Repelling Snakes with Snake-A-Way
Over ten years of independent research and follow-up tests were also conducted by DR. T's Nature Products. Inc. The effectiveness of the repellent is demonstrated by the following experiments performed with various species, and the products has been found to have a rate of efficacy that varies from 17% to 100% depending on the individual species.
75% Coluber constrictor Black Racer
91% Crotalus adamanteus Eastern Diamondback rattlesnake
91% Crotalus atrox Western diamondback rattlesnake
91% Crotalus horridus Timber rattlesnake
91% Crotalus lepidus Rock rattlesnake
91% Crotalus ruber Red diamondback rattlesnake
91% Crotalus viridis Pacific rattlesnake
17% Elaphe guttata Corn or red rat snake
21% Aakistrdon platyrhinos Cotton mouth
47% Elaphe obsoleta Yellow rat snake
100% Heterodon platyrhinos Eastern hognose snake
100% Micrurus fulvius Eastern coral snake
50% Phython molorus Burmese python
100% Thamnophis marcianus Checkered garter snake
In as much as the normal behavior of snakes is to move slowly in a deliberate and investigatory manner, the experiments were devised to test the snakes responses to the repellent in as near to normal conditions as possible. In use, the granular product is spread on the ground across an area where it is desired to prevent or discourage snakes from entering. Preferably, the granules should be spread in a strip 10-30 centimeters wide, although generally the wider the strip the better. In this manner, an odor barrier is provided that snakes are reluctant to cross. Additionally, a smaller amount of the product may be scattered in a diffuse or non-continuous manner just beyond the strip, on the side away from the area to be protected. This added scattering of the repellent serves to lessen the probability of occasional snakes wandering beyond the strip. After 2 months, a group of 16 snakes was again re-tested. In this test the branches of the "Y" were reversed, so that the repellent strip was at the branch opposite from that in the previous test. Moreover, the repellent used was five weeks old ( i.e., it had been on the ground outside, but protected from heavy rainfall). Eleven snakes exhibited overt avoidance of the of the repellent, and four snakes crossed the repellent. Two of the snakes which crossed the repellent exhibited avoidance behavior first, eventually moving across the repellent strip while rubbing the head against the ground, seemingly attempting to escape from the repellent. Repelled snakes showed no hesitation to enter the opposite (benign) branch of the "Y".
CONCLUSION AND DISCUSSION
The principal conclusions from this study are as follows.
(2) The efficacy of the repellent varies with taxon: some species are repelled with remarkable effectiveness, while others are not. However, all species tested, exhibited some degree of behavioral avoidance of the repellent.
(3) There are circumstances in which individual snakes of all species tested will cross a strip of repellent, so the product cannot be regarded as an absolute barrier to these reptiles. Such situations are expected to be rare in natural environments, however, and
(4) Use of the product can be expected to reduce significantly the occurrence of snakes within areas that are to be protected by recommended use of the product.
