When it comes to ant problems, the first thing you need to do is identify the ants you are having a problem with. Large red ants are actually carpenter ants.
Carpenter ants can be red, black or a combination of red and black. You want to differentiate between these ants and termites.
Termites, like other ants, have a segmented body but it is very hard to see that. Termites will look like they have a solid body. They swarm at about the same time as carpenter ants so you want to make sure you know what you are dealing with.
It is a misconception that carpenter ants eat wood. They don’t eat it, they live inside it. You can also find them living in voids in your home, in cinderblocks, and in your attic, under the insulation.
Carpenter ants leave behind waste that is a sure sign of their presence. It is made up of little pieces of wood, bits of insects they have eaten and other waste. If you see this, it is a good sign that carpenter ants are nearby.
An established colony of carpenter ants can be made of up to 100,000 ants. These colonies will have sub-colonies of up to 15,000 ants. The ants will travel between colonies and that is when you will spot them.
You want to treat along the ant trails for best results. Do not use repellants from the hardware store. If you do, the ants will just find another path and build new sub-colonies. You want them to continue walking on the path in order to kill them.
Spray a pesticide anywhere you see ants. Spray under the eaves of your home and anywhere else that you actually spot the ants.
Another method to get rid of these pests is to use ant baits. The ants will take the bait back to the larva. The larva digests this and it becomes food for the worker ants and the queen. In this way, you are getting rid of the next generation of ants and the workers and queen.
There are many types of baits on the market. Some are safer and contain ingredients like boric acid. Others are more toxic. Read the labels and decide what works best for you.
