Personally, I find the white color of PVC pipe not very aesthetic, but well, solving a problem does not require aesthetics.Īmong the same category of plastics, there is also the polyethylene pipe (PE), they are much less rough than the common PVC pipe, with a roughness factor of 0,002 besides its color is black, which seems to be much more aesthetic.Ī polyethylene pipe could triple the difficulty for a squirrel to climb it in relation to a PVC one, and if you think that the squirrel can use its nails to climb it, think about it, if you use a suitable diameter it would be an almost impossible task unless it is a super squirrel. PVC pipes on average are less rough than metallic pipes. PVC pipes have an absolute roughness of 0,02 (k: mm), if you are confused by this unit of measurement to give you an idea, let’s say that a rough concrete surface has between 2-9 (k: mm). The most recommended for posts should be 2″ and up, because remember that the less friction there is, the more effective the post will be, the wider the post, the less friction and grip the squirrel will have. PVC pipes can really be a solution to the problem of climbing squirrels, PVC pipes are classified in the category of plastics in construction with different dimensions in inches in reference to their diameter.
The squirrel depends a lot on the double articulation of its hind legs to be able to climb, it does this by clinging to the surface, so to measure the efficiency of the tubes I will be taking as an important parameter its roughness or rather, the smoother the tube the more efficient because it is more difficult to climb.Īfter this brief introduction (with a super redundant opening sentence), let’s get started. The less rough and the less friction a material produces, the more difficult it is for a squirrel to climb it, the friction force is what a squirrel uses to cling to a pole to climb it. In order to have a logical and fair material analysis factor, we will rely on a friction factor as well as a roughness coefficient, I do not mean something super scientific, but obviously each material has its own qualities. It is also common to see complementary methods used for these poles, such as greasing, petroleum jelly, electrification, and other methods, all to prevent squirrels from climbing them.
#PREVENT SQUIRRELS FROM CLIMBING BIRD FEEDER POLE FREE#
These poles, which are usually used outdoors attract squirrels which can climb and take free and easy bird food, which materials would make this squirrel habit more complicated? It is already known that squirrels can climb trees with incredible agility, both up and down, squirrels have certain physical qualities that facilitate this task, also the bark of trees lends itself 100% for this purpose.īut what about the other more material? researching on the web I came across some concerns about squirrels climbing poles, especially bird feeding poles. Squirrels are excellent climbers (yes, I know, super redundant starting phrase) but this will be an interesting topic where we will be analyzing and comparing the different materials that a squirrel can or cannot climb, which of these materials is the ideal one, and some tips for their choice.
