How to use onions to scare away rats?

You don't need to be a DIY or chemistry expert. Here's a  very simple method  to take advantage of onion's rodent-fighting properties:

What you need:

• Onions (red or white, it doesn't matter)
• A good knife
• A little patience

Steps to follow:

1. Cut the onions into small pieces. The finer they are, the more the aroma diffuses.
2. Place them where you have seen signs of presence: behind furniture, in dark corners, near cracks or pipes.
3. Change them every two to three days to maintain their effectiveness.

Little bonus tip  :  to remember to change them , set a reminder on your phone!

The onion already does a good part of the work, but a few simple reflexes can  amplify  its effect:

• Seal the gaps  : Inspect your home for any gaps. A small hole? A little steel wool or putty, and you're good to go.
• Clean up regularly  : crumbs, opened packets of flour or cat food lying around... it's the perfect buffet for rats! Put everything  in airtight jars .
• Pet Safety  : Onions are  toxic  to dogs and cats. Keep them out of their reach to avoid any problems.

Why prefer onions to chemicals?

It's simple:

• It's economical  : an onion costs less than a euro, whereas store-bought products can quickly add up.
• It's safer  : no substances to handle with gloves, no risks for children.
• It's already in your kitchen  : no need to run to the store or order online.

What if that's not enough?

Let's be honest  : if the infestation is severe, an onion won't be enough to solve everything. If you're hearing noises every night or spotting droppings everywhere, it's best to call a professional. A targeted, reasoned intervention may be the best solution.

How about a simple little gesture for a healthy home?

Sometimes the most effective solutions are also the most natural. With a few well-placed onions and a little vigilance, you could quickly find a  more peaceful ,  rodent-free home . Who would have thought that such an ordinary vegetable could scare away rats?
