Outdoor Ant Killers Buying Guide

Almost everyone has had to deal with ants one point in their life.

Unfortunately, the ant problem is frequent, and finding a permanent solution is almost impossible.

Whatever you do, the ants will come back.

Therefore, finding a proper ant killer is almost as impossible as getting rid of the ants.

Our buying guide will sort out the main ant killer types, the advantages, the disadvantages, the performance, the indoor and outdoor use, etc.

Ants usually live outside in our lawn and they are attracted to sugar.

So, they can go inside the house, and that is when killing them may be even harder.

That is because not all indoor formulas are useful.

There are many ant types but the most common people face in their houses or yards is fire ants, Pharaoux ants or Odorous ants.

Some products work for all ant types, but some can be more suitable for one specie.

The effectiveness of the formula can depend on the application type as well.

Therefore, always read the guidelines about the proper application of an ant killer.

ant

The Ant Killer Forms

The products for killing ant come in various form and features different formulas.

Some are bait-based and have slower, but effective performance.

Others can kill on contact, and the best example is a spray.

Choosing the appropriate form depends on your preferences, location of the colony and size of the ant problem.

Let’s have a quick overview of each ant killer option on the market.

Ant Traps

Ant traps are in the form of a small container that holds the ant trap.

The trap can be sugar and water mixed with strong, delayed-release insecticide.

The most convenient ant traps come prefilled with baits, and all you have to do is simply place the bait on the floor or anywhere else you have noticed the ants.

The containers can be clear or colored.

People prefer clear containers because it is easy to see if the ants ate the bait.

Ant traps can be effective in killing the mound because the ant will eat the bait and take it to the mound.

Then, the insecticide will be released, eliminating other ants.

The ant traps are suitable for indoor use.

Also, they are effective because when the Queen dies, other ants will die shortly after.

The disadvantage of the ant traps is that it can attract too many ants.

Therefore, it can cause a larger problem, if the formula isn’t effective.

Also, the ant traps sometimes can require placing several of them around.

Therefore, it can be a costly method of eliminating ants.

Ant Sprays

Ant sprays are another method of killing the ants.

It is a convenient way because of ease of use and killing on the contact method.

The aerosol in the product can either kill or work as a repellant.

Because of the relevant features, sprays can be a more permanent solution.

However, it depends on the formula.

Also, some sprays are toxic for people and pets, so if you plan to use them, you should pay extra attention to placement.

Sprays are an excellent choice for instant reaction and solution.

The best way to use ant spray is to combine it with some other ant killing products, such as ant traps.

The trap will kill the mound and the spray will ensure that ants won’t come back.

You should apply it regularly, following the instruction on the product.

The primary downside of the spray is that it won’t kill the entire colony.

Ant Gels

Ant gels are easy to apply on difficult to reach places, such as cracks or spots.

Usually, the ants come into your home via these cracks, so applying a gel can keep them away.

The gel comes in a tube or a convenient syringe for easier application.

The gel holds concentrated insecticide, which can kill on contact but also spread around to the entire colony.

You can use gel ant killer both inside and outside.

if you wish to use gel, make sure that you identify the type of ants you are having a problem with, to ensure maximum effectiveness.

For example, fire and carpenter ants need different insecticide.

The main advantage of gel is that you can use it to fill the holes and other places, for example, the ceiling.

The gel can be effective for over a month, so it is a convenient way to deal with ants.

The downsides of ant gel are related to drying.

The gel is waterproof when dry, but if you place it outside and it rains, it won’t be effective.

Also, gel sometimes needs two days to dry down.

On the other hand, some gel loses their effectiveness when they get completely dry.

Ant Granules

Ant granules work as a bait to attract the ants, hold the insecticide and take it to the Queen and destroy the entire mound.

You can use granules inside the house, as well as outside with the same performance.

However, some granules need watering for a formula to become active, so they are more for outdoor use.

Also, the poison is effective for a few days.

Granules can be a long-term solution.

Also, the rain won’t mess with the poison, so you can say those are waterproof.

Granules are also excellent solutions for people who have pets because they won’t harm them.

They are safe to use around people and pets and target several ant species.

The cons of using ant granules are related to size.

Granules are larger, and an ant can sometimes avoid them, so they won’t take a bait.

Also, granules can require more effort to work.

For example, you will have to cut the grass, water it properly or use a broadcast spreader to cover the lawn evenly.

lawn

Insect Growth Regulator (IGR)

The IGR contains a substance called Pyriproxyfen (Nylar).

The application is different from others; you should pour it on the mound.

The basic purpose of it is to extinct the entire colony.

However, the performance is slow and can take four months, for the process to be complete.


Conclusion

Finding a permanent solution for ants is a tough challenge.

The ants are a persistent and common problem for many people.

There is several ant killers’ option on the market.

Those are ant traps, gels, sprays, and granules.

When buying an ant killer, first decide whether you will use it indoor or outdoor.

Traps are for example a convenient way to deal with indoor ants, and granules are suitable for outdoor use.

Also, check whether the product kills on contact or has a repealing or delayed effect.

Products that kill on contact are instant responses, but they don’t provide permanent effects.

To ensure a long-lasting effect, make sure that the product can kill an entire mound.
