What Is the Need for An Ant Killer?

Ants are very persistent. Once your home is infested by ants then it becomes difficult to control them. Outdoor ants come into your home either to look for food & water or because of the change in weather. Outside ants enter the household area through small openings and leave trails behind so that their colony can follow. Ants are tiny creatures, but their invasion can cause a lot of havoc on your homes.​

Ants can contaminate food and water, which can result in the spreading of diseases. Ant bites and stings can cause allergic reactions in humans as well as pets. Ant colonies are difficult to dislodge but not impossible. With proper vigilance and the right product, ant colonies can be killed in a week or two. Outdoor ant colonies should always be kept under control so that they do not move inside.

A Short Brief on The Types Of Ants

Carpenter Ants

Carpenter Ants

Carpenter Ants

These ants prefer staying outdoors and they get their name from their nest building technique. They do not eat wood, instead they build small tunnels inside the wood. Carpenter ants love water, hence you will find them around moisture stricken areas. This colony of ants can be recognized from their large size. If you have a carpenter ant infestation in your home, then it is important to act quickly as they are known for destruction which can’t be taken care of by ant killers.

Fire Ants

Fire Ants

These ants are red tiny pests who favor sunny conditions. Fire ants can be a cause of allergic reactions to house owners and their pets. Infestation from this colony of ants can turn out to be a nightmare. They build their nests deep below the ground without a central entrance. Just like carpenter ants, these ants also need to be killed as soon as you spot them.

How to Choose the Right Outside Ant Killer Product?

Just like other animals, ants are also an important part of the ecosystem. Unfortunately, ant infestations in your yard and home can turn out to be a big issue. Choosing the right ant killer can make a huge difference in the protection of your surroundings. The best outdoor ant killers use a bait, containing a slow-acting insecticide. Let’s look at some of the types of outdoor ant killer products.

Liquid Baits - Liquids & Gels

Liquid baits use sweet solutions as their baits. Gel baits are given with syringes and are used for hard to reach traps.

Solid Baits - Dust & Grains

Solid baits consist of protein types of baits that are spread out over a lawn. These are used to dry out the exoskeletons of outside ants found in the yard or lawn. For eg., Diatomaceous earth soil.

Sprays

Aerosols and liquid sprays act as a deterrent for outside ants. You should opt for this product depending on the ants present in your lawn.

The product that you are choosing to kill the ants should be weatherproof. If you are staying in a rain prone zone, then you should go for waterproof products which must not get washed away by rain. If you are looking for a cost-effective solution to wipe out the ants from your yard, then look for a product that combines protein baits with and sweet baits together. If you notice that the ants are coming inside your house through the tiny crevices in your walls then avoid buying granules.

For a short-term solution, you can choose ant sprays. If you notice ants lingering in your yard, even after continuous usage of the sprays then you should opt for baits.

Also, you should make sure that the product should be child and pet-friendly. 

The Negative Effect of Ant Killers on Environment

Ant killing products are used to destroy, repel or kill ants. These products are used to ensure safety and protection from ants, but they can prove to be quite fatal for the environment and human health. The pesticides used to kill ants might destroy the quality of soil in your lawn. Pesticides remove a huge amount of organic matter from the soil and make it less fertile. When you spray an ant killing product in your lawn, the product is sucked into groundwater. This will, later on, pass into the nearest water body. The product sprayed in your yard might also get drifted through winds and pollute the air.

The acute effects of pesticides on the health of humans can cause stinging eyes, rashes, blisters, blindness, nausea, dizziness & diarrhea, and the chronic effects can be cancer, birth defects, and neurological toxicity.
