Mice

    Hi Everyone, 

    I am dealing with a mice issue at my museum. I currently use sticky traps for insects and snap traps for mice.

    Although, our Museum also is AZA accredited and we are required to be as humane as possible with animal treatment, even with pests. I am trying to see if there is an effective trap that is more humane for catching mice. The Curator of Wildlife at the Museum suggested using live traps but I have no experience doing this and have not seen Museum professionals suggest using live traps.

    Does anyone have general recommendations for getting rid of mice?

    Has anyone had experience using live traps? Do you recommend or not recommend using them in museums?

    I appreciate any help!

    Thanks,

    Hi Nikki-

    I'm currently acting as C2C Care Monitor and wanted to pass along some resources while I reach out to our community experts on your question. See links below to some C2C Care webinars and other resources that might be of help and more soon!

    Hi Nikki!

    Although it might seem like live traps are more humane, the consensus among IPM professionals is that the snap traps with the quickest possible death are the most humane. This is because mice can die fairly quickly in the live traps (in just a matter of an hour or two, in my experience), and while they are trapped, they are stressed. To successfully implement a live trap system, you'd need constant vigilance, which museums cannot do. 

    I work for the National Park Service and our official policy is that snap traps are more humane. 

    Check out the Rodent page on MuseumPests.net and especially this tip sheet for setting the most effective snap traps. 

    I also like to glue my snap traps to a piece of thin cardboard/cardstock so that it's not only easier to set the trap and move it into position along the wall, but also provides a wide buffer if I do catch a mouse. This is especially prudent if you live in an area with hantavirus and need to protect yourself. 

    And finally, I'm attaching some Mouse Trap Tips that I gave as a talk at the AIC annual meeting Tips Luncheon a couple years ago. It kind-of summarizes the above information. 

    Good luck and I hope you're able to figure out how they are getting in, so you can exclude them and not have to worry about humanely killing them. 

    Best, 
    Fran

    Hi Fran, 

    Thank you so much for your response. I am glad I asked! I was told that snap traps were the most humane as well so I was hesitant when being told to use live traps. I will take your resources and bring them to our Curator of Wildlife. 

    Thank you!

    Hi Nikki,

    Speaking as a mammalogist working in a natural history collection, I can tell you that snap traps are one of the most humane ways to manage rodents--they are instantaneous, have high efficacy (i.e., rarely leave the animal alive) and do not cause a cascade of environmental harm (unlike poisons). Additionally, if you were to switch to live traps (such as Sherman traps), do be aware that many US states do prohibit the capture of wildlife for relocation--do look into local and state laws before switching if you choose to do so. If you were to switch to live traps in a state that prohibits release of trapped wildlife, you would need to euthanize them by another method; while I am not familiar with AZA guidelines, I'm sure they have opinions on euthanasia techniques, and that could turn the problem of rodent management into one of rodent trapping and euthanasia, which is a bigger project. The American Society of Mammalogists (ASM) does issue IACUC guidelines on wild small mammal euthanasia, if you choose to go this route. We at the MCZ do use snap traps for management of rodents in our collections (and sometimes we add those very trapped rodents to our collections. Our usual snap trap brands are Victor and Museum Special). And definitely check out the IPM resources Robin posted as well.

    Best,

    Hi Madeleine, 

    Thank you for your response, It is so helpful to hear from other professionals on this topic. At my Museum we have live animals like porcupine, fox, bobcat, otters, birds of prey, etc. as well as historic objects. The Curator of Wildlife often uses the mice he catches in live traps to feed the animals we care for at the Museum. So, we would never be releasing the mice back into the wild. 

    I will take your advice and bring it to the Curator of Wildlife. I agree with you that snap traps are the most humane. I just need him to get on the same page!

    Thanks,

    Hey Nikki,

    You're not alone in dealing with mice. I'm at an ag museum on just about 40 acres and we have to deal with mice just about every fall and some springs. We started using live traps and they have been great. We have the space to let them out either on the edge of the property near the creek or near the trees. Usually on of the maintenance team will release the mouse, but in reality its anyone who is free and doesn't mind dealing with mice.

    Good luck with the mice!

    Hi Sarah, 

    Thank you for responding! My Museum is in the middle of a forest so its not surprising that we have a mice problem. We have live animals at our museum as well as historic objects, so the Curator of Wildlife would use the mice from the live traps to feed the animals we care for (birds, bobcat, etc.) and we would not be releasing the mice back into the wild. That is why I am unsure of how humane it would be. 

    Thank you for your advice!

    Hi Nikki, 

    I live in an area with high rodent population and regularly live-trap mice in my house. (Luckily we do not have a mouse issue in the collections!) The issue is always whether the mouse survive until you next get there to check the trap (otherwise, a snap trap is the more humane option). Instead of using the small live traps that are marketed for mice, I use a trap designed for rats so that I can leave more food. I make sure to include a food with moisture such as apples or melon rather than just peanut butter. I also balance some of the food on the trigger so that it will release with the smaller body weight of a mouse.  Still, the traps need to be checked at least once a day if you are going to live trap, and twice a day is better.  You can contact me directly if you want information on the trap I use.

    Hi Samantha, 

    Thank you for your input. That is a great idea to get bigger traps and including food with more moisture.

    Having the time to check live traps enough is my concern as well. 

    I will pass all this information along to my colleague!

    Nikkie,

            A few years ago, a friend had a big problem with pack rats in her luthier workshop. She used have-a-heart traps and would take the traps to locations miles away from the workshop to set the pack rats free. There was one recognizable pack rat with a nicked ear that kept coming back - after he returned from 15 miles away, she finally began using snap traps. It took time to remove the pack rats and find their nests. The larger problem to think about with rodents is the prevalence of diseases like plague, tuleremia, and hanta virus in some desert settings. 

    Good luck!

    Susan

    Hi Nikki -- 

    From what you were saying earlier, this also sounds like it might be a great opportunity for interdivisional cooperation -- if your wildlife curator is invested in trapping live mice (hey, free food is not a bad thing), then perhaps work out something with them and their staff to help monitor the traps, assuming special access isn't available, etc. That way you get to ensure the traps are checked frequently, and the wildlife curator gets their mice!  

    Or you could get a cat :)
