Borax is a boron compound and appears naturally where seasonal lakes evaporate repeatedly. The mineral is mined commercially in Searles Lake, California and in the Southwestern United States. This mineral may also be extracted synthetically from boron compounds. Keep wiping down those counters and stay vigilant against these resourceful little ants.

How Cinnamon Works to Deter Ants
However, the threat that carpenter ants pose to the structure of your home can be significant. Since they hollow wood out to build their nests, if they get into the wall voids of your house and stay there undetected, they can cause catastrophic levels of damage. Seeing carpenter ants indoors during winter means that there is an inside nest. Sometimes worker ants are carried in with firewood, but these workers are not able to start nests or cause any damage in homes. Parent carpenter ant colonies sometimes establish one or more satellite nests in nearby indoor or outdoor sites. The workers of satellite colonies move frequently between their nest and the parent colony.

They can also nest in homes and buildings, in enclosed areas where the wood is damp, wet, or decayed. If infestations grow, the carpenter ant colony may expand into sound wood. They usually have more than one nesting site, including a parent and satellite colonies. Boric acid is a more concentrated form of the same borax that is used to lace ant baits.
While black carpenter ants are common, you may also find a combination of black and red, red, or brown. Termites have a thicker body and antennae that are not elbowed. Workers also are white and smaller than carpenter ants, about 1/8 to 3/16 inch long.
Signs of a carpenter ant infestation
Even then, switch the type/brand of bait periodically since ants can develop tolerance to the bait with long-term exposure. Keep in mind that although mildly toxic, borax should still be handled with care and kept away from children and pets. The main thing to consider when comparing the various ant traps is the main active ingredient in each of them. Borax may be mildly toxic but it is still not a substance that you want to handle unnecessarily. Store-bought baits generally come in ready-to-use containers where you only need to open and place the bait without touching any toxic substance.
How Much Does an Exterminator Cost?
Winged males are typically the first to emerge when environmental conditions like temperature and extended daylight signify that it’s time to swarm. If conditions are right, the male releases a pheromone that stimulates the female to leave her nest. 'The satellite nests act to expand the foraging range of the parent nest, and they are in frequent contact with the parent nest to share resources. Once you locate the nest, using an insecticide like Raid can take out the pests, Russell says. We back up our pest control recommendations with a detailed rating methodology that we use to objectively score each provider.
Pyrethrins are toxic to fish and other aquatic life, and they have been known to cause serious allergic reactions in humans, especially asthma sufferers. Borax is a naturally occurring mineral that works by interfering with the ants' digestive processes. As worker ants continue to carry the material into the colony, the entire group gradually starves to death.

Replace Wet, Decaying Wood
While the control of other household ant colonies requires similar exclusion and sanitation tactics, the control of carpenter ants seems to be as much of an art as it is a science. Place the baits along ant trails that you have seen for the best effect. This is a great recipe for protein-feeding ants such as odorous house ants, Argentine ants, pharaoh ants, southern fire ant, thief ant, red imported fire ant, and pavement ants among others. Keep in mind that various ant species have different feeding habits and food preferences. A single species of ant also has different nutritional needs depending on the season and may change its food preference mid-way into you setting up the ant traps. It is for these reasons that you may have to experiment with various kinds of home-made borax ant baits until you find one that the ants will actually take.

Use wood preservatives on your windows, doors, pantry, attic, plumbing areas in the kitchen and bathroom, and other suspected areas. These ants excavate wooded areas of properties and make them hollow. Ants have a constricted body structure with only one segment between the thorax and abdomen. Ants have unequal wings, with the front pair being longer than the other.
More often, the general contractor subcontracts out the various building stages to different individuals, including carpenters. Fenoxycarb is used in baits specifically targeting fire ants and generally comes in granular form. It is not well absorbed through the skin and has low acute toxicity to humans. This ant bait is a good alternative for the sugar recipe described above. To make the ant bait, mix a small amount of jam with 2 tablespoons of borax and combine thoroughly.
Homeowners very often confuse carpenter ants with termites, since the structural damage they cause can be similar. But termites consume wood, while carpenter ants merely tunnel through it to create nests. The presence of fine wood dust around the entry point to the nest is a strong sign you are dealing with carpenter ants rather than termites. Control of carpenter ants in trees is important if ants are entering homes from colonies in trees. Contact a pest management professional if control is necessary. The best way to control carpenter ants is to locate and destroy the nest, replace damaged or decayed wood, and eliminate any moisture problems.
Carpenter ants can be difficult to get rid of entirely, since they tend to build a central nest and several satellites. The central nest is often outside somewhere, like in a wood pile or old tree stump, with the indoor nests usually being satellites. If this is the case, removing the ants entirely is going to be a challenge.
Often, your best bet is to eliminate the source of moisture that’s drawing carpenter ants to your home, as well as sealing any sources of food that might keep them coming back. Like other ants, they use scent trails to return to food and nests. If you can clean these thoroughly with ammonia, the carpenter ants may not be able to find their way. There are many different species of carpenter ants, so they can vary greatly in appearance with sizes ranging from 1/8 inch to 3/4 inch in the largest species.
