You may need to get another type style of pole.One thing that is important is that if you dont cover your cage traps you can have a very nervous and edgey skunk when you arrive. That is your first mistake if you dont cover your traps on each set up.Covered traps provide better security for any animal. They just dont feel naked, exposed and vulerable therefore they will be more workable in most cases.
A percent of all skunks approached will be naturally defensive just is their nature. Also the time of day you do your pick ups can influence your animals disposition as well.
Covering traps is just standard procedure with our working policy. We use 4 point hingeing covers so you can slowly flip one flap or another up and over the trap to make access to the skunk for your best dispatch delivery.Also as stated our poles go thru 1" wire grids easily and if you have 1/2"-1" wire grid you need to cut some access holes on the trap to allow you access to the animal depending upon its position in the trap.
I have dispatched thousands of skunks in my days fur trapping and adc trapping. It does require some practice and understanding to run a high 99% efficiency. Confidence in your method is like many things, it helps to guide you on each future consecutive procedure.
