Top 9 Ant Killer for your Home and Garden

Top 9 Ant Killer for your Home and Garden

Ants are fascinating social creatures which mean they live in large colonies or group. There are approximately 12,000 species of ants around the world and they play a significant role in the ecosystem. However, not all species of ants are nice to be kept around your garden nor inside your home.

Most ants live outdoors, but sometimes they make their way inside your home looking for food and water sources. They mark their trails using scent chemicals that guide other ants from their colony to a good supply source, often invading your kitchen cabinet, pantry shelves, pet food bowls, or garbage pail. Some ants can be a real nuisance to your garden as well as they can destroy the natural growth of your plants.

What is Ant Killers?

Ant killers are chemically formulated products to keep ants at bay and protect your Garden as well as your home from ant invasion. Some of ant killers are designed to act as a potent fertilizer for your lawn.

Although there’s have to be some benefits of having a healthy ant ecosystem in your backyard, some will find them troublesome and may actually cause more harm than good.

  1. Damage your plants – A healthy plant is all that any green thumb can ask for. However, no matter how good you are at keeping your plants happy and taken care of nature can be quite daunting and may require human intervention. Ants like to build their nests around the root of plants, which can stunt their growth and leave plants more vulnerable to diseases. They can eat away the leaves of your plants, leaving your plants defenceless and unable to make their own food.
  2. Cause injury -Some ants have stingers that are entirely different from a typical ant bite. Fire ants, for example, inject venom with their stinger. This sting is painful and may cause serious issues that are not only uncomfortable but even life-threatening in some cases. Although small, ant bites leave toxic chemicals on their bite sites. This poses a threat to children under the age of 5 since they haven’t built sufficient immunity yet and may cause a severe allergic reaction.
  3. Attract another pest – As the rule of nature, all living things have their own prey and predators. This goes the same with ants. Other harmful bugs and insects can be attracted to the growing ant population in your backyard and can ruin your garden. A few species of ant eat honeydew, which is excreted by aphids as they feast on plants. Ants protect aphids from other predators. Increased aphid activity in your garden is terrible for your plants as they suck out all tasty plant sap causing it to wilt.
  4. Damage your home – Carpenter ants are similar to termites, but they do not eat wood. Instead, they tunnel and chew through wood to create nests that can threaten the structural stability of your home.

Here is the list of the best ant killer we recommend for you:
