Four Reasons Why Ants Are Attracted To Your Bathroom Sink

If you see ants lurking around your bathroom sink, it is really about two things: food and water. Ants need these things to survive, and your bathroom sink could be a good source for both.

So, every time you leave dirt and excess water behind after a shower or brushing, thats a VIP invitation to ants which they would gladly accept.

However, apart from the edible debris and water that you leave behind after a session in the bathroom, Here are other things that might attract ants to your bathroom sink.

The Smell of Your Shower Drain

The scent coming from your drain and sink is attractive to ants because they interpret it as a food and moisture source. Usually, the smell results from dirty plumbing—like sludge in pipes, hair, and other accumulated dirt that has been leftover time and not flushed down the drain.

Remains of Dead Roaches or Other Insects

Ants are opportunistic eaters and will pick up scents of dead insects (including ants) anywhere. So when you have dead roaches or spiders in your bathroom sink, it won’t take long before they follow the insects’ trail to your bathroom sink using any cracked pipes or cervices.

Organic Shampoo or Body Wash

Ants love fruits because they contain sugar, and unfortunately, most organic shampoo and body wash has a fruity-like smell. So you can trust it will be hard for ants to ignore your bathroom sink if you have organic shampoo or body wash.

Fermented Hair and Skin Cells

When you brush your teeth and comb your hair by the bathroom sink, part of your hair and skin tends to fall off and enter the sink. Over time, they accumulate and start to ferment, leading to fungus and mold growth. The fermenting smell attracts ants, and they will try to find their way to it.

Other things that attract ants to your bathroom sink are their search for warmth, other edible materials (if you are one to take a snack in the bathroom), and faulty plumbing.

So what do you do about these little pests before they begin a disturbing party that gets out of hand?
