Mice around front porch

Hi folks,

We saw a few mice running down from the front porch to the lawn. We got rid of a couple of them using mouse traps and then saw a third one.

We have called pest control and they've said they will check the attic and probably use some sort of poison to kill them. However, the understanding is they will die wherever they are.

Q: Is it safe to have dead mice in the attic or under/inside porch or other parts of the house?

Q: I have attached a couple of images, we are looking to fill the hole in the side concrete/wall under the porch. My concern is the big gap under the front steps will remain problematic. Does anyone have viable and cost effective solutions for fixing the gap under/between the steps?

There are also holes in the garage walls. Apparently they did this for installing cameras.

We recently purchased this house, so we don't have too much insight about this issue. Guessing it existed previously as well.

Are you sure they are mice and not voles? I had a problem with voles a couple of years ago. I got rid of their food source (flowering shrubs etc) and trapped a few of them. I don’t see them as much anymore. I believe they come and go - the presence of their predators (or absence) in your neighbourhood will affect their numbers.

Definitely not moles. Mice for sure.

I believe some neighbours may have them in their yards as well.

Haven't seen any inside the house. However, the hole in the wall under the porch concerns us. We are quite sure they are coming out from there onto the porch.

We have someone from a pest control company coming. Anything in particular that we should ask or be mindful of?

He said voles, not moles.

I would not call in pest control if the mice are outside. Rodents typically come inside for the winter (some - like voles - typically tough it out in burrows under the snow).

Usually the summer is not the time for mice to enter a house. There are exceptions, of course, and you should take precautions like sealing up holes and cracks. That being said, no house can be so well sealed as to be a barrier against a determined or lucky mouse.

Next time you see or trap one, measure its tail and google the difference between voles and moles. It's a good idea to trap either of them if they are too close to your house but I wouldn't worry too much about voles - unless you prize your garden.

If you do lay outdoor traps, put them inside a plastic covering / box so you don't unintentionally injure or kill an animal you are not targeting. I find that a 3/4" hole drilled in one side of the box is sufficient to keep out birds, frogs, etc.

They're just field mice, I wouldn't worry about them. Just set up a few traps and keep the population low. They're everywhere, they just happen to make your porch their home.

Can use some chicken wire under those steps to seal off the gap. Simple solution.

Killing mice outdoors is like swatting at mosquitoes. 1000 to take the place of every 1 you kill.

But, you should absolutely seal up those holes in the garage ceiling. Not only for critters, but for fumes. Garages need to be air-tight to the rest of the house. Even if you don't park in your garage, the ceiling needs to be sealed up.

The gap under the front stairs isn't a problem unless somehow it's open to the house, which of course it isn't. You should be pulling up those 24 x 24 patio slabs and raising that walkway to the bottom edge of the stairs, so the risers are all the same height. It's a major tripping hazard and to be particular about it, against code.

Don't waste your money. They'll charge you a few hundred bucks and all they'll do is put poison everywhere.

Animals need a place to nest and the hole under your porch is a good place to do that - it's cool and free from the elements. As long as they don't come inside, there's not much to worry about. They are nocturnal so you won't see them much.

@Copper1212, it was a typo/auto-correct. Rest assured, I'm aware he was referring to voles.

Thank you everyone for the input. Since we had an appointment booked for today, the pest control specialist checked the attic and said it's clear. I understand what we see are likely field mice, which is a relief.

The pest control specialist suggested putting baits to get rid of mice. He said this would help get rid of mice around our house, and mice from the neighbours won't come over, as they tend to stay where they are. I'm not sure if that is entirely accurate. I would think field mice probably run around and go from one house to the other.

We will try to take care of the holes in the garage wall(s). Also, hoping to find time to cover the hole under the patio. The only concern remains bbq in the backyard. In the past (previous house), we had mice build a nest in the bbq. We are hoping to avoid it from happening again. Open to suggestions around it.

Thank you!
