Mosquito Dunks – Use Mosquito Dunks For Fungus Gnats?

Mosquito dunks are a great way to control mosquitoes without using harsh chemicals. They’re easy to use and can last for months or even years. Mosquito dunks contain borax which is an effective way to kill and repel mosquitoes, but it can also be harmful if you get it in your eyes or mouth so make sure you follow the instructions carefully if you decide on using them!

What are mosquito dunks?

Mosquito dunks are an insecticide made to combat mosquitoes and their larvae. They can also be used to kill fungus gnats, but they are not a chemical product.

Mosquito dunks work by breaking down into chitin, a molecule that makes up the exoskeleton of arthropods (insects). When ingested by mosquito larvae, the chitin causes them to die from starvation or suffocation as their digestive tracts become full of undigestible material.

It’s important that you don’t confuse mosquito dunks with diatomaceous earth (DE), which is also sometimes referred to as “diatomite” in many countries outside of North America (including Canada). DE is made up of fossilized remains of diatoms and has no relation whatsoever to chitin; however, both products work by killing off mosquito larvae when they come into contact with water containing either substance

What are mosquito dunks made of?

The ingredients of the mosquito dunk include:

  • cornmeal
  • sodium bicarbonate (baking soda)
  • sodium chloride (table salt)
  • sodium carbonate (washing soda), which is not always listed on the package but is present nevertheless. This ingredient also serves as a buffer to keep the pH level from fluctuating too much, thus keeping the bacteria alive longer than other methods of mosquito control. The amount of this ingredient varies depending on where you purchase your mosquito dunks and how long they’ve been sitting around before you bought them.

The rest of the ingredients are just fillers and preservatives to keep your dunks fresh for as long as possible before they become ineffective; however, those preservatives aren’t enough to prevent mold or fungus gnats from invading your home when placed incorrectly in an indoor setting like mine was—if only I’d known then what I know now…

Do they work?

Mosquito dunks are a non-chemical way to control mosquitoes. They work by attracting and killing mosquitoes with the help of Bacillus thuringiensis israelensis (BTI), a naturally occurring soil bacterium that can be effective against mosquitoes in your backyard.

Mosquito dunks are an effective way to control mosquitoes, but they may not be for everyone. This is because these natural alternatives do not kill on contact like some chemical treatments do, meaning you have to wait for them to work their magic over time before you see results. Luckily, there are plenty of other mosquito-reducing products out there that provide instant relief from annoying pests without leaving harmful chemicals behind!

How long do they last?

Mosquito dunks last 6-8 weeks, and it’s recommended that you change them every 3-4 weeks. If you’re using them to control fungus gnats, though, they should be changed more frequently. If you’re using mosquito dunks to control mosquitoes in your yard, they will last longer; however, if you have a large area of grass (like a backyard), then this product might not be the best solution for your problem.

How Control Fungus Gnats Using Mosquito Dunks

Mosquito dunks are made of Bti (bacillus thuringiensis israelensis), a bacteria that kills mosquito larvae. It’s found in soil and can be used as a pesticide to control fungus gnats, although it’s not toxic to humans or pets.

Mosquito Dunks Non-Chemical Solutions

Mosquito dunks are a non-chemical solution to many different types of pests. Mosquito dunks are not a pesticide, and they should not be used as one. However, mosquito dunks will work to get rid of fungus gnats without using any chemicals at all.

The best way to use mosquito dunks is by placing them in standing water where you have seen fungus gnats or other insects gather. The larvae eat the pellets, which kill them off before they can grow into adults that would reproduce (and create more larvae). This process takes roughly two weeks!

Use A Mosquito Dunk

Mosquito dunks are an all-natural solution to killing fungus gnats. They’re safe for you, your family, and pets, but most importantly they work! You can find these products on Amazon or at Walmart for around $5-$7.

You simply place the mosquito dunks in your drains and let them sit for 24 hours before removing them from the drain. The fungus gnats will be dead shortly after exposure to the Dettol crystals that come with each dunk.


Mosquito dunks are a great way to get rid of fungus gnats without using harsh chemicals. They’re also very easy to use and inexpensive, so there really aren’t any downsides! If you have any questions about these little guys or other pests in your home, feel free to leave them in the co
