Boric Acid Ant Bait
The previous post discussed the benefits of using ant bait stations as a method of ant pest control. This post goes on to consider the various types of baits which may be used. Whilst there are many different types of commercially available ant baits available over the counter (and online) – it is perfectly possible, and in many ways better, to simply make your own. Why not make getting rid of ants that little bit more ‘hands on’ by creating your own homemade ant bait. The reason we say that it can be ‘better’ to make your own bait is simply because it allows you to have complete control over the strength of the bait, and to modify it according to circumstances. All will be explained!
Why Homemade Ant Bait?
Whilst commercially available ant baits generally contain a slow acting poison (often around 5%) combined with an inert sugary based product (around 95%) – the proportions of poison in these mixtures are set at a fixed percentage. The advantage of making your own homemade bait is that you can constantly adjust the proportions of the various ingredients in the mixture yourself, once you observe how the ants are reacting.
Bear in mind that the ants which you are able to see only represent a fraction of the total number of ants in the colony. To eliminate the entire colony it is necessary to find some way of ‘using’ these visible (usually worker) ants to somehow unwittingly cause the destruction of their fellow ants and, ultimately, their queen. This is where the ant bait station comes in to play. The idea behind an ant bait station (also sometimes called an ‘ant control center’) is to provide a place which the worker ants will identify as a source of food. We want these ants to consider it as a food haven! What will then happen is that the worker ants will take some of the food back to the colony to share with the other ants – and ultimately the Queen. If the food that they are taking back is ‘laced’ with a slow acting poison, this should ultimately kill the queen. Remember that to completely eradicate a colony the Queen must die!
As the majority of ants are sugar loving, the principle source of food used in any ant station should be based upon a sugar source. You can make a simple sugar source by simply mixing around 7 oz of water with any sugar product such as honey, sugar cubes, molasses, etc. For the first couple of weeks do not add any poison to this sugar source. Let the ants get used to using the ant station as a source of free food. One tip here – try to keep the bait out of direct sunlight to prevent the sugar water from fermenting. Ants learn very fast and remember what they have learned so hopefully, within a short period of time (a few weeks), the ants will be using your bait station on a regular basis as their primary source of food. By placing your bait station(s) initially close to areas where you have had a problem with ants, what you will find is that these ‘problem’ ants are now using your station instead of wondering over your home or garden (wherever your problem areas were). Now start to move the ant stations gradually away from these problem areas and you should find that the ants will move with them. This is effectively a method of ant ‘displacement’. The size of the ant colony will be unaffected but the effect is to remove the problem to a different area – usually further away from your house. For some people, this may in fact solve the problem itself – you may be happy simply to displace the ants to a different location without actually having to kill them. Remember that the primary purpose of the ant bait station should be to control the ants. It does not necessarily have to be to kill them – although it has to be said that commercially available stations invariable include some form of poison in the bait. If, however, you find you are able to use your homemade ant bait to control the ants without needing to resort to the use of poison then so much the better.
Time to add the Poison!
Assuming that the ants have been using the ant station for a while and seem to be quite content to regard it as their primary food source then, if you consider it necessary, you may proceed to eliminate the entire colony by the subtle addition of poison to your homemade bait. The easiest and most effective form of poison to use for this purpose is boric acid. Boric acid was first registered as an insecticide in the United States in 1948 and basically acts as a stomach poison affecting the insects’ metabolism, whilst in dry powder form it is also abrasive to the insects’ exoskeleton. Please be careful when handling boric acid in concentrated form. Whilst is is generally considered to be not much more toxic than table salt – it can be dangerous if taken internally or inhaled in large quantities. Please wear gloves when handling it and keep away from children and pets. Boric acid is generally available over the counter at a local pharmacy (drug store), hardware, or garden store.
How much Boric Acid?
The trick here is to add just enough boric acid to your sugar bait so that the ants ingest enough to act as a slow acting poison. We want the worker ants to take it back to their colony and share it with their fellow ants and, especially, the queen. If you add to much boric acid, you will find that the worker ants will die before they can make it back to the colony and deliver their poisonous food. (This is not only ineffective but actually counterproductive since the ants which will be using the ant station are merely sterile female worker ants. If you merely kill them, the queen may simply produce more to replace them.) If you add too little boric acid, the problem is the reverse – the ants will simply not die. It is recommended that you start out by adding one teaspoon of boric acid and then observing the results. If you find that after a month or so, the ants are not dying, then increase to two teaspoons per cup. Alternatively, if the ants appear to be dying whilst at the bait station then the mixture is too strong.
We hope that you have found this information useful and informative and wish you every success in your efforts at getting rid of ants forever!
