Mexican free-tailed bats

Check out a video of the Mexican Free-Tailed Bat:

Fun bat facts:

mexican free-tailed batThese bats are insectivores, dining and devouring on a large number of insects including🐞 corn earworm moths.  Bats 🦇 save farmers millions on pesticides. 👍🏼 Bats are a natural pesticide!

This makes them a definite economic asset to farming communities.

Did you know? Bats usually collect together in the same room to sleep. These bats do!  They have a range of complex social behaviors. They use scent marking and vocalizations to communicate with each other. 🦇🦇 They use a different set of sounds for echolocation to navigate and find food. Very Interesting!

Another fun fact – Bats involved in a war? Did you know?

“Free-tailed bats have supported several American war efforts as well. When Confederacy ports were blockaded in the latter part of 1863, a gun powder factory was established near San Antonio. The powder’s most valuable ingredient, saltpeter, was made from local bat guano. During World War 11, major free-tailed bat caves near San Antonio were carefully guarded during top-secret research coded “Project X-Ray.”* The U.S. Air Force hoped to use bats as carriers of small incendiary bombs that would be dropped on Japan. The project began to lose favor when escaped bat bombardiers set fire to air base barracks and a general’s car. After being passed on to the Navy, and finally the Marine Corps, the project was canceled.” –

Townsend’s Big-eared Bat

Townsend are a bat of “special concern” as stated by Fish & Game – in the state of California.

Nationalparks.Gov states “today the Townsend’s Big-eared Bat, is state-listed as an Endangered species in Washington, a Sensitive species in Oregon, and as a Species of Special Concern in Texas, Montana, and California, and they are on the Blue List in British Columbia.”

Check out this beautiful colony we came across.

We were asked to remove this colony by the owners of the building. We are working closely with other conservationists to make sure nothing happens to this colony. They are vital and we love these amazing bats!

Did you know?

Fun facts • this bat curls up its ears so they look like ram’s 🐏 horns when roosting Or hibernating. 🦇 When flying they extend or contract their ears.

• These bats do not tuck themselves into cracks/crevices like many bats do, but prefer open roosting areas in large rooms.

• These mammals are sensitive to disturbances. Light and movements can cause them to awake and their ears will move as they try to identify the intruder. If the disturbance is more than a few seconds, the entire group takes flight and the roost may be abandoned. 😢

Pallid Bat

pallid batBay facts: Pallid bats are amazing! Their ears are long and they are able to hear👂🏻 the soon to be food walking 👣along🦂🐛🐜🕷🦎They are insectivores that feed on arthropods such as crickets and are capable of consuming up to half their weight in insect every night. 👅They leave much evidence of the breakfast with bits pieces of the insect parts ☠️ on the ground in the morning. Pallids are know to be one of the stinkiest bats!! #bats #westernbatspecialists #batland #batfactsforever

Mind your manners! The pallid bat is an impressively tenacious bat, thanks in no small part to its penchant for…

Posted by Bat Conservation International on Wednesday, November 14, 2018

Pallid bats are gregarious and will roost in colonies between 20 and several hundred individuals. They love to typically roost in rock crevices, but they can also be found in attics, barns, caves and under bridges. These are extremely stinky bats! The pallid bat will night-roost by locating a place that is warm from the latent heat of the day and eat prey caught while flying or swap social information with other members in the colony.

Females will form maternity colonies. These colonies are typically small, with populations around 20 or so individuals. Each mother will give birth to one pup in May or June and the pup will stay with the mother until it can fly—usually within five to six weeks. 🦇 Pallids – bats are maternal. 🦇 Female Pallid bats do not raise newborns of other females. Some colonies will care for each other young….. but NOT pallids They only care for their own. <<<<<<<<<<<<<<<<<<<<<<<<<

Bat Guano & Urine Damages

Aside from an extremely unpleasant odor, bat guano and urine cause damage to structures aesthetically, chemically, and structurally.


Chemical Effect

Guano and urine have a chemical effect on building materials. Both substances contain high levels of uric and other acids. These acids can attack the calcium carbonate and other ‘binders’ in natural stone, artificial stone, and even concrete. They can corrode metal building materials such as copper or bronze and attack their protective patina. This can result in problems, both aesthetically and structurally!



Although brick and other clay-based materials may be relatively resistant to acids, they are vulnerable to damage from salts. Guano contains high levels of phosphates, ammonium, potassium, chlorides, and other materials. These and the salts resulting from acid corrosion can result in severe problems of efflorescence* and breaking. Similarly, the effect of the acids and salts on the porosity of masonry and other materials can result in accelerated moisture and frost damage. The acid can also serve as a catalyst in the process of oxidation on nails, screws, and metal flashing’s around the structure.

bat urine

Bat urine

Bat urine readily crystallizes at room temperature. In warm conditions under roofs exposed to sun and on chimney walls, the urine evaporates so quickly that it crystallizes in great accumulations. Boards and beams saturated with urine acquire a whitish powder-like coating. With large numbers of bats, thick and hard stalactites and stalagmites of crystallized bat urine are occasionally formed.


Fabrics & Insulation

Materials such as fabrics and insulation are extremely porous and susceptible to deterioration, thus leaving removal and replacement as the only viable solution for eliminating the guano and urine.

As already mentioned, bat guano and urine have a high concentration of uric and other acids, meaning that the guano and urine are extremely corrosive. This is especially true when there is repeated contact with surfaces such as metals and wood. Over a long period of time urine may cause wood deterioration. As the urine saturates the surfaces of dry wood beams and crystallizes, the wood fibers expand and separate. This can be quite severe, ultimately resulting in the need to replace such materials.



Long-term exposure to bat urine can be problematic, particularly for softer stones like marble and travertine. These materials have a higher percentage of calcium carbonate that makes them more vulnerable to acidic compounds (like guano and urine). These acids attack the calcium carbonate and other ‘binders’ in natural stone, artificial stone, and even concrete. Granite and other hard surfaces can also be damaged, depending on the porosity and permeability of the material (granite’s that are lighter in color tend to be more absorbent). While the outside surface of granite is typically sealed after installation, the back and undersides of the material are left untreated and are vulnerable to damage (please note: even when sealed, granite may still be absorbent).

*efflorescence. A whitish, powdery deposit on the surface of rocks or soil in dry regions. It is formed as mineral-rich water rises to the surface through capillary action and then evaporates. Efflorescence usually consists of gypsum, salt, or calcite.

Holy Shirt Batman we are Famous!

We get t-shirts made from and they have bats_headerchanged the way t-shirts are done. They make it “uber” easy to get our custom shirts prints.

Not only did they get us our beautiful shirts but they were so kind to write a blog post about us!  Our Project planner and CFO Rebekah Wright and our Website Director Chelsea was able to provide Uberprints with Additional information on what we do as a company.
