Thanks, guys! That makes it much clearer!
As a life-long scientist, my statement about āstudies showing a vertical jumping height of four feetā was very un-scientific of me, since I have been unable to find the source for the claim āstudies show the eastern grey squirrel has a vertical jumping height of 4 feetā that is posted on the internet.
I suspect you know more about the jumping abilities of the eastern grey squirrel more than any scientist though.
The original 5" pipe to my bird feeder was set at 4 feet. I had one squirrel that would jump and be able to propel himself from friction (I assume) for a few inches up the pipe to reach the feeder. Now my pipe is 5 feet and I hadnāt had one reach the bird feeder in years. Your squirrels may have developed extra-ordinary jumping skills from selective breeding. Are you using cone baffles or pipes? I just feel that as long as the bottom of the cone is at least 4ā from the ground it would stop most non-Olympian squirrel (Pipes I feel need to be higher).

I actually use both because lots of times first branches begin start too low for squirrels so I create a cone using the scaffold branches if I canāt afford to cut them.
When I have a straight trunk of at least 4ā I may be able to get away with a greased cylinder about 32" long- for coons no grease is needed and usually they wonāt reach beyond about 3ā to get to wood.
The cylinders can be installed in about 5 minutes, tops, when you have materials ready, but making the cones against branches is a bit of an acquired skill that my assistant is amazingly adept at since Iāve had him do most of the baffling the last few years. Iād say 15 minutes is the most time he spends on the most complex of systems which I canāt really describe.
My wife has been attempting to get photos from my phone to this topic for the last hour. For some reason thereās something wrong with my phone.
Wowā¦Interesting. Where did you get the material for your inverse cones?
My wife accidentally put up two of the same photos. The top flashing is the thinnest 20" wide stuff home depot carries and the lowest is pre-painted 24". Together they provide enough distance. Lower baffle is stapled on first. We painted the aluminum of the upper part with spray paint after installation. Then we paint the whole thing with a blend of tan axle grease (the red is SO ugly) and motor oil so itās not too thick but has some staying power. Straight grease actually provides traction on cool nights, apparently. I use a 1 gallon container with a screw top to shake mix the oil and grease combo- best done in the warmth of day.
Sorry, I have no pictures of straight cylinders.
The single picture is what we do with hardest to protect trees. Squirrels can keep going up narrow cylinders and remove the grease, but theyāve yet to defeat the wide cylinders (much wider than most trunks) that start at the ground so squirrels wonāt slip between aluminum and the trunk. Like rats they donāt need much space and chipmunks need almost nothing.
We used to use duct pipe, but it is a PIA to work with. Itās the more standard method and you can purchase 5ā lengths of it at HD.
Itās much easier for squirrels to muscle up a narrow diameter baffle. But if you keep it greased they rarely defeat them.
I protect hundreds of trees this way every year.
Beautiful orchard, BTW.
His squirrels are among the Olympians. When a branch bends with fruit below about 5.5 feet they jump aboard. Located in Greenwich CT.
You should see the rest of his property, he has me manage about 15 pretty big apple trees against a stone wall in the middle of a very formal, highly maintained French style landscape.
Someday I will post a picture of those apple trees, they are so beautiful in their location.
Thanks Alan for posting pictures of your method.
I did that several years ago and it was effective against a chipmunk that was stealing peaches.
Managing tree vigor must be a task in such places with that high input grass.
Actually, typical of many homes in the area, they only added enough top soil to assure turf would survive (which is hilarious given the cost of the home). The trees in that area are not excessively vigorous, the problem is a row of Maples to the south of the trees closing out the canopy by about 5ā a year. Light is already inadequate and plums suffer a lot of black knot.
Glad you posted these photos.
These baffles all but saved my business. Customers will only pay so much for so long for nicely pruned fruit trees that are barren of fruit.
Where I am, customers without deer fencing need the high branches anyway.
Iām surprised none of my customers ever opt for an electric deterrent so we could maintain a pedestrian orchard. Itās partially because it isnāt a service I offer and fence companies around here donāt either.
BTW, at that Greenwich property the squirrels and chipmunks take all the apples every other year or so. The baffles canāt work there because trees are against a wall. Because itās the middle of the property Iād have to make the baffles more attractive to be acceptable anyway.
If squirrels liked green apples as much as green peaches or pears, theyād never get any apples. I grafted Honeycrisp and Ginger Gold on a couple of the apple trees and heās only tasted either one on a single season when the squirrel population had crashed.
Too bad that cats are totally un-trainableā¦My cat is only interested in hunting squirrels five minutes a dayā¦The rest of the time she is laying around being totally useless.
Some dogs are amazing at controlling squirrels in their territory. One of my major clients had one of those, but lyme disease and old age have cost me that alliance.
Decided to make a squirrel baffle for my peach tree.
This one is working out ok so far. I have a layer of grease on the trunk and baffle.
This one didnāt work too well since itās too low to the ground. Had to put the metal wire back. But itās no game for squirrels. At least it takes time to finish it.
My squirrels will usually jump 5ā to reach the first limb. some olympians jump 6.5ā
This seems to be working for raccoons:
I left the chair a little closer than that and there were raccoon prints on the chair and lower edge of the upper roll, but not higher.
Coons and possums donāt compete in the high jumping categories. What may surprise you is that woodchucks really can leap quite high. A very sane and sober client of mine claims he saw a fat one jump 5ā to beat a baffle on peach tree I manage for him. Fortunately, they donāt tend to eat a whole lot of peaches in a day- only 2 or 3 based on what Iāve seen on my property.
Thatās not my orchard, it is one of my wealthy clients and you should see the rest of the landscape that is tended with a platoon of workers once a week. Some of my clients have an in-house platoon working their landscapes 5 days a week. I trap and shoot my vermin.
I am not fond of wells that are edged out as a divide between grass and tree plot. I prefer a mulched mound for establishing trees and usually just mowed grass once trees are established- as long as the crew doesnāt tear up the bark with a whacker. If thatās the case, a small ring of shredded wood helps block weeds and keeps the whacker string away. It suppresses weeds better than wood chips because it matts up tightly.
