How to get rid of grubs in the home?

House grubs are the larvae of diptera, often found in the home.

Although completely harmless, these maggots are insects in the making that you don’t want in your home. What’s more, they’re not exactly pretty to look at.

So here’s how to get rid of them for good.

What is a white grub?

A white grub, also known as a maggot, is the larva of a fly or food moth. These small, often slimy white worms have no legs or distinct head, but do have a pair of hooks for feeding. Generally measuring between 4 mm and 1.2 cm in length, they thrive rapidly in damp areas and decomposing matter. Their presence in the home can be particularly unpleasant, especially when they appear in large numbers.

Why are there grubs in the home?

White grubs often appear in inaccessible corners of the home, such as drains, dustbins and damp areas. Organic deposits, such as food scraps and excrement, are an ideal food source for these larvae. Flies lay their eggs in these places, and the temperature and humidity conditions in the home favor their hatching into grubs. So it’s crucial to keep an eye on these areas to avoid infestation.

How can I prevent the appearance of grubs in my home?

To avoid the appearance of grubs, it’s essential to maintain rigorous hygiene in the home. Here are a few practical tips:

Regularly clean surfaces and damp areas.
Use watertight garbage bags to prevent organic waste from leaking out.
Separate organic waste from other types of waste.
Check drains and garbage cans frequently for grubs.

By following these simple steps, you’ll greatly reduce the risk of grubs appearing in your home.

Methods for eliminating grubs

If, despite all your precautions, grubs do appear, here are a few effective ways to get rid of them:

Use diluted bleach to kill grubs and flies.
Clean surfaces and damp areas with boiling water and detergent.
Install fly traps to catch adult flies before they lay their eggs.
Place repellent plants, such as lavender, to keep flies away from your home.

These methods will help you get rid of grubs and prevent their reappearance.

How do I clean grub-infested surfaces?

To effectively clean grub-infested surfaces, follow these steps:

Remove all food waste and residues.
Clean surfaces with boiling water and detergent.
Rinse thoroughly to remove all detergent residues.
Dry surfaces thoroughly to prevent grubs from reappearing.

By following these steps, you can be sure of ridding your home of grubs and preventing future infestations. Prevention remains the best way to avoid these inconveniences, so don’t hesitate to adopt these good practices on a daily basis.

Why are there grubs in the home?

White grubs are most often found in the kitchen, on the floor, sometimes on the ceiling, and sometimes even in the garbage.

Contrary to popular belief, these bugs are not the result of poor hygiene, but rather of clogged pipes. Organic deposits, such as food scraps, excrement and other organic matter, are an ideal food source for these larvae.

Most often, grubs are fly larvae or food moth larvae. The latter are quite opportunistic, depositing their eggs as soon as an opportunity arises.

It takes about half a day after laying for an egg to develop into a larva. The grub then feeds on its surroundings, transforming into an adult fly or moth.

How can I prevent white grubs from appearing in my home?

There are several simple steps you can take to prevent grubs from developing in your home. Here are just a few:

Avoid leaving food out in the open on the kitchen counter.
Wash drains occasionally with diluted bleach.
Wash worktops, gas stoves, windows and cupboards with pure white vinegar.
Always throw away leftovers after you’ve finished eating.
Make sure that the garbage can is always clean and properly closed (kitchen, bathroom).
If food has gone mouldy or is decomposing, always remember to seal it in a plastic bag and throw it in the garbage can, so that the little maggots don’t quickly appear in the garbage can.

You can also use a number of natural, chemical-free repellent methods to get rid of flies and food moths and prevent them from laying their larvae in your home:

By using the properties and fragrance of lavender, in bouquets around the house, dried like grandma’s potpourri or in the form of an essential oil. Flies loathe lavender, and you can use it to diffuse a wonderful fragrance throughout the house.
Using the properties of garlic. Simply boil peeled cloves and filter the liquid. Once the solution has cooled, it can be sprayed on all windowsills to keep flies out.
Using the properties of cloves, whose scent is much less appreciated by flies. To implement this trick, simply prick the citrus fruit of your choice (lemon, orange, etc.) with several cloves and store them in strategic places around the house to avoid their presence.

How do I clean grub-infested surfaces?

When small white grubs have taken up residence in a house, there can sometimes be dozens of them grouped together in the same place (wet or dry areas).

In this case, you mustn’t panic in the face of this unpleasant appearance, and proceed with a thorough cleaning of the space, taking into account the material of the support so as not to damage it (work surface, tablecloth…). This is particularly the case with carpets and rugs, where worms may have lodged.

Here’s how to clean carpets and remove grubs:

Use a dustpan to remove as many maggots as possible from the carpet, then empty the contents of the dustpan into an airtight bag.
A simple trick is to put the bag in the freezer so that the cold kills the maggots. While this technique may be repugnant to some, the bag can be disposed of directly in the trash.
Next, sprinkle pure Borax (boric acid) directly onto the carpet and leave for a few minutes.
Vacuum and empty the contents of the dust compartment into an airtight bag for disposal in the garbage can, or leave in the freezer for half an hour if you’re feeling brave.
Finally, we recommend spraying the carpet or rug with a textile disinfectant or using a steam cleaner, repeating the operation 2 times.

After such a cleaning operation, you can be sure that no traces of insect larvae or eggs remain in the textile. Above all, flies are no longer likely to return to lay their eggs.

The case of the dustbin

Because it contains so much food and is so damp, the kitchen garbage can is a favorite place for flies and food moths to lay their eggs.

Here’s how to get rid of grubs in the garbage can and prevent dozens of flies from scattering around the house after hatching.

After removing the bag, give the garbage can a thorough cleaning with soapy water.
Next, boil a sufficient quantity of water and pour the boiling water into the garbage can.
Then empty the contents into the sink.
Give the garbage can a good cleaning with soapy water, scrubbing all sides and bottom with a brush.
Leave the garbage can to dry in the sun if possible.
Finally, add a few drops of mint or lavender essential oil, known to repel larvae, maggots and flies.

For greater effectiveness against grubs, we recommend you carry out this type of cleaning approximately every two weeks. For this treatment to be effective, it’s equally important to clean the kitchen garbage can and the outside garbage cans.

A final tip to prevent grubs from developing inside your garbage cans: remember to secure the garbage can liner with a rubber band. This will prevent food from accidentally falling to the bottom of the garbage can and rotting there, which would lead to the development of new maggots. You can get rid of the white worm or maggot by applying these simple measures.
