Hey everyone! My wife and I recently bought our first home, and we're getting things sorted out in the basement. We have a French drainage system that leads to a 3x3 hole where our sump pump and battery backup sit. Right now, that hole is open and seems to be contributing to the mold problem we're facing. We've got dehumidifiers in there, which has helped some, but I know we can't just leave this pit open if we want to finish the basement properly.
What's the best way to cover this hole while still keeping it accessible for the pump? I've thought about using wood, but I'm worried it'll just mold. Styrofoam has crossed my mind too... I'm not super handy, but I'm learning.
Also, we're dealing with a lot of crickets and spiders in the basement. Any good pest control tips would be appreciated as well! Thanks in advance!

Using a Plexiglass cover could be a good approach if you can avoid stepping on it. It lets you see what's happening underneath without needing the damn thing wide open. Alternatively, PVC sheeting could work too if you want to DIY a bit.
For those pesky crickets and spiders, I highly recommend using food-grade diatomaceous earth. Just sprinkle it around, but make sure to avoid inhaling the stuff. It works wonders—and maybe just cover that hole temporarily with plywood while you figure things out!
You should consider installing a cover designed specifically for sump pump openings. They have great options out there, like the one from Jackel that allows you to seal up the pit. It's also designed to prevent anything from sneaking in while still letting you access the pump when needed. I've had a similar one for my radon mitigation system and love it—definitely worth checking out!
The best option really depends on your skills and materials. If you're comfortable working with pressure-treated wood, that could work well for you. Some people even make covers with whatever materials they have handy. Just make sure it fits securely! And if you’re still struggling with humidity, maybe look into getting a commercial dehumidifier—they really help out a lot.
I have the Moiswell units, and I can vouch for them! They really do keep our 100-year-old basement fresh.
A clear panel is really useful for visibility too, so you can always keep an eye on what's going on in there!
