Mouse germs

Steven Mechanic Spokane, Washington Posted   Latest   Edited  

I'm interested to hear what other mechanics do about mouse nests and the potential for germ transmission. Today I have an intake manifold that has to come off and there is a mouse nest down in there all along the cylinder head to intake manifold. My procedure is to spray all the poo and pee and nest with brake clean in hopes that it will kill any germs that may still be alive. Then after it drys most of the way I blow it out with compressed air. I would vacuum it out but it is too deep in there to get the vacuum nozzle in there. I wear a respirator mask when I blow it out, and eye protection of course.

Update:

Thanks to the members for warning me about hantavirus. I've done some web searching and you really don't want the mouse stuff to get kicked up into the air. This is the main way that people get hantavirus. Therefore, no vacuuming or sweeping or blowing mouse stuff up unless you have soaked it in a bleach solution for about 10 to 15 minutes, and it should be wet when vacuuming it up so there is no mouse dust to go airborne.

Steven: I use a mister bottle and spray a mixture of bleach and water onto the debris and let it soak then rinse off with hot water. The debris can then be swept up and disposed of in a plastic bag. I then can dry the area with compressed air. I'm sure there are less time consuming ways of doing it but stirring up a cloud of dust and having it potentially getting past a mask could prove harmful…

Great idea, but it could cause damage in some areas. Chlorine is very damaging to some polymers and elastomers, such as intake manifold gaskets and fuel injector o-rings. Thank you for the link, I wasn't aware of the level of danger.

I scoop out as much as possible with gloves and a mask on then shop vac out the rest and then spray the area with hydrogen peroxide. I don't blow it out with air until I 've cleaned it all up and sanitized it.

Hi Steve - I start with removing the large chunks of bedding, Then I spray it all down with dish soap and water solution (any surfactent solution will work), and spray it all off with a hose. I basically treat it just like asbestos. Anything you can do to minimize air borne dust should be the goal as those little vermin are carriers of hantevirus. I also wear a good paint booth quality…

Steven, What ever you do, don't use compressed air on a mouse nest. Here in the Southwest, we have a deadly disease called Hantavirus. Hantavirus is carried by mice and distributed through their feces and urine. About 10 years ago, we lost a local man who was cleaning out an old cabin and didn't know about Hantavirus. I would wash the nest out with high-pressure hot soap and water if…

Thanks guys. I was not aware of hantavirus. I'm going to be more careful from now on. Have a good day!

Steven: Thanks for the update. I'm sure there are a few people who are a little more educated after this. We already have enough "VIRUS"problems to worry about. Be safe!

I use the hydrogen peroxide mix it kills stuff at the enzyme level and that is important so I keep a jug around but right now you find it hard to find due to the other virus going around, the one thing I have to tell my customers is not to put poison in the car use a cheep electronic pest control because once they die in your car the smell is wow and almost imposible to get rid of but the…

I need to try that. And I agree, using poison is a terrible idea! I don't understand why it is so common, when mice and rats are incredibly easy to trap and dispose without the risk.

Remember to keep the mix out of sunlight . It breaks down with sun light. H2O2 works well at mold and mildew control as well. The last few yrs I have been dealing with that issue in some rentals of mine.
