DIY Ant Sprays And Home Remedies

In this section, we come up with a few methods for making the best ant killer spray for indoors that is suitable for most ant species. These are simple remedies you can try out if your ant problem is not very significant. Natural indoor ant sprays can also work wonders to act as an ant deterrent and keep them away from your home. Additionally, these are DIY pest check methods for indoor and outdoor use.

We all know that where there is one ant, there are more ants in waiting. Therefore, getting ahead of the situation is not a challenging task. The sooner, the better before all the worker ants swarm your house to find food. Wiping out ant trails should also be a priority because they act like a well-paved road to any foodstuff. Here is the perfect list of the best ant killer spray for indoors.

a) Peppermint Essential Oil

Peppermint oil is an effective method to get rid of ants. It is also perfect for indoor use. Other essential oils also work well to kill ants. Peppermint is a strong-smelling essential oil that is also a natural remedy. Furthermore, it works by erasing ant trails which deters ants from coming into your home. It is suitable for outdoor use and anthills. Getting peppermint is easy because it is sold in most stores.

It works perfectly as a spray. To mix it, you should mix up to 20 drops of peppermint solution in two cups of water and shake well to mix. You can spray at any point where even black ants use as an entry to come into your house. Allow the peppermint mixture to dry.

b) Diatomaceous Earth

For clarification, diatomaceous earth isn’t a poison. It consists mainly of fossilized remains of aquatic organisms called diatoms. When you apply this organic substance to any ants crawling in your home, it dries their skeleton out. You can use this clever method to put a stop to a whole colony of ants. You can also utilize it both indoors and in any outdoor ant category. You should also make sure to remove any food sources where the ants might be feeding.

Using diatomaceous earth isn’t tricky because after purchasing it, you can sprinkle it straight from the packet. It is similar in texture to granular ant bait, except it absorbs all the oil from the skeletons of the ants. Ants have an exoskeleton, so they do not have to ingest any diatomaceous earth for it to be suitable for indoor use. Be super careful not to inhale this ingredient because it is an irritant.

c) Dish Soap

Using dish detergent is another simple way of removing ants or even an entire colony from your home. It is super stressful when some ants don’t immediately take to bait stations, as we have seen with some liquid ant baits. However, using dish detergent works just as well as chemical ant killers. The active ingredient in soap is triclosan, which also discourages ants. You can also mix it in with other ingredients such as lemon juice.

In a spray bottle, mix equal parts of dish detergent, lemon juice, and water. Shake well until it is soapy. You can then spray the mixture all over the area where ants frequently pass by. This can be on windows, under doors, and in corners around the house. Using soapy water wipes off any pheromone trails where there is a possibility that any outdoor ant family will come into the house.

d) Vinegar Mixture

Any ant problem is annoying. Especially when they are all over. A few sightings should be stopped before it leads to more ants and an infestation. Unlike liquid bait, ants will not eat vinegar. However, they hate the smell of vinegar. The dominant ingredient in vinegar is ethanoic acid. This acid is super solid and effective as the best ant killer spray for indoors. It works as a strong deterrent for ants, and it is super-efficient.

To prepare the mixture, mix equal parts of water and white vinegar and shake well. You can also probably mix in a few drops of tea tree oil for a better smell. However, the smell of vinegar will repel most insects and even Argentine ants. You can use this mixture throughout your house, including on hard surfaces like floors and countertops. For the outdoors, you can pour the mixture in mounds over the entire colony.

e) Boiling water

This method works on contact. It involves bringing a pot of tap water to a boil and using it immediately. However, boiling water is dangerous. So you have to be super diligent with safety when using it. But, unlike ant bait, it works immediately. If your ant problem is significant, bring water to a boil, and then pour it over any visible mounds. This will kill an entire colony. Not much can survive hot water.

For ants that are already indoors, you can scoop hot water carefully and pour it on them. They will not stand a chance. This method is super helpful, especially if you need a method to work immediately. However, if you use hot water indoors, you might need to clean up after. Pouring water might make a mess, so be ready with a mop to clean up any spills. Ensure you have a professional provide medical advice incase of burns.

How do you choose the best Ant killer spray? (Buying Guide)

Things to consider when you are buying an Ant killer spray: There is a long list of these creatures, but today we will talk about the ANTS. Because every household insect has their season to come out in troops, and we know that spring is arriving, and this is the high time when ants show up in your home.

What Brings Ants To Your House?

When you suddenly get ants, you might be baffled as to where they are coming from and why. There are a few reasons why ants flock to your home. First, you should know that ants are always going somewhere, and they have come from somewhere. On a bit of an interesting ant fact, ants are very successful in their pursuit of food. Ten out of ten times, ants love you for your food. So what reasons do ants have for coming to your house?

i) Food

The number one motivator for most species is food. That applies to tiny ants as well. Ants are expert foragers and gatherers. Ants also live long. Therefore, when you get an ant infestation, they are primarily after food. They prefer sweet and sugary foods. When you leave a small juice spill on your counter, ants are probably going to be there in a few minutes. Therefore, being vigilant with wiping spills on surfaces is super important.

Additionally, storing food well should be a number one priority in your kitchen. Using a homemade best ant killer spray will do you good for prevention. All foods, even fruits, should be stored well in the fridge. You also shouldn’t leave any food open overnight.

ii) Nesting

Ants breed very quickly. The queen ant should live for up to 30 years, and her primary job is to lay eggs. Therefore, when ants find a food source, they leave a trail of hormones to alert the rest of the colony. This is a very efficient form of communication. Within minutes, more ants are there. Every ant will carry back crumbs of food to the nest. This serves as food for the baby ants and ant queen when they are nesting.

Foraging plays an essential part in sustaining the ever-growing ant colony. Therefore, if you find ants in your home, they might also be nesting. Food has to constantly be there, hence why ants are very hard to get rid of.

ii) Seasons

You might have noticed a few ants sluggishly walking in your house during winter. This might mean that there is an ant colony close by. Ants hibernate during winter and live off some of the food that they forage when it’s warmer. However, during winter, they will also venture out to try and find more food especially, if they have a nest near a house with food.

Therefore, they usually go away on their own during this time because they are in active hibernation. Therefore, if you take away any source of food, they will be gone in a few hours. You can also set up ant bait in bait stations if you are unable to wait.

Final Verdict

To wrap it up, we can say ant killer sprays are not for long-lasting use like bait, powders, or gels, but they are very instant killers. Because you don’t have to wait until ants come in touch with them, just spray and kill the insects as needed. The listed sprays are very efficient and user-friendly. I hope they will help prevent the annoying situation you face because of the ants. Furthermore, they also avoid different bugs and pests so that you can have tension-free preservation in your household areas and garden.
