How to Keep Spiders Out of the Garage: A Full Guide

OK, you have spiders. By using any of the above-mentioned tools, you can likely get them out of your garage pretty quickly. And now that your garage is cleaned, it is time to keep the spiders out for good. By following not just one, but all of these important tips, you can rest assured with a spiderless garage forever.

Seal Your Boxes!

This is a big one, and not just for spiders. Sealing your boxes properly can also keep out the rats. Rats love nothing more than an unsealed box full of old clothes or stuffed animals. They absolutely love to make their nests there, and you will find yourself with a disgusting spider and rat combo.

Now, to seal your boxes I don’t just mean with clear tape. Don’t just fold your box so it is closed. This does not work to keep out insects or animals. Trust me, I have seen enough garages and storage units in my life to know what most people’s garages look like. Stop with the cardboard boxes and begin using plastic totes that are airtight.

You may need to transfer everything from your cardboard boxes into airtight containers. This is not as difficult as it sounds, and it will be worth it in the long run. Even if you tape your boxes, spiders can still sneak in through tiny holes that eventually wear open, then they can lay lots of eggs. If you must use a cardboard box, wrap that sucker in clear plastic to properly seal it.

Clear Excess Junk

This tip does not apply only to spiders. For peace of mind, I generally suggest everyone keep a tidy garage. If there is junk you are not using, get rid of it. Spiders love junk. They can use it to climb around, make their webs, and just have a general good time. Your junk sprawled all over your garage floor is like a playground for spiders.

Spiders love shady corners because they are sneaky insect predators. Piles of wood, scraps of trash, and old unused tools are a breeding ground for spiders. If you aren’t using it, stop being a hoarder and throw it out. You will have less spiders for sure.

Get Better Lighting

Light attracts insects. If you have a lot of natural light in your garage, chances are pretty good lots of insects will want to get in there. And while this may seem counter intuitive to darken your garage, having less light will actually produce less insects, which means potential spiders will have nothing to feast on.

This is not a huge issue in most garages, as most garages don’t even have windows. But you can still change your light bulbs to be a softer yellow rather than a bright white. Keep the lights off when you’re not in the garage, keep the curtains closed during the daytime, and keep any possible insect food out of your garage. If there’s nothing to eat, the spiders can’t live.

Vacuum & Clean

This is something you will need to do to get rid of the spiders in the first place. This is a little different than removing your unused junk. If you have a lot of space in your garage, there is undoubtedly a lot of dust on the floors, underneath furniture, under the shelves, and everywhere else.

Spiders love laying their eggs in dusty dark places. To stop spiders from spreading, vacuum your garage and get rid of all the dust. Take out the extension hose and suck up all the dust on the shelves, on the top of the shelves, and literally everywhere dust can breed and fester.

By doing this, you will probably end up sucking half the spiders or more out of your garage. This is a critical step in keeping your garage safe from arachnid nightmares.

Seal Your Garage

This is probably the most important step in never having a legion of spiders take over your garage. All possible entrances must be sealed. If there are cracks and crevices where the spiders from outside can sneak into your home garage during the winter and cold months, or even in the summer to try to find a dark and humid place to thrive, they will do it.

The best thing you can do is make sure everything is sealed. For the windows, you want screens that fit tightly and are so well-sealed that not even the smallest mosquito can slip into your garage. Doors and vents should be properly sealed using caulking or spackling paste. And even the cracks in the concrete wall of your garage should be sealed. Spiders can definitely move through walls.

Do the same with your doors. If necessary, get a special strip for underneath your door, thereby stopping spiders from crawling in on the floor. If you have an old ceiling, make sure every possible crevice is fully sealed or spiders will venture into your garage whether you like it or not.

Spider Repellents

A clean garage will keep spiders out. If spiders can’t get in, they will never infest your garage. If there is nothing for spiders to eat, they cannot survive and they will die. However, if you are unable to fully seal your garage, if there are spiders already infesting your stored belongings and the dark corners of your garage, you may need to try repellent.

This can be a more affordable and quicker way to get rid of the immediate spider problem. You can try a home concoction to start with if you don’t feel like going out and buying one of the spider repellents mentioned earlier in the list of products for removing spiders.

Try spraying any essential oil into hot zones where spiders could live in your garage. You can use lavender oil, tea tree oil, or peppermint oil. These are widely available and it only takes a few sprays to repel spiders. Additionally, you may try a mixed solution of coconut oil and vinegar. Spiders hate this!

Spiders also don’t like the smell of cinnamon. As strange as it is, this fact is true. If you are trying to move into your garage in a more relaxed fashion, try lighting cinnamon candles, as the scent will seriously disturb the spiders.

Some other unorthodox tips involve spreading horse chestnuts inside the garage and outside the garage to ward off spiders. Also, you can coat your outlets and other small holes where spiders like to crawl with lemon essence. Don’t think too much about it, just try it!
