Effective Snake Repellent for Venomous and Non-Venomous Snakes

Long-lasting formula disrupts sensory perception without harm, covering up to 1.4 hectares

Victor® Snake-A-Way® granular repellent is an effective solution for keeping away both venomous and non-venomous snakes. Its long-lasting formula temporarily disrupts the sensory perception of snakes without harming them, with a 91% effectiveness against rattlesnakes and garter snakes. It is EPA-registered and applied around the perimeter of areas to be protected, covering from 819 m² to 1.4 hectares. It contains naphthalene (7%) and sulfur (28%) and lasts 2 to 3 months after each application. Ideal for protecting homes, sheds, gardens, and more.

• Repels venomous and non-venomous snakes.
• Temporarily disrupts the sensory reception of snakes without causing harm.
• EPA-registered snake repellent.
• Long-lasting extended-release formula. Lasts 2 to 3 months after application.
• Apply around the perimeter of the area you want to protect.
• 91% effectiveness in repelling rattlesnakes and garter snakes.
• Contains Naphthalene (7%) and Sulfur (28%).
• Covers from 819 m² to 1.4 hectares.

Victor® Snake-A-Way® granular repellent has been tested by an external laboratory to be an effective repellent against both venomous and non-venomous snakes. It can be used to protect cabins, homes, sheds, trailers, garages, and flower beds from snake intrusion.

How Does Snake-A-Way® Work?

The Jacobson's organ is a special olfactory organ used by snakes that helps them detect environmental stimuli. In fact, the Jacobson's organ is a key survival tool for these reptiles. Victor® Snake-A-Way® snake repellent granules affect the Jacobson's organ, and snakes flee from the now-protected area in search of air free of the repellent.

Victor® Snake-A-Way® Snake Repellent Granular

Victor® Snake-A-Way® contains a unique formula that is third-party tested and effective against even the toughest snakes. This long-lasting snake repellent can be used to repel rattlesnakes and garter snakes from areas around houses, cabins, trailers, garages, flowerbeds, and more.

 

 

Sends Snakes Scurrying

Snake-A-Way®’s unique formula works to temporarily disrupt the snake’s Jacobson’s Organ (auxiliary olfactory sense organ), on which a snake relies for its survival. This successfully causes a snake to become disoriented, forcing it to retreat in search of fresh air.

Easy Application

Wearing gloves, spread Snake-A-Way® granules along the perimeter of the area you want to protect to create a long-lasting snake barrier. Once applied, the formula starts working, and lasts until the scent dissipates. To repel rattle snakes, sprinkle in bands 8-12 inches wide, and to repel garter snakes, sprinkle Snake-A-Way® in bands 4-5 inches wide.

 

 

EPA Registered Snake Repellent

Snake-A-Way® is EPA registered which means, when used as directed, it will not have adverse effects on humans or the environment.

Visible Alpha Tags (VI Alpha) x 100 u. ²⁵

$ 100.00 USD

This product is sold by BIOWEB Global in LATAM, but if you are in United States or Canada please contact the vendor Northwest Marine Technology directly.

The VI Alpha Tags are a small, fluorescent tags with an alphanumeric code designed to identify individual animals. VI Alpha Tags are implanted internally but remain externally visible for easy recovery. The new VI Alpha Tags were introduced in 2010.

VI Alpha Tags are available in two sizes: standard (1.2 mm x 2.7 mm), shown in yellow, and large (2 mm x 5 mm), shown in orange. The larger tags are easier to read than the standard tags, and are suitable for larger animals.

Large tags have black lettering on a fluorescent orange background, while standard tags are available with black lettering on a fluorescent orange, red, yellow or green background. Each color has 2,500 different codes. The codes available are the letter-number-number combinations from A00 through Z99 (excluding Q00-Q99).

Tag readability and detection can be enhanced by fluorescing the tags with the VI Light.

VI Alpha Tags are easy to load. Slide the tag into the needle, and snap it off.

Each 100 tags ordered must be the same color, and will have consecutive coding.

Please contact us for advice about applications to particular species.

• VI Alpha Tags are easiest to read when they are placed under clear or translucent tissue. In some cases, the tags can be placed under pigmented tissue where they are not visible in ambient light, but can be seen when they are fluoresced with the VI Light. This tends to be more effective if the tissue is evenly pigmented rather than mottled.
  
  Many fish have transparent tissue (adipose eyelids, fin membranes, clear boney tissue, etc.), but tag retention varies by body location and species. For example, the adipose eyelids of salmonids have generally proven to be suitable for VI Alpha tags, but implants into similar tissue in mullet (Mugulidae) have been rapidly shed. Buckmeier and Irwin (2000) found that 100% of VI Alpha Tags implanted in the dorsal fin of channel catfish Ictalurus punctatus were shed. However, researchers with the Iowa Department of Natural Resources developed a successful method of implanting VI Alpha tags into the tongue of flathead catfish (Pylodictis olivaris). The size of the tagged animal is also important. Shedding rates from adipose eyelids of salmonids less than 150 mm total length can be excessive while retention in larger fish often exceeds 90%. More on Adipose Eyelid Tissue here.
  
  VI Alpha and VI Elastomer Tags are widely used for individual identification of amphibians as an alternative to toe clipping. Tag retention tends to be nearly 100%, although the visibility of the tags varies based on the pigmentation of the overlying skin.

  VI Alpha Tags are not as widely used as VIE, but there are also many publications available that describe their use. In thick skinned, or heavily pigmented species, the numbers may not be visible, so it is important to consider the species to be tagged and the location of the tag. For example, Clemas et al. (2009) found that the pigmentation of Litoria raniformis obscured the tags, but VI Alpha were reliable for tagging large Litoria ewingii. On the other hand, Heard et al. (2008) was able to tag juvenile Litoria raniformis with VI Alpha tags and found they remained readable. As with VIE tags, using the VI Light dramatically improves the detection and readability of VI Alpha tags, sometimes even through highly pigmented skin.
  
  Measey et al. (2001) found there to be no negative effects of VI Alpha tags in a legless amphibian (Gegeneophis ramaswamii), and further stated that when individual identification is necessary that these tags are the “most promising” of the investigated tags. Buchan et al. (2005) tested VI Alpha in a number of species, and concluded that VI Alpha “appears to be an effective and low cost method for individually marking and identifying amphibians”. Kaiser et al. (2009) evaluated and used VI Alpha Tags to track individual Dendropsophus microcephalus.
  
  Osbourne et al (2011) discuss the use of VI Alpha tags in juvenile ambystomid salamanders and provide extensive detail about their application and readability.
  
  VI Alpha Tags have been used to identify individual hatchling turtles by gluing them to the carapace (Rosenburg & Swift, 2010).

Visible Elastomer Tags (VIE) for Research Big Kits ²⁵

$ 1,315.90 USD

This product is sold by BIOWEB Global in LATAM, but if you are in United States or Canada please contact the vendor Northwest Marine Technology directly.

Don't cut more phalanx, fins neither ears.
Now you may use advanced tags.

NOTE: If you need less colors check the smallest kit of 6 ml. Also is available the trial pack for starter projects.

Visible Implant Elastomer (VIE) is a two-part silicone based material that is mixed immediately before use. VIE tags are injected as a liquid that soon cures into a pliable, biocompatible solid. The tags are implanted beneath transparent or translucent tissue and remain externally visible. In many amphibians, VIE tags are even visible through darkly pigmented skin. VIE tags are widely used for marking an ever-broadening range of finfish, crustaceans, reptiles, amphibians and small mammals. Check some papers below. Extensive information about using VIE is available in the Visible Implant Elastomer Tag Project Manual (English PDF 294KB;  Spanish PDF 217KB).

VIE is available in six fluorescent and four non-fluorescent colors. The fluorescent colors are highly visible under ambient light and provide the option of greatly enhanced tag detection when fluoresced with the VI Light.

Proper color selection is a vital part of good experimental design. Your choice depends on how much contrast you need with the background pigmentation, how many different colors you require, and the type of light you will use to fluoresce the tags.

VIE is a medical-grade, two-part silicone based material that is mixed immediately before use and then injected as a liquid that cures into a pliable, biocompatible solid. Immediately after mixing, the user will have between 45 to 60 minutes (in warm environments) and 2 hours (in cold environments) of working time during which the tags can be injected.

The time that the prepared elastomer can be used (the "working time") depends on the temperature of the place. At normal room temperature (20°C), it usually lasts 45-60 minutes before it is too thick to push through the syringe. It lasts longer when it's colder and less when it's hotter. Working time can be greatly extended by keeping the unused prepared elastomer on ice as much as possible.

For unmixed elastomer, you can store it for one year from the date of purchase in a cupboard, away from sunlight or heat. The unmixed elastomer should never be stored in the freezer.

Generate a Coding Scheme

While VIE is primarily used for batch identification, you can generate a VIE coding scheme by combining multiple tags, tag locations, and colors. For example, researchers tracking seahorses used this method to distinguish more than 500 individual seahorses at one time.

Six fluorescent colors (red, yellow, blue, orange, green, and pink) and four non-fluorescent colors (black, brown, white, and purple) constitute the only intrinsic VIE codes. If you use just one tag per fish, the number of unique codes is simply the product of the numbers of colors used and the number of tag locations.

However, if you inject two or more tags in each animal, in combination with several different locations and colors, you can generate an extensive VIE coding scheme. In any tagging program, it is important that all of the study animals have the same number of tags. That way, there can be no confusion between animals which lost tags and those which began with fewer tags.

¿How Many Codes?

Calculate the number of unique codes you could create using the formula:

[L!/(L-N)!N!] CN

Where: C= Number of colors used, L= Number of body locations and N = Number of tags per animal.

For example, three body locations used with four colors (C = 4, L = 3, N = 3) would provide: (3!/0!3!) 43 = 64 unique codes. Recall that 0!=1.

You can download two softwares to do this automatic calculation. NMT Calculator or Salamarker. Both based in windows. Not available for iOS.

Visible Elastomer Tags (VIE) for Research Kits 6 ml (Two Colors) ²⁵

$ 284.25 USD

This product is sold by BIOWEB Global in LATAM, but if you are in United States or Canada please contact the vendor Northwest Marine Technology directly.

Don't cut more phalanx, fins neither ears.
Now you may use advanced tags.

NOTE: If you need more colors check the biggest kits of 24 and 60 ml. Also is available the trial pack for starter projects.

Visible Implant Elastomer (VIE) is a two-part silicone based material that is mixed immediately before use. VIE tags are injected as a liquid that soon cures into a pliable, biocompatible solid. The tags are implanted beneath transparent or translucent tissue and remain externally visible. In many amphibians, VIE tags are even visible through darkly pigmented skin. VIE tags are widely used for marking an ever-broadening range of finfish, crustaceans, reptiles, amphibians and small mammals. Check some papers below. Extensive information about using VIE is available in the Visible Implant Elastomer Tag Project Manual (English PDF 294KB;  Spanish PDF 217KB).

VIE is available in six fluorescent and four non-fluorescent colors. The fluorescent colors are highly visible under ambient light and provide the option of greatly enhanced tag detection when fluoresced with the VI Light.

Proper color selection is a vital part of good experimental design. Your choice depends on how much contrast you need with the background pigmentation, how many different colors you require, and the type of light you will use to fluoresce the tags.

VIE is a medical-grade, two-part silicone based material that is mixed immediately before use and then injected as a liquid that cures into a pliable, biocompatible solid. Immediately after mixing, the user will have between 45 to 60 minutes (in warm environments) and 2 hours (in cold environments) of working time during which the tags can be injected.

The time that the prepared elastomer can be used (the "working time") depends on the temperature of the place. At normal room temperature (20°C), it usually lasts 45-60 minutes before it is too thick to push through the syringe. It lasts longer when it's colder and less when it's hotter. Working time can be greatly extended by keeping the unused prepared elastomer on ice as much as possible.

For unmixed elastomer, you can store it for one year from the date of purchase in a cupboard, away from sunlight or heat. The unmixed elastomer should never be stored in the freezer.

Generate a Coding Scheme

While VIE is primarily used for batch identification, you can generate a VIE coding scheme by combining multiple tags, tag locations, and colors. For example, researchers tracking seahorses used this method to distinguish more than 500 individual seahorses at one time.

Six fluorescent colors (red, yellow, blue, orange, green, and pink) and four non-fluorescent colors (black, brown, white, and purple) constitute the only intrinsic VIE codes. If you use just one tag per fish, the number of unique codes is simply the product of the numbers of colors used and the number of tag locations.

However, if you inject two or more tags in each animal, in combination with several different locations and colors, you can generate an extensive VIE coding scheme. In any tagging program, it is important that all of the study animals have the same number of tags. That way, there can be no confusion between animals which lost tags and those which began with fewer tags.

¿How Many Codes?

Calculate the number of unique codes you could create using the formula:

[L!/(L-N)!N!] CN

Where: C= Number of colors used, L= Number of body locations and N = Number of tags per animal.

For example, three body locations used with four colors (C = 4, L = 3, N = 3) would provide: (3!/0!3!) 43 = 64 unique codes. Recall that 0!=1.

You can download two softwares to do this automatic calculation. NMT Calculator or Salamarker. Both based in windows. Not available for iOS.
