Max Force on Ants

If you get ants invading your house in the spring, you might try an ant bait.  The reason baits are good is that they take the product back to the nest thinking  it is food.  Then they eat it and feed it to everyone else, including the queen.  When she goes, the rest are not going to live long.  Most baits are either growth regulators or slow acting poisons.  They are impregnated into delicious tiny nuggets about the size of large sand grains.  These grains are scavenged by the workers looking for food to bring back to the colony.  The food is shared and in approximately a week, the colony dies out. 

This approach is pretty good since the colony is sometimes a little hard to find or destroy.  This way wandering worker ants can deliver the goods to the colony even if it is inaccessable to humans.  It is a pretty safe way to go since you use a little bottle cap full of bait crumbs and they are not all over your home.  A little goes a long way, too.  A bottle cap full is way too much; you just need a pinch or two.  If a cat or dog eats it, there is too little to hurt them.

The active ingredient in MaxForce is hydramethylnon, which you can read about on Wikipedia.  It is a slow acting stomach poison for ants.  It is low toxicity to mammals, although apparently fish are quite sensitive to it.  The Lethal dose to kill 50% of a population of dogs  is 2500 mg/kg or quite low toxicity.  Max Force is attractive to most all species of ants.

The other products out there to kill any colonies by bait method are growth regulators.  Insect growth regulators (IGR) disrupt the maturation of the insects into adults by not allowing the chitin of their exoskeletons to shed properly.  They never reach the reproducing stage and so die out.  Advance carpenter ant bait ( is available for carpenter ant infestations.  The smell of the bait is attractive to that species  and is especially good on them although other ants will take it too.

    Does Max Force for ants help much if the ants have become cellar dwellers in the walls of your home? If so, can you give the carpenter ants home restoration lessons before they consume too much of wood holding up your walls?

    PS: Are carpenter ants related to carpenter bees?

    It’s a little early in the day for you to have had that much to drink.
