Many people have to face problems of nuisance pests in the mulch bed as they contain organic compounds that are naturally decomposing into simpler compounds.
How to Get Rid of Ants in Mulch Beds? You can get rid of ants in mulch beds by using red chili powder, making sweet traps, placing cucumber or orange peels, using chemical insecticides, essential oils, or diatomaceous earth.
There are many natural and chemical ways to prevent ants from reaching inside the mulch beds and making their colonies move out of them.
How do you get rid of ants in mulch beds?
It is a time-taking process to remove ants from mulch beds, whether made of organic or inorganic materials, due to the presence of food and shelter.
Spice up the mulch
Ants do not prefer to reach the area where they detect a spicy odor, so it can be used as a deterrent method to keep these annoying insects away from mulch beds.
You can prepare a concentrated essential oil with red chili powder or capsicum to spread on the bed surfaces, making them unappealing for these plant pests.
Hot peppers can also keep ants at a distance from plants because they cannot tolerate sharp, unpleasant, or spicy smells.
Make use of sweet traps
These insects are fond of sweet food as they have a sweet tooth and get attracted to glucose-rich food. I often use sweet food like sugar powder and peanut butter to make ant baits.
Mix 1.5 to 2 tablespoons of sweet food items in 1 tablespoon of a toxic compound like boric acid powder that can make them die within a few hours.
Mix the two dry ingredients in water, honey, or sugar syrup to prepare a thick granular paste. It can be placed inside a bowl or fill straws to capture these insects.
Use cucumber or orange peels
Orange, lemon, or cucumber peels are good deterrents for ants as they have a citrus odor or aqua-green aroma that is not considered pleasant by these insects.
You can prepare a slurry by boiling the peels in the water and preparing a slurry by grinding them well. This slurry can be poured over the garden beds or close to the flower buds to avoid pests.
In addition, you can spread the peels directly on the bed surface to get almost the same results. The aroma of lemon and oranges is quite strong and detected by insects from a distance.
Spread nematodes within the mulch
You can control the population of ants in the garden bed using nematodes, as they are efficient eaters and bring a significant reduction in their number.
However, it is essential to choose only beneficial nematodes that do not interfere with plant growth, as a few plant parasitic nematodes are also present.
Accordingly, Steinernema carpocapsae can be used after getting from a store dealing in chemicals and mixing the paste in water to prepare the spreading paste or liquid.
A garden hose can be helpful in the spread of these biological controlling agents equally on the surface of organic material beds as it brings a noticeable outcome within a few weeks.
Use repelling essential oils
Essential oils are pretty effective in being used as ant-deterrents as insects perceive their strong odors as unpleasant smells.
The odor of peppermint, mint, lemon, and lavender oil can keep these insects away from it prepared from organic matter like leaves and fruit leftovers or peels.
You can spray the oils by mixing a few drops in water; otherwise, prepare cotton balls by soaking them inside the mixture and placing them close to the plants.
Grow lavender or marigold plants
One of the most potential and long-term treatments to prevent the invading insects from reaching the mulch bed is to grow plants with repelling odors.
Lavender and marigold plants are considered to be potent repelling plants and remain effective for a long until the plant dies. Mint, thyme, rosemary, and primrose can also be grown.
These herbs have a soothing aroma and can be used for cooking purposes in addition to keeping the pests away from the plants thriving within them.
Spray soapy solution
A soapy solution can also help get rid of insects within the mulch because it dissolves the outer exoskeleton and makes them drown within the soapy water.
It is a homemade recipe, as you can use dishwashing soap commonly used in the kitchen to prepare a repelling or killing solution.
Moreover, mix 1 to 2 tablespoons of liquid soap into the water and mix it well before pouring it into a spray bottle. Then, shake it 4 to 5 times and spray it directly over the trails to drown tiny insects.
Adding a few drops of oil can improve the results and increases the success rate as a mixture of oil, water, and soap can be poured inside nests to kill them at once as they cannot float on it.
Pour hot water
Boiling water can kill whole colonies of ants thriving within the mulch, as these insects have less tolerance against high temperatures and die immediately.
However, removing pests from the soil is easy, but you have to pour it all over the surface to ensure that the queen does not remain alive.
It is essential to kill the queen, as repelling workers from the soil is a short-term solution. However, a queen can give rise to a new population by laying eggs and fertilizing these eggs with stored sperm.
Pour plenty of hot water to remove the colonies and make your garden beds free of pests.
Use diatomaceous earth
Diatomaceous earth powder works like magic to reduce the population of pests within the soil, as it can efficiently kill insects in a few hours.
It is an effective strategy against insects having a few inches deep nests because the powder cannot reach deep down into the tunnels.
You need to spread the food-grade diatomaceous earth powder on their nests or mainly at the entry points. However, it increases the chances of contact between insects and powder, causing severe dryness.
Accordingly, it removes moisture from their bodies and makes them die due to dehydration or excessive water loss.
Ant controlling insecticides
You can use insecticidal chemicals to remove the ants within mulch if the natural home remedies do not work independently.
These chemicals are harsh on their tiny bodies due to the presence of toxic active ingredients and cause their death immediately within a few minutes to hours.
Why would you get rid of ants in mulch beds?
A few crawling insects on the surface of mulch beds can pose a risk of heavy infestation as they begin to shift colonies after finding a suitable nesting spot.
These insects get nutrition from organic food particles and build deep tunnels within the soil. It results in the quick decomposition of the organic material and requires frequent replacements.
In addition, these can reproduce and multiply in number, affecting the growth rate of plants growing on these beds.
It is better to prevent them from reaching these areas by keeping the bed layer a few inches deep from the curbside because they do not make efforts to reach shallow areas.
Keep these areas away from plants and trees to avoid the risk of damage to fruits and leaves and restrict them from climbing through tree trucks to the rooftop.
So, these insects need to be removed or prevented to keep homes free of pests and improve the soil quality and growth of plants.
What type of ants can affect mulch beds?
A few species of ants get attracted to mulch beds and improve the decomposition process by eating the organic components of the food.
Most commonly, the rover, fire, carpenter, and odorous house ants are supposed to attack these areas after getting attracted to organic compounds and wooden chips if present.
In addition, the black garden and pharaoh ants can also reach there when they find no other food source to meet their nutritional requirements.
