Many people have come to me expressing their frustration regarding ants in their residential settings. Well, for many individuals, these little insects are very irritating, and getting a strategy to eliminate them is priceless. Prior to becoming an entomologist, I also had my own share of struggles with ants, and never knew of any 100% effective way to get rid of them. I received suggestions, but none had satisfying results.

I tried several poison products, and though some ants died, the products were not effective in eliminating entire colonies. The ants kept reappearing after a short period following treatment. Now I have the expertise needed, and I’ve helped numerous clients eradicate ants and other insects from their homes and places of work. Today I understand better why contact poison never worked, and I recommend using baits to kill ants.

My review

What makes baits effective in getting rid of ants is that they not only have the poison but also have luring ingredients which make ants leave their hiding. Basic contact poison will work only when ants happen to come across the poisoned food, and they leave chances for some ants to survive. In that case, if you’re wondering, “do ant baits work?”, the answer is yes. Still, there are numerous ant baits around, and some are substandard products that do not promise satisfying results.

You might be wondering how you can understand which ant bait is pleasingly effective and safe to use either indoors or in an outdoor setting. Well, it is the reason why I decided to do ant bait reviews of the most effective products on the market and to provide infested homes owners with an informative buyer’s guide.

The attractant in the liquid draws ants from their nests and hideouts, such as cracks. Therefore it can wipe the entire ant population from your residence in a short while.

The liquid bait lasts for several weeks, and it eradicates ants for up to a 3 months span. Over this period, the liquid remains fresh and active, thanks to the stay-fresh tab, which is designed to ensure that the liquid does not dry.

Ant Baits Purchase Guide – What to Look For

Considering the extensive variation in ant baits by different manufactures, here are important aspects to consider when purchasing for purposes of effectiveness and great results:

  • Target ant type

It is justifiable to say that there is no single best ant bait for all infestation situations, but it is vital to choose one that best fits your circumstances. The first thing to consider is the type of ants you are targeting. There are numerous ant species, and different baits have been manufactured to eradicate different species. However, there are baits that work on a wide range of species, some over 30 ant types. You can check the manufacturer’s guide to see whether a bait is good for your target species.

  • Location of infestation

Whether the ants are outside or inside the house is an important factor to keep in mind. There are baits that have been specifically designed for outdoor use, others for indoor use, and some can be used in either setting. Most outdoor baits can withstand different weather elements, and therefore if you use an indoor ant bait in your yard, it might not produce satisfying results due to fluctuating weather elements. For example, liquid indoor baits are susceptible to drying when exposed to sun and therefore are not ideal for outdoor use.

  • Type of bait

Depending on the nature of the infestation, this should help you determine which bait type to go for. There is a number of bait types, which include liquid, granule, gel, and powder baits. Infestations can range from intensive when you are dealing with a large swarm to light with just a few ants with several nests around.

Granule and powder baits are typically efficient when dealing with a large swarm as the bait can be easily broadcasted over a large area. Noteworthy, these two types are most efficient when dealing with ants in an outdoor setting, as the application is easier. Gel and liquid baits are great when you have identified the exact locations of the nests, more so in an indoor setting. It is easier to apply these types of baits at the nest entrances, in cracks, and under furniture. Most gel baits come packed in a syringe-like container, and the narrow nozzle enables one to place the bait as close as possible to the colony.

  • Active ingredient

Different manufactures use different elements as active ingredients in their baits. Though not a major consideration, the active ingredient can be something you might want to reflect on when buying an ant bait.

How to Use an Ant Bait

Many people are not sure of how to use ant baits to obtain the best results. If you want to properly apply a product, it is first important to understand “how does ant bait work?” Ant baits are created to get rid of entire colonies, and that’s why most are slow-acting to allow exposed worker ants to contaminate other members of the colony.

The first thing to do is to observe the swarm’s movement. You can look for their favorite scavenging ground to understand where they enter your house and where their nest is. Getting this information will help you place the bait strategically for efficiency and effectiveness.

Considering there are different bait types as regards the packaging, different manufacturers give a step-by-step guide on the bait placement procedure. Check out the recommended procedure and follow it accordingly. Nonetheless, a general strategy that applies in all settings is to place the bait closest to the nest entrance. Doing this, you’ll press in the ants’ scavenging radius, and therefore ants are likely to find the bait faster.

FAQ

man uses ant bait outdoors

How long do ant baits take to work?

It takes approximately 48 hours for an ant to die after consuming the bait. Within this timeframe, the exposed ant goes back to the nest carrying the bait, and this way, it contaminates the entire colony, which eventually dies.

How do ants pass bait to each other?

Once a worker ant has ingested a bait, the effect is not instant, and therefore the ant goes back to the nest. Considering a worker ant’s job is to look for food, they take contaminated food back to the colony where other ants, including the queen, feed on the contaminated food.

What happens to ants when they eat ant bait?

Ant baits typically affect the digestive system of the ants. The sweet lure attracts the ants, which then consume the poisonous bait. When the bait is ingested, the active ingredient contained interferes with the internal systems, and this eventually leads to death.

Are ant baits safe for pets?

Ant baits are generally safe to use around pets. However, it is important to remember that different baits have different substances as the active ingredient, and some of them, such as boric acid, are toxic to pets. An animal would need to consume large amounts of the bait for it to be affected. Despite the little risk, it is important to exercise some precaution regarding where to place the bait.

Looking at some of the widely used active ingredients in baits, borax comes as a white powder and is mostly used with food-based attractants in ant baits. Thiamethoxam is another active ingredient in many ant baits, and one of the safest, having shown minimal effects on humans and pets and approved by relevant authorities. Indoxacarb is another widely used pesticide constituent, and it is considered by the EPA as a ‘reduced-risk’ active ingredient, so it is suitable for use in domestic settings.

The Bottom Line

Ants can be such a nuisance, more so in swarms. The use of baits is the most efficient strategy to eradicate them as it makes it possible to reach and kill the queen. Worker ants take the poison to the queen without the need of her coming out, therefore ending her colony and future generations. However, it is vital to purchase the right bait depending on the place and nature of the infestation.

Whether or not to go for an indoor bait or an outdoor bait depends on whether the swarm of ants is inside the house or in your compound outside. Also, consider your target ant species, as some baits have been specifically manufactured for killing specific species.
