Mosquito Dunks vs Mosquito Bits (What’s the Difference? Which is Better?)

Thankfully, there are two ingenious products to deal with this: mosquito dunk and mosquito bits. In this article, we take a look at the difference between mosquito dunks and mosquito bits and which is better in what situation to help get rid of and prevent mosquito infestation.

Difference Between Mosquito Dunks and Mosquito Bits

Essentially, both mosquito dunks and mosquito bits are made from the same active ingredient called Bacillus Thuringiensis Israelensis (Bti), which is effective in controlling and killing mosquito larvae. They are also relatively safe to use around humans, pets, and plants and hence do not cause any harm to the environment when used outdoors.

The main difference between mosquito dunks and bits is their shape and size. A mosquito dunk has the shape of a small donut and is bigger in size as compared to the mosquito bit. And because of its size difference, it usually contains more active ingredients than mosquito bits. A single mosquito dunk can be used in a large body of water like a large water fountain or artificial pond. You can also break a single dunk into small pieces for smaller sized ponds.

On the other hand, mosquito bits are smaller and look like small pellets. Because of their size and the fact that there are more surface areas that touch the water when in contact, mosquito bits release the active ingredient faster and can be used in areas with patches of water, like the shallow parts of the pond, in the field near water catchment areas.

How to Apply Mosquito Dunks and Mosquito Bits

To use the mosquito dunk or mosquito bit products, simply remove them from their packaging and toss them in the water you want to treat.

Most mosquito dunks can last for about 30 days in water. These are great for larger water bodies that usually have water permanently that could host and allow mosquito breeding like a swamp, a pond, or a water feature in your garden. 

Mosquito bits dissolve much quicker, usually around 24 – 30 hours. Due to the small size of mosquito bits, they are ideal for smaller water features like a birdbath, fountain, field or puddle.

Some great examples are dry catchment areas outside where you know you will likely catch water when it rains, for example unused tyres outside the garage, empty containers, plant pots that you know does filter water out properly, large/deep grass patches in the garden etc. [May: Or if you know that you will be heading out of the house for quite awhile and expect a certain area to catch water when you’re gone.]

Mosquito Dunks and Bits are Effective Against Fungus Gnat too

Most mosquito dunks and bits are also effective in controlling fungus gnats. These are very small pests that fly around, breeding in water and moist soil. To apply, mix dunk/bits with water and spray the mixture to your plants or pour treated water into soil where fungus gnats grow.
