You’ve come to the right place if you are constantly finding pests inside your outbuildings. Spiders in the shed? Bugs in the greenhouse? Not for long! Here is everything you need to know about how to prevent pests from entering your shed or greenhouse.

How to keep spiders out of your shed

If you see a spider in your shed during the day, odds are that it’s not going to be a dangerous one. The risk comes when you have dark, hidden corners, empty boxes and the like. Because here, dangerous spiders who prefer the darkness like to lurk.

Unfortunately, your shed can be a major source of dark corners and hidden spaces. This means a little spider proofing can go a long way to deter spiders from entering.

How to make a spider-proof shed

Figuring out how to keep spiders out of your shed takes a little bit of planning and some materials:

  1. Seal entrance points – Those spiders are getting in from somewhere. Check your shed door, windows, walls and roof for any holes or cracks they could be entering through. Fit weatherstrips to the door and use caulk to seal any holes. If you regularly leave the window open, get a screen.
  2. Have a clear out – Is your shed a little untidy? That mess will make it all the more difficult to manage the problem, as well as give your unwanted guests more places to hide. Declutter your shed and remove any empty containers. Then, vacuum your shed in case there are any eggs, hidden spiders or insects that might seem like a good spider meal.
  3. Check before you store stuff away – Always check for eight-legged hitchhikers before returning tools to your shed.
  4. Store smart – Seal empty containers and store them with space between them and the walls to make it more difficult for spiders to hide.
  5. Change your bulbs – Got lights around your shed? And regularly see insects around them? They’re the perfect bait for spiders. Replace your bulbs with sodium vapour or yellow bulbs to keep spiders out of your shed.

Keep wasps out of your shed the safe way

First thing’s first. If what you have is a hornet problem, you need professional pest removal experts to take care of it. Hornets are much larger than wasps, so you should be able to identify them easily.

When you want to keep wasps out of your shed, try:

  1. Wasp proofing – Use caulk to seal any holes or cracks that might allow wasps to enter. Consider hanging mesh or wire screening across the possible nest sites like overhangs.
  2. Remove food sources – Fallen fruit, BBQ remnants or sugary drinks that have been left unattended attract wasps that can, then sneak into your shed. So, be sure to get rid of any food sources fast after you’re done with it to deny wasps the sweet things they love. Keep your lawn clear of rotting fruit, as well.
  3. Eliminate the pheromones – Wasps usually only use the same nest for one year. Once they’re gone, remove the nest as it signals to other wasps that this is a great place to live via pheromones the previous occupants leave behind. After you’ve removed the nest, give the area a proper scrub with soapy water to eliminate the pheromones.
  4. Get rid of ground holes and piles of wood – If you leave piles of logs or debris around, you are asking for wasps to move in. Some species also like living in holes in the ground, so cover them up when you find them.
  5. Try artificial prevention or natural protection – You can buy wasp traps and even fake nests to deal with the problem. Also, wasps hate strong scents. Plants that keep spiders away like lemongrass and spearmint also do a great job of putting off wasps. You might also try eucalyptus, citronella or thyme. Mothballs also work for the same reason.

How to keep mice out of your shed

Actually, removing mice from your shed once they are in there can be a hard-to-do and unpleasant task. They don’t fall easily for traps and baits, either, meaning it’s usually best to call in an expert.

Keep mice out of your shed with simple solutions

As far as keeping mice out of your shed goes, some of the measures listed above – filling holes and gaps, removing food sources and giving your shed a good clean – all still apply. You might also try:

  1. Bleach – Wash your shed with water and bleach to eliminate the smell of previous mice, which can attract more. Plus, mice hate the strong odour of bleach.
  2. Use natural scents – Peppermint and chilli oil, mothballs, cloves and cayenne pepper, all repel mice. You can also put some used cat litter in a corner. It doesn’t sound too pleasant, but it’s positively threatening to the mice which won’t enter for fear of a cat.
  3. Get a cat (or attract an owl) – Not to be considered lightly, getting a pet cat can be a solution to a mouse problem. A pet cat is a responsibility, though – not just a solution to the problem of how to keep mice out of your shed. Equally, you can put up an owl house to try and attract an owl to your garden. Of course, this mice-deterrent method isn’t guaranteed and may not suit you.

Animals that live under sheds – the signs

If you’re concerned that you are dealing with one of the many types of animals that live under sheds, there are a few signs to watch out for.

Actually seeing them is the first and most obvious one. Motion sensor cameras can help you spot nighttime visitors, too. Another common sight is damage like gnawed wood, vegetables that have been snacked on or holes in the ground.

You might also be able to spot paw prints, droppings and other signs of unwanted animals’ presence. Try dusting a little sand around the area if you want to make spotting tracks easier.

How to keep animals out from under your shed

When it comes to how to keep animals out from under your shed, there are a few ways to go about it. Trap and release methods rarely deliver good results for you or the animal in question. If you want to humanely remove animals living under your shed, call in a professional. Or you can try:

  1. Making some noise – Leave a radio playing under your shed or find some other way of generating noise that stops that place sounding so inviting to visitors!
  2. Using some light – Similarly, that dark sheltered place will look less appealing if you can get some strobing or flashing light in there.
  3. Utilising the power of smells – Apple cider vinegar and other strong-smelling solutions can drive off pests. Try to spot the kind of pest you are dealing with to make sure you can find something they don’t like.

On top of these humane removal and repellent methods, you can keep other animals out from under your shed by answering some basic questions about how it is constructed.

How high should a shed be off the ground?

It’s generally suggested that a shed should be at least 4 inches (10 cm) off the ground to allow air to circulate. If you live in an area with soft soil or heavy rainfall, you might want to up this slightly. But you don’t want to raise it by too much more as this can lead to instability.

Unfortunately, this is the ideal height for some animals to find the space under the shed appealing.

How to fill gaps in a wooden shed

Filling up entry points in sheds is the best way to keep any pests out. Here’s how to fill gaps in a wooden shed if needed:

  • Keep insects out – The task can usually be accomplished with wood sealant, caulk or expandable foam. Another option is placing rubber strips or weather strips.
  • Keep mice out – Mice can usually chew through rubber strips. Some people suggest putting down an extra layer of plywood to keep them out.

How to get animals out of walls
