If the mouse family has moved on or been evicted, can you not scrape out the debris, give it a hosing, and the turn it on for a bit to sanitize?

Take out the nest and put it on the ground away from your house. Mice carry ticks and other diseases. Then fire up the grill with no food on it. That will kill anything and burn up what's left. When cool, use rags or paper towels to wipe it out. Scrub the part that touches food and reheat. It happened in my grill and all is back to normal. It's nature.

Burn baby burn!!! ;)

I cannot stand mice. They are disgusting vermin and nothing more. You don't want mice that close to your house anyway. I don't care if they had babies or not, they would have to go. Then I would clean that grill with Ez-off and the pressure washer....about 3 times over, making sure every one of their turds was out of there. Disgusting!!!!!

Is there anything inside the pressure washer could damage? Do I lay it on its side, or get on a ladder? I love all critters -- okay, NOT venomous snakes -- but the idea of mouse crap and hair is just gagging me.

You can usually smell rat pee also which you may notice with the fire. I would have to buy new or give up cooking out. JMO

Is this a gas or charcoal grill? I would clean the grill first, get it nice and hot for at least an hour. Clean it again and reheat it again. I would get new grill grates though. I wonder how the mice got into the grill?

Rodents of course are going to smell a grill..I bet many grills get mice rummaging in them for food.

Husband needs to clean it up, then you can go in and do the deep cleaning. It will be ok. My cat brings us mice periodically, that are dead of course.

That was a very helpful video. Thank you, CO! Enduring, I don't know if my husband will clean the grill or not. He really hates doing any sort of chores. But now that he is retired, he is doing a few new things around the house, and doing most of the grocery shopping which is really helpful. I have sent him the video and told him to decide. If he wants to break it down and clean it, I will help him, but I can't do it by myself. I have always washed the exterior and scrubbed the bars and grates myself. Plus I do all the grilling. But honestly, I don't care that much about grilled meat. I could care less if we have a grill or not. So I'm going to leave it up to him. But I'm not going to sit and look at a dysfunctional, half-disassembled grill in the backyard for months on end. Right now I have the grates out. So it's gotta get clean, or she's outa here. We shall see.

Let me know before you curb alert, if it gets to that point. No clue where you're located but I'd be interested in acquiring it.

Okay, this is a really late response but we had the exact same issue. Mom was nursing her babies. We just assessed the babies age and waited for 21 days because they will have left the nest. Mom was still residing in our bbq solo. I gently scared her out, cleaned up the nesting and bodily waste left there. Removed the bbq’s ‘flooring’ so she couldn’t resettle in the middle of the night. Now, she can live her life as Mother Nature intended. This is the most ethical way to evict them. The bonus is I can sleep with a clear conscience. I used gloves and a face mask and hosed the bbq down after. I googled the reproductive cycle of a field mouse and learned when the babies leave.

You are a nice person and probably a mother who was thinking of the babies. We have a mama mouse right now in out grill ready to have babies. My husband said to me,let her stay and have them. i told him what you did. We were looking at new grills anyway. So once the babies can leave then we will remove them and dispose of the grill Thanks for telling your story.
