Types of Ant Killing Pesticides

Different brands use different methods when making their pesticides and manufacture them in different forms. But it doesn’t mean that one form is inferior to others. The decision which form is suitable for you depends on where you are going to apply the pesticide and the tools available for application. So let’s discuss types of fire ant insecticide in detail.

Ant granules

This form of pesticides utilizes the bait technique to trick the ants to consuming them, hence poisoning them. Due to the social nature of the ants, they will carry the granules back into the mound just like any other food. This works to your advantage because eventually, the queen and larvae will consume them, thereby ending the whole colony. This form of fire ant killer is generally suitable if you are looking for a pesticide to apply outdoors, for example, your lawn, fields, and yards. Granules can remain effective for a long time, even when they come in contact with water.

Ant Sprays

An ant spray is a liquid fire ant killer that usually kills the ant once it comes into contact with it. This makes sprays very effective. Based on how they work, this form of fire ant killer is best used when you want to eliminate ants that have camped in your house. It’s also a good option if you are trying to find a fast solution to eliminate a high population of ants.

Ant gels

These are ant killers that come packed in tubes. The packages are shaped like syringes that make it easier for you to apply them on surfaces. Gels can be a good option for applying on cracks and holes that the ants use to get into your house. They attract ants as bait so you can apply them in areas around your pavements.

Safety Concerns

The process of eliminating ants should not cause more damage than intended. You do not want a situation when you may end up eliminating pets together with the fire ants. Therefore, always look for products that have a minimal negative impact, if any on pets.

Time the Red Ant Killer Needs to Start Working?

How bad is your ant problem, and how fast do you want it to solve? It will depend on the type of fire ant killer you choose to buy. You should read the manufacturer’s instructions on the pesticide to understand how long it takes to experience tangible results.

I hope now you have a clue about how to purchase an effective pesticide. The next step is to understand how to use it to get the expected results. In this section, you’ll find answers to questions that arise on the use of fire ant killers.

How Does Fire Ant Killer Work?

Most of these fire ant killers are poisons that affect the ant nervous system and eventually kill them. For example, granules work by gradually poisoning ants until they are dead.

Unlike sprays, most ant killers are not meant to have an immediate impact. The idea is that the worker ants will take granules and powder to their mound so that even the queen and larvae can consume it. Therefore, it may take hours or even days before you can see the results.

How to Apply Fire Ant Killer?

Begin by establishing where the ant mound is located and their trail. Find their home and determine which paths they use to get there. Once you have established this trail, you should apply the ant bait granules there and wait for the worker ants to take it back to their colony. If the ants have camped inside your house, you can apply the bait outside to attract the ants outdoors. Alternatively, you can directly apply the ant sprays on their mounds. The gel should also be applied near the mound and their paths to have a better impact.

Are Fire Ant Killers Safe Around Vegetables and Pets?

Most of the fire ant killers are poisons. They may have a negative impact on your pet and vegetation around which they are used. Therefore, always read the manufacturer’s instructions to see any potential harm they may have on your pets and vegetables. Always keep the ant killer packages away from your pets.

Already Sure On the Most Effective Fire Ant Killer?

I have given you information and recommendations on how to choose an effective fire ant killer, which I hope will help you make an informed choice. If you ask me, I always give my preference to the Syngenta Advion Insecticide. But it’s up to you to decide which product to buy, and you should take into account your specific circumstances. For example, if you have many pets, you should purchase a pesticide that will not harm them. Also, the situation may be quite different for you if the ants have set camp inside your house.
