Opossum Facts

Opposums are the only marsupial in North America. They are fascinating animals on several scores. They are excellent climbers with a prehensile tail that can grasp branches. They have opposable thumbs on the rear paws that give them the ability to open containers like your garbage cans.

However, they don’t live long with a lifespan that is less than two years. It’s curious given the fact that they have superior immune systems that protect them against bees, snakes, and other threats. You may wonder do possums carry rabies. Their natural immunity protects them on this front too as they rarely get it.

What You Need to Know

Before buying the best possum poison, there are several things you must research to do it safely and legally. Some states such as Minnesota and Wisconsin classify opossums as a game animal. That means a trapping and hunting season with requirements for licensing and permits.

Fortunately, you may have some latitude for taking matters into your own hands as a landowner. You may not have to get a license to take nuisance wildlife even out of season. The laws vary when it comes to renters or other individuals who dispatch the animals. Violations of these policies mean costly fines, so it pays to learn about them up front.

If you choose to use a poison, you must use it as described on the label. It’s a violation of federal law to do otherwise. Many products are broad-spectrum. That means they pose a risk to non-targeted species including your pets. It’s imperative to follow the instruction precisely regarding the use and disposal of them.

You should also take care when using any poisons near water sources like lakes and streams. Likewise, only put them in spots where an opossum will find them. For example, don’t put something like Sweeney’s S6006-4 Mole & Gopher Poison Peanuts near bird feeders since many other species eat nuts too.

How to Use Poison

Your best results begin with the proper placement. Look for signs of activity such as eaten garden plants, toppled garbage cans, or damage to your house or outbuildings. These things will tell you what areas the animal uses regularly. It can also reduce the risk of hurting other non-targeted wildlife.

Understand how the poison works and how quickly it will act. Remember that an affected opossum will likely try to return to its den even if it’s in your attic. It’s essential to supervise your pets when outdoors after using these products. Some toxins may also harm other animals who may feed on the carcass, including your dog.

Preventing a Recurrence

Another thing you must do is to take steps to avoid the problem happening again. Simple tasks such as rinsing your garbage cans periodically and never leaving pet food outdoors can go a long way toward prevention. Also, repair any broken screens, vents, or holes along your house’s foundation.

You should also fence off the area under your deck or porch which can also provide shelter for an animal. The same precautions apply to the upper reaches of your home. Trim all branches that hang over your roof or are within 10 feet of the building. They can provide access to your attic and create a host of unpleasant consequences.


The best possum poison works quickly to get rid of a pest fast to minimize your handling and use of these toxic substances.
