Why Does the Air Outside Smell Like Fish? Reasons And How to Get Rid of the Smell

You may have noticed a fishy smell in the air and wondered what could be causing it. There are a few reasons why the air might smell like fish, and most of them are not very pleasant. The fishy smell could be caused by something as simple as someone cooking fish nearby, or it could be indicative of a more serious problem, such as a natural gas leak.

In this article, we will discuss some of the possible causes of a fishy smell in the air and offer some tips on how to get rid of it.

What does it mean when you smell fish in the air?

When you smell fish in the air, it is usually an indication of an electrical problem. The fishy odor can be caused by worn-out wires, a weak breaker box, condensate drain lines, or mold. Electrical issues can lead to serious safety hazards such as fires or electrocution. Additionally, spoiled food can also cause a similar odor which should be disposed of properly to avoid health risks such as food poisoning or salmonella infections

Here’s Why the air outside smells like fish

Pythium fungus

Pythium fungus is a type of fungal infection that causes brown rot in the grass. It attacks the roots, stems, and cortex of the plant, progressing up the stem. It thrives on warm nights with temperatures between 68-86 degrees Fahrenheit and in wet or waterlogged soil conditions.

The presence of Pythium fungus leads to stunted growth, circular patches during warm humid conditions, yellowing of lower leaves on the grass plant, and eventually death if left untreated. The circular spots appear water-soaked in the mornings due to poor drainage that results in insufficient oxygen supply.

Additionally, a fishy odor is produced due to rotting grass stems combined with decaying root tips – this can be detected when rubbing between fingers. Fungicides can be used to suppress this problem but must be applied before the grass dies otherwise they will not work effectively (contact & systemic types available).

The Presence of Bradford pears in your yard

The Bradford pear is a tree with a fairly white appearance, a weak branching structure, and thick limbs that overshadow a lawn. Its flowers during the springtime give off a fishy odor that is unpleasant. The presence of the tree in your lawn or vicinity could be the source of this smell due to excess moisture retention in the area.

A lawn area shaded by Bradford pears is prone to fungi infection due to excess moisture retention which can lead to an increased smell of fish. Additionally, standing water near these trees can also contribute to an unpleasant odor as it decomposes over time.

Compost bins can cause fishy-smelling grass

The fishy smell in the grass can be caused by the presence of Pythium fungus, which leads to root rot and stickiness. This can cause the grass to become sticky, leading to foul odors that can be difficult to get rid of. Additionally, it may also lead to poor lawn health if left untreated.

How can I get rid of the fishy smell outside?

Use Fungicides

Apply a contact fungicide such as plant health fungus control or signature stressgard to the affected area of the lawn. Spray it on the lawn and also on the soil for best results.

Apply a systemic fungicide such as Balan fungicide for maximum protection against Pythium fungi and turf diseases resulting from both biotic and abiotic sources.

Follow these tips for prevention or avoidance of fungal infection: collect and toss grass clippings, keep your grass adequately fertilized and watered, ensure mower blades are sharp and clean, keep your grass 2 to 2 ½ inches long, fill up depressions in the lawn that may contain moisture or create shade spots perfect for fungi growth.

Plant scented plants in your yard

Plant scented plants such as Hyacinth, Magnolia, Gardenia, Wisteria, Sweet Alyssum, Honeysuckle, Roses, Phlox butterfly bush, and flowering crabapple in your yard.

The breeze will spread the scent of these plants around your landscape improving its fragrance and beauty. The scented plants will help get rid of the fishy smell outside by masking it with their own fragrances. You can also add mulch to further reduce any odor from seeping into the ground

Always empty the trash and get rid of rotten fish around your neighborhood

The air outside can smell like fish for many reasons. One reason might be that there is a lot of trash and rotting fish around your neighborhood. Always empty the trash and get rid of rotten fish to help reduce the fishy smell outside.

Tips on how to get rid of fishy odors in the air

Get rid of flowers that smell like fish in your yard

If you have a fishy smell in your yard, it’s likely coming from flowers that smell like fish. To get rid of the odor, remove any flowers that smell like fish and dispose of them properly. You can also try planting other flowers that have a strong scent, such as roses or lilies, to help mask the fishy smell.

Fix any electrical issues in the yard

Walk around your house and check all the outlets and lights to make sure they are properly connected. If you find one that is not connected properly, do not plug it back in; instead, carefully remove it and call an electrician.

If you have a bad wire in an appliance, you can fix it by turning off the device/tool, disconnecting the wires, clipping off the burned-out part from both sides, reconnecting the “healthy” parts of the wire with heat shrink tubing, and securing them with a soldering tool if available (requires expertise).

Get rid of Plants like Bradford pear flowers

Remove the Bradford pear trees from your lawn or vicinity. This will prevent the excess moisture retention that contributes to the fishy smell. Plant alternative types of trees, such as Crapemyrtles, instead of Bradford pears (American hornbeam, Serviceberry, fringe tree, Pagoda dogwood, and yellowwood).

Water your lawn regularly to help keep it healthy and reduce any unwanted odors caused by fungi growth due to excessive moisture retention under the shade of the tree’s branches.

Use an air purifier or fan if necessary to help remove any lingering smells from indoors or out in your yard area around these flowering trees during their bloom period this spring season

Always dispose of your garbage bags

It is important to dispose of garbage bags regularly to ensure that they do not become a source of odor or attract insects and other pests. Once a garbage bag has reached its capacity, it should be properly sealed and disposed of in order to avoid any potential health risks. Additionally, it is important to follow local guidelines on how often bags should be replaced or taken out for disposal. This will help ensure that waste management services remain efficient and effective.


What is the cause of the fishy smell in my air ducts?

The fishy smell in your air ducts may be caused by mold growth inside the ductwork. This may be due to the warm, dark, and moist environment of the vent system.

If an AC unit has grown a layer of mold inside its ductwork, the smell may be stronger near air vents than near outlets or light fixtures. An HVAC specialist can inspect your ductwork and clean it if necessary to remove any mold and eliminate any harmful toxins it may have produced. Additionally, installing a dehumidifying system or UV lights in the ductwork can help prevent future mold growth in your AC unit.

When it rains, the ground and plants release oils into the soil which blend with other earthy odors. These odors are released into the air when the relative humidity at a ground level exceeds 75%, resulting in a fishy/wet doggy smell.
