.  Manufactured and custom vent covers can be composed of stainless steel, galvanized steel, copper, aluminum, or plastic and shall not have an expanded metal or mesh size greater than 0.375 of an inch.  Perforated vinyl siding, wire mesh, or expanded metal covering the vent is acceptable in most states with the exception of dryer vents. Vent covers placed on dryer vents may create a fire hazard, and extreme caution should be used by Your Bat Professional when excluding these type vents.  Non-woven fiber materials meeting the aforementioned tolerances may be placed inside of a ridge vent or any other entry point that vents air from your structure. Your Bat Professional is responsible for complying with all local, state and federal laws that pertain to covering or screening vents.   


Drip Edge is a material comprised of aluminum or other metal sheeting that may be fastened to span the gap between a fascia board and the roof sheathing around the perimeter of your structure.    


Wire Mesh and Screening is a material comprised of woven or welded metal strands to a specific sieve size not greater than 0.375 inch.    




How Your Bat Professional removes bats from your structure.

  

Bat Eviction/Venting is a process of removing bats from a residential or commercial property by the use of a one –way exit device that allows bats to leave the structure but not re-enter.


Baby BatTime of Year Concerns  

Your Bat Professional should consider both the time of year and the life cycle of bats within their respective geographic region prior to eviction venting.  Your Bat Professional should exercise caution between the months of April through August to ensure that non-volant, juvenile bats are not present in the structure.  Between the months of October through March, Your Bat Professional should exercise caution that a winter hibernaculum may exist in your structure and install eviction/venting devices during any exclusions performed at this time. In addition, eviction/venting devices should remain in place until such time that average night-time temperatures regularly exceed 50°F in your area or region.

  

Bat Cone

Valves:  Tubes, Cones, Mesh, and Chutes

Bat eviction/venting devices can be fabricated from metal, mesh, or rigid plastic materials that have a base opening greater than or equal to 3 square inches in area.  Exit opening of the device shall not exceed one square inch in area unless a flap of flexible material is attached to the exit opening.   Bat eviction/venting devices shall be installed at an angle greater than or equal to 30° below the horizontal plane or shall be outfitted with a flap of flexible material attached to the exit opening by Your Bat Professional.


Plastic Netting & Sheeting shall be constructed from a polymer that retains flexible and pliable properties above 50 degrees Fahrenheit.  Plastic netting shall be less than or equal to 0.375 inch mesh size.  Plastic sheeting shall be between 2 and 4 mil thickness.  Both materials shall be attached using an approved fastener.

  

Bat trapping is not a biologically sound method of eviction/venting and should not be used to mitigate a structural bat infestation.  In some cases, however, bat trapping may be ordered by a regulatory authority to address specific health concerns such as human rabies exposure or to perform scientific research.
