I use to do alot of contract Beaver trapping and blasting for Georgia Pacific. Trapping them is the only way to control them effectively. You will need go buy yourself several dozen Conibear 330 traps for your 2 mile stretch. Get your waders on get out in their water system and look for the paths they frequent. These are easy to find as the bottom of the water will be clear trail where they are moving. Look for natural bottlenecks, logs they are going under and place your traps in those places. Use a good sharpened 1.5-2.5" green stick to stake the trap in those locations. You will also need to take several green sticks and drive those in the ground in the shape of a "V" leading to the trap. That helps funnel them to the trap. If there is a way for them to go around the trap....they will. Make sure all your traps are under water so once they are caught in it, they drown.
If you dont see natural bottlenecks to place your traps, then near the banks where they exit the water you can set your traps. Use the same V formation of sticks stuck into the ground leading up to the trap. You may also need to find a good sized log and place it over the path to force them to go under the log and into your trap. Always use the V formation of sticks to funnel them otherwise you are wasting your time.
Check your traps daily and pull dead beavers and reset. You will catch snapping turtles so those need to be cleared. They can hold their breath for a really long time so if you do catch one, be careful as it can still be alive and bite you. Eventually you will get the beavers under control, but you will need to continue trapping on the boundaries of your property even after you eliminate them on your property
family planning gold coast. Once beavers on neighboring properties reach maturity, they leave their family ponds and head up and down river in search of new territory for themselves. So you will continue to have beavers coming on your property up and down river and that will need to be monitored and trapped.
Once you have caught a lot of beavers and start seeing activity levels drop, fewer signs of fresh movement, activity on the dams, etc. Then you can blast the dams. You can use agricultural explosives to do this. You will need to find a vendor near you and complete the forms to be cleared for purchase and use. (this process may have changed, not sure. Its been a long time since I have bought KinePak explosives). When blasting, walk out on the dam and take a spade shovel and open a small slot on the water side of the dam in the mud. Put your explosives in the slot. Usually 1-2pounds is all you need but it does depend on how big the dam is. Putting it on the water side uses the weight of the water to push the dam out once the blast goes off. If you put the explosive anywhere else you are wasting your time. Use electrical blasting caps not fuses, they are more reliable. I used a roll of telephone wire to get out to a safe distance before blasting.
