5 Types Of Bugs In Litter Box That Make Your Cat Defecate Elsewhere

Bugs in cat litter box

Cats are very hygienic pets. They don’t even like to poop in dirty places. 

They would abandon the litter box if there were a bunch of bugs crawling on the litter.

There are five most common bugs in a cat litter box – fungus gnats, phorid flies, maggots, house flies, and fruit flies.

Now you must be wondering why these bugs get into your cat’s litter box?

It’s because all these bugs breed and infest in damp places that have dead or decaying organic matter. 

So, your cat’s litter box is the best option they’ve got inside your home. 

Later in the post, you’ll find out how they get inside your home. But for now, you should know that these bugs aren’t healthy for you. 

The flies will sit on the litter, and all the dirt and feces stick with their body. And they sit on your food!

Now, that’s something you don’t want to happen. 

Except for maggots, you’ll find most of these bugs as tiny black bugs flying around the cat’s litter box. 

But maggots are the larvae of these bugs. So, that means these bugs live and breed in your cat’s litter box if you don’t get rid of them. 

How To Get Rid Of Bugs In Litter Box?

Get Rid Of Bugs In Litter Box

Thankfully, it is a cakewalk to get rid of bugs in the litter box.

You don’t need any special skills or material to get rid of them. 

The stuff that you need to get rid of them is right there in your home, right now. 

So, here’s what you need to get rid of bugs in the litter box– white vinegar, alcohol, liquid dish soap, water at normal temperature, and a spray bottle.

Here are the steps you can implement right away to eliminate those bugs in your cat’s litter box:

Step#1 – Empty Your Cat’s Litter Box

Begin by emptying the litter box.

A dirty cat litter box is full of cat urine and decaying matter that attract bugs. 

For flies like house flies, and gnats, it’s a heaven.

Also, bugs, especially gnats and house flies will lay eggs in your cat’s litter box. The lay eggs in decaying and filthy matter and the litter box with stale litter is the same.

When the eggs hatch, the larvae of these bugs, which are also known as maggots, come out. These larvae mature and form adult flies.

That worsen the house flies and gnat problem in your home.

Disposing the litter and emptying the litter box will get rid of the larvae and the eggs.

It’s the most crucial step because you’re killing generations of bugs that would have made your home their home.

Step#2 – Disinfect The Litter Box By Washing And Spraying White Vinegar

Now that you’ve emptied the cat’s litter box, it’s time to clean and disinfect it. 

Before disinfecting the litter box, make sure to wear a pair of gloves and a mask. 

You shouldn’t touch the insides of the litter box with bare hands because it’s dirty with decaying cat poop.

And wearing a mask is optional if you can withstand the disgusting stink that comes out of the litter box. 

First, clean it with water and dish soap. Take a dry cloth or sponge and wipe the litter box dry. 

Now mix ten tablespoons of white vinegar with half a gallon of water in equal parts. Stir it well and pour the mixture on a spray bottle. 

Spray the mixture on the litter box. And let the combination sink in the litter box for a while. 

Then wipe the litter box again with a dry sponge or cloth. 

White vinegar is acidic and has anti-pest properties that will kill the germs in the litter box. 

Some people don’t like the smell of white vinegar. If you don’t like it either, you can use alcohol instead of white vinegar to mix with water. 

Alcohol is also a reliable disinfectant

Step#3 – Keep Sticky Fly Traps A Few Feet From The Litter Box

Sticky bug traps and fly traps draw the flying bugs and being sticky, the flying bugs stick with the trap. 

Fly traps are cheap, and they can be a lifesaver especially when the gnats, fruit flies, and drain flies inside the home become a nuisance.

Most of these flies enter homes through open doors and windows. So, keeping fly traps will play a great role in stopping them right at the point of entry.

Outdoors, you can also install bug zappers that will electrocute any flies and mosquitoes trying to sneak inside your home.

Step#4 – Keep A Mixture Of Apple Cider Vinegar And Dish Soap In Your Home

Mixture of apple cider vinegar and dish soap (with a little bit of water) is an effective DIY trap for fungus gnats and house flies.

Mix equal parts of apple cider vinegar and dish soap in a bowl and stir the mixture well. Keep the bowl a few feet away from the litter box, on a shelf.

The smell of apple cider vinegar will attract the bugs and the dish soap will make the bugs stick with it. 

Alternatively, you can also cover the bowl by a cardboard lid with a hole on it. The flying bugs will try to reach the liquid through the hole.

The cardboard lid will trap them.

Step#5 – Keep The Litter Box Away From Windows

All the bugs that you got to know in this post enter through open windows. 

Artificial light from your home attracts bugs like fungus gnats and phorid flies. 

So, don’t keep the litter box near the windows. 

If you do, you’ll increase the chances of bug re-infestation in the litter box. 

Step#6 – Use The Right Type Of Litter In The Litter Box

To keep bugs away from your child’s sandbox you need to use the right type of sand. In the same way using the right litter is crucial in keeping bugs away from the litter box.

You cannot ignore the type of litter in the litter box. There are many types of litters that attract bugs.

Litter made from bio-degradable,  vegetable matter or grain matter like wheat, corn, pine, etc. can draw bugs like cockroaches too.

In contrast, silica-based litter and clay litter don’t draw bugs to them.

However, in most cases, the dirty litter box plays a bigger role in attracting bugs than the litter.

That brings to our final step to get rid of bugs in the litter box.

Step#7 – Refill The Litter Box With Cat Litter

Use the right type of cat litter to refill the litter box. Begin with pouring in less litter.

Then add a layer baking soda. Refill the litter box by pouring in the litter and baking soda alternatively.

Baking soda eliminates the stink from the litter box without irritating your cat. Also, being a desiccant, baking soda also absorbs the excessive moisture in the litter.

It prolongs the life of the litter.

And baking soda is a bug repellent too. It has insecticidal properties that helps the litter box being to remain bug free.

Step#8 – Finally, Scoop Daily

Refill cat litter box

The best solution to have zero bugs in the litter box is to remove the cat poop daily from the litter box. 

The longer the poop stays in the litter box, the more it attracts bugs. 

Source Of Bugs In Litter Box

The source of these bugs in your yard or garden.

Open catch basins, clogged drainpipes, decaying organic waste, and stagnant water are breeding grounds for these bugs. 

And an unclean and ill-managed yard or garden has all of them. 

So, to ensure that you don’t have these bugs flying into your home, here are the steps to follow:

  • Clean your yard or garden of all organic waste.
  • Get rid of bugs in compost bins. 
  • Fill the waterholes in your yard. Waterholes with stagnant water are a breeding ground for mosquitoes.
  • Fix any water leakages in and around your home and yard. Water leakages increase the dampness of your home, and that attracts many bugs. 
  • Use window shields with smaller mesh to prevent flies of all types from entering your home.
  • Keep a bug zapper near windows and doors. 

Remember, there wouldn’t be any bugs in your cat’s litter box if there aren’t any inside your home. 

Why Do You see Maggots In The Litter Box?

Maggots are larvae of flies. If you see maggots in a cat litter box, it means that the flies that laid eggs in the litter box have hatched.

These maggots feed on the organic waste in the litter till they turn adults. 

On top of that, silverfish, weevils, and mites also infest litter boxes if your home has them. 

Maggots can stick to your cat’s body, and your cat can transfer them in different places to your home. 

And once the maggots are all around inside your home, they can attract other bugs like roaches, centipedes, and ants that eat them. 

So, it’d be best if you keep your cat’s litter box free from these bugs.
