Giant House Spiders have taken over one of my outside deck boxes

[oregonprepper]

Hi, I have a large Rubbermaid deck box in my yard, containing some gas cans which I am supposed to rotate monthly (there are twelve jerry cans, one labeled for each month, and on the first of the month I rotate that month's can into one of our vehicles and refill - this way my stored gas is never any older than 12 months, well within the capabilities of Sta-bil). Anyway, I discovered in October that that corner of the box had been taken over by what looks like a Giant House Spider. I am in Willamette Valley of Oregon. I happen to like all wildlife, including spiders, and the network of webs that this guy (or gal) had built up around the cans makes it difficult or impossible to move them without destroying the spider's home, which I don't want to do. So I left October, November and December, thinking maybe I'll get to those in Spring, but today when I went to rotate January, which is on the other end of the deck box, I discovered another similar spider has also taken up residence there.

So, my question to you, the spider community, is simply this: When will I be able to get access to my cans again, without harming these spiders? I assume doing anything in winter would be bad, since this is their overwintering home. Are they guarding their egg sacks? If so, when will they hatch, will it be sometime in the Spring? Would the adult spiders be dying then, or do these Giant House Spiders live for multiple years? I just want to plan my access (to maybe move the cans to a different deck box that isn't in quite such a "wild" area) so as to do as minimal damage and harm as possible. As I said, I like spiders, I have no wish to wreck their lives or tear everything apart, especially if that would risk killing their kids (yet to be hatched).

Any advice would be appreciated... note that I'm not afraid of spiders, this isn't about "eww how do I get rid of them", I just want a plan that involves maybe timing (time of year?) that would be least disruptive to their life cycle, so e.g. for example if early summer, April-May-June would be a good time in between nesting where they could reasonably be somewhat dislodged without losing everything and just dying, or if there is some other time, or maybe no good time (which is a distinct possibility, I know)... just any advice on how/when to do this, please help me help them.

Thanks!

Can we see pictures of your setup?

I don't really want to disturb them again (I feel bad) but I can if necessary. In the meantime, it's just this box:

Amazon.com

And filled with these cans:

The 5 gallon red cans, basically just 12 of them, that deck box is perfect size for that. They go in four rows of three, so Jan-Feb-Mar on the far left, and Oct-Nov-Dec on far right. I put cedar slats on the bottom of the box to keep the cans off the plastic, since the boxes aren't completely waterproof and some moisture could get in.

There's just the usual webbing along the tops of the cans, and an annoyed looking spider sitting glaring at me from somewhere along the top of the cans or on the underneath of the lid. I'm always like, "ok let's see if it's clear this time.... okaaay that's a nope sorry to disturb you k thx bai".

If you really want a pic then I can go do that. I know I might have mis-identified these spiders but I really think that's who they are, based on my location and how they look.

Ok, I felt bad seeming like I'm wasting people's time here, so I just went and got a couple of pics. Sorry, not very good photos, it's kind of dark and cloudy today and the light isn't great, and I had to hold the lid up with one hand etc. But here is what I have, please feel free to ridicule my lack of expertise both with a camera and identifying spiders: (Note in the last pic, the spider is not very visible but is hunkering down on his/her web hanging from the underside of the lid). Also I notice that the photos make it seem like there isn't much webbing, but there really is. I would destroy quite a lot by dragging any of those cans out right now.

You may be able to carefully stretch/move some of the webbing to another surface, just be prepared for it to stick to whatever you try to move it with, and donate it to the cause

Could you replace the can with a piece of cardboard so she has something else to web to?

Do you experience freezing temps where you are? What’s the freezing point of gasoline? It may be insulating her…

I have tried relocating spiders before, from the fireplace etc, and I don't think I want to try handling them or their webs. It never goes well and I always seem to end up doing more harm than good. My wife jokes that "I have good intentions" and "I mean well" should send chills down every critter's spine in the area, sad face. I would rather just let them be until they are naturally moved on or died or whatever.

Where we are the winters are not usually especially cold, but there are always periods during each winter where it can get down into the 20s. For example we're supposed to get a couple of 24F nights over the next few days. But the spiders seem quite cosy inside the box, there is also a bench cushion on the top of the box which is possibly insulating it, and the box itself has double walls. Possibly the gasoline and cans is insulating too, I know liquid has thermal mass so it probably helps things stabilize a bit. I'm sure they are fine in the box over the winter, as long as the Well Meaning Monster doesn't keep coming and opening up the lid and leering in at them.

Not sure what the cost of fuel is for one of those containers, and therefore two (or however many months until it’s warm enough to relocated)

But no mosquitoes next year? Priceless…

The gas will be fine for a while, it's non-ethanol and Sta-bil can keep it fresh for up to two years. So I'm not too worried about that, I might have 30 gallons to rotate all at once but the truck can probably take a lot of that when needed.

What I was really hoping for here is some insight into what I can expect with regard to the spiders' life cycle, like do they usually die in the Spring, having protected their eggs over the winter? Or do they live multiple years? And will they just naturally move out of the box when the weather warms up, or do they generally like to stay in one place for their lifetime? How nomadic are they at different parts of the year? I assume these are females, maybe they aren't as nomadic as the males (who I see every fall roaming the house looking to get lucky and trying to avoid the cats)... i.e. What can I expect in terms of being able to have a window of opportunity to access the box without turning anybody's home upside down?

Also, did I get it right in terms of identification? Do these look like Giant House Spiders?
