Ant Killer Buying Guide

One thing about us humans is that we hardly forget bad experiences. So if you and your friends are having a barbecue on your patio, the last thing you need are ants crawling all over the food and BBQ smoker.

If you have a problem with ants in your patio, lawn, or garden shed, an ant killer can help get rid of the problem. A patio cleaner can also be useful, while a moss killer for lawns and a weed killer will ensure that your lawn is purely grass.

However, not every ant killer will be effective in eliminating ants in your compound. Here is a guide to help you make the right choice.

Now, before you set out to purchase an ant killing solution for your homes and gardens, you need to put certain things into consideration. This is because not every product out there will work as efficiently as you want them to. And then there's the manner of application. Simply put, you don't want to end up buying what does not suit your fancy or get the specific job done.

To avoid that, we've put together a detailed buying guide so you can follow the right direction and make the perfect purchase. In this guide is a list of features to consider; each expanded intricately for your understanding. So, before you go out to fortify your ant-killing arsenal, remember to look for the following features;

The Type

Ant killers come in different forms, each perfect for a particular kind of problem. Granules, baits and ant killer gel are ideal for eliminating nests and colonies, but different brands have different time frames for results. They're also very convenient, requiring you just to apply and get on with your business. But, if you wish to enforce a more hands-on solution, liquid insecticides and aerosol can sprayers is the answer.

These types give you a higher sense of control- not to mention the satisfaction you get from watching those critters crawl in agony.

The Quantity

The size of the area to be treated will determine how much of the art killing product you purchase. Liquid insecticides tend to come in litres, ranging from 1 to 5, depending on the manufacturer. Granules and powders are usually sold in smaller containers, though the brands promise tremendous results from little application.

Aerosol and are also small and are most suited for indoor use, specifically in bedrooms, kitchens and stores. If you're treating a lawn or ample patio space, get an ant trap or bait station. These guarantee more results with little resources and are most effective for tackling ants nest in the lawn.

The Target

Not all ants can be eliminated in the same way as some are hardier than others. While common black ants and meadow ants can be easily controlled with most of the products on the market, red ants are much more difficult to control. If your target is a colony of red ants, go for a product made explicitly for red ant solutions.

Do not make the mistake of buying one that promises additional extermination functions. You stand a better chance of winning against red ants if you're fighting them with a product that targets them alone.

User and Environmental Safety

It is essential also to consider the ant killer you're buying is safe for general use. Some products are potent and sometimes emit a robust and invasive smell.

If that would be a problem for you, then perhaps you shouldn't pick that. Also, many products are pet and children safe, though, in the case of liquids and sprays, it is advised to wait until they're completely dried.

If you have kids or pets at home, you might want to consider going for a product such as those or, in sporadic cases, products that pose no threat whatsoever to users, pets and kids.

You also have to consider the surrounding. Some products aren't specific but employ a 'Kill em all and let Nature sort em out' approach. If environmental impact is a big deal to you (which should be), then perhaps you need to make sure that's not the kind of product you're buying.

Ant baits and traps are environmental and user safe and pose no threat to kids and pets. Certain ant killer powders also promise this feature. However, most liquids and sprays do not.

The Versatility

You can decide to go for an exclusive and killer or a product that also takes out their neighbours. Depending on your original reason, you can choose to go for a product that targets ants alone. In such cases, bait stations and traps are your best bet. But if you wish to take out every critter that has ever crossed your kitchen floor, go for a product that kills not just ants but other insects as well.

Powders are very indiscriminate in this aspect, as a spray as well. Insecticides, as the name implies, are perfect for this option.

The Price

Do not believe the saying that expensive is better. Big lie. The price does not always indicate the quality of a product. Yes, some of the highly effective products are on the steep price end, but many moderately priced ant killers are also of top quality. Make sure you check the features of any product you find attractive before bothering about the price.

Also, consider customer suggestions as many have used these products and can tell you if it's a top performer or just a tough-smelling bottle of impotence.

What are the Different Features?

One main feature many users find handy in most ant killers is the speed of delivery. Most insecticides tend to provide results in the space of a few hours.

However, in the case of ant baits and granules, this might take days. So, while some users go for products that offer you quick relief, others prefer to take the long-lasting approach by taking the fight to their nests.

Another feature many users find handy is the ease of application. Generally, users prefer to go for products that require the least effort in use and application. Ant baits, granules and poison traps tend to get more considerable attention in this aspect.

Others still consider the environmental friendliness of the product. Users find it handy when a product does not require them to vacate the premises of application due to possible toxicity. Powders and ant baits are ideal in this situation and attract customers of such preferences.
