Carpenter Ants - How to Prevent an Infestation

Carpenter Ants (Camponotus) are the largest ants found throughout the United States. They range in color, from black to brown, or a combination of both. Black carpenter ants are commonly found in the Northeastern side of the U.S. They have 6 legs, elbowed antennas, a slender waist and the size range from 1/4 of an inch, to 1/2 an inch for a worker ant, and 3/4 inch for a queen. Black Carpenter ant swarmers emerge from a mature colony usually beginning in early spring (May) through the summer. The carpenter ant swarmer's has 2 pair of wings, but the second pair are shorter than the first.
 Carpenter Ants can cause serious damage to wood inside and outside your home. Unlike termites that eat wood, carpenter ants excavate galleries and build nests to rear their young. This is especially harmful in wood support members such as sill plates, floor joists, rim joist, posts and beams, to mention a few. They can be found in logs, firewood, moist damp wood, and tree stumps. Though they can be found in dry wood, carpenter ants prefer wood with a high moisture content. The longer the colony stays in the wooden structure, the more damage they will do to your home. Over time any structural wood they attack can be weakened, resulting in unlevel, or sagging floors, bulging walls, or worse.
 Debris that carpenter ants produce from excavating wood, such as saw dust like shavings mixed with body parts of dead ants, is a clear indication of a nearby nest.

Prevention

Carpenter Ants are usually found near moisture, and rotting or decaying wood. Home owners should make sure their gutters and downspouts are functioning properly. If holes or leaks exist in the gutter system, that can allow rain water to accumulate around the home, thus attracting carpenter ants. Replace all dysfunctional gutters and downspouts. Adding downspout extensions, or splash blocks is also helpful in keeping water from accumulating around the structure.
The grading around the structure should slope slightly to allow rain water to drain away, instead of toward the structure, or from settling around it.

Where wood is in contact with soil, these areas should be closely examined. If nests are discovered, replace the infested wood if seriously damaged. Exterior steps, posts, or railings should rest on concrete pads instead of in, or on the soil.

Stopping water from entering the home is very important. Repair all roof leaks and replace missing shingles if needed. Have the flashing on the roof inspected, especially roof penetrations such as plumbing vents and chimney flashings. Clean gutters of leaves and dirt to prevent them from overflowing.
Caulk and screen any potential entryway ants may use to gain access, like doors and windows, and outside water connections. Ventilate areas where moisture accumulates, or where high humidity exists, such as crawlspaces, attics and storage rooms.

Vegetation in the form of bushes, hedges and tree branches should be trimmed back at least one foot away from the exterior walls, and tree branches overhanging roofs should be cut back. When vegetation is in contact with exterior walls, or roofs, this is conducive for pest infestation.

While wood mulch is good for plants, it also attracts wood destroying insects, including termites. If you have wood mulch, or plan to have some put around your home, many pest control professionals strongly recommend having the mulch treated to prevent the infestation of wood destroying insects. Wood mulch can be sprayed, or granular bait can be applied.

 Carpenter ants have their place in nature, however, we don't want them in and around our homes. With careful planning, and good home maintenance and repair, we can reduce the use of pesticide and co-exist with the insect world.

Carpenter Bees And The Damage They Cause

Termites and carpenter ants are the most destructive insects of wood in structures found in the United States. Yet another insect that must be addressed are Carpenter Bees. Although not as destructive as termites, or carpenter ants, carpenter bees can do their fair share of damage to the exterior of structures. During the summer months, Home Inspectors and Pest Control Professionals (PCP) will be attentive to the damage that results from an infestation of carpenter bees.

                                                                    Characteristics of Carpenter Bees

                                                                                   

Carpenter bees Closely resemble bumble bees in that they both have a stocky or robust build. The major difference in their physical characteristic is that the top surface of the abdomen of the carpenter bee is bare black and shiny, whereas the bumble bee has many body hairs and appears fuzzy. Carpenter bees have a dense area of hairs on the hind legs, bumble bees however have dense yellow hairs on the abdomen and large pollen baskets on the hind legs.

                                                                           Structural Damage

                                                                               

Carpenter bees do not eat wood, but the females bore circular holes, about 1/2 inch wide at a right angle for about an inch deep into the wood they infest. They begin to excavate galleries in the direction of the wood grain for about 4-6 inches and this is where they make their nest. They can nest in all species of dried seasoned wood, but they prefer softwood like cedar, redwood, cypress, pine, and fir. They will bore in wooden members on houses such as eves constructed with pine and on decks, fences and dead tree limbs.  It's these areas that home inspectors and pest control professionals will take a closer look to determine if any activity exist. Carpenter bees are known to return to the same wood year after year to drill nests and lay eggs. If left untreated the wooden members can weaken resulting in costly repairs.

                                                                                   Treatment

How can you determine if carpenter bees are nesting in structural wood on your property? If you see a number of bees hovering around the eves for an example, they're protecting the entrance to a gallery and will chase away any intruders, including humans. The males do not sting, however who wants to wait around to determine males from females? If you suspect you have carpenter bees, call a pest control operator. Many have found closing the holes with corks helpful. Painting the wood will not protect it from carpenter bees, but it is helpful since they prefer bare, exposed wood. Some pest control professionals as a last resort use a pesticide in the form of dust that's applied inside the galleries that acts as a residual and is effective in the control of carpenter bees.

Preventing Wooden Decks & Porches from Termite Infestation

  Wooden decks and porches if not properly cared for can be an all day breakfast, lunch and dinner buffet. Termites, the most destructive insect of wooden structures are opportunist with an unending appetite . They are masters of taking advantage of a neglected home. So how can home owners keep their outside recreational areas free from termite infestation? Well, there are three key ways.

First, it's important to give a visual inspection of all accessible components of your deck and/or porch. The illustration above gives the names and shows the areas of the components you should inspect. The posts, beams, joist and face-boards are the areas you want to especially examine because they are closest to the ground where subterranean termites emerge from. In these areas look for mud-tubes that termites construct to travel back and forth from their nest in the ground to the wooden members. Have with you an instrument with a pointed edge, like a knife, screwdriver, or ice pick. Gently but firmly probe areas of the wood. If the instrument goes through, likely there's termite damage. If you see a lot of cream colored insects, about 1/8 to 3/8's of an inch in length you have termites.

Check for loose rails, steps and balusters as well as columns. Probe them too because the outside of the wood may look fine, but could be hollow inside. If the wood is sound, then tighten them with nails, screws or bolts. Check the decking for damage such as splinting and loose deck boards. Walk across the deck to determine if any areas are weak or sinking. If possible check underneath the deck or porch, especially the undersides of all joist, beams and decking.

Second, make sure that you have good drainage. If you don't have a deck or porch cover make sure the deck boards are spaced so that rain water will not accumulate on the deck. The grounds around the house should be sloped so that water drains away from the house, not towards it. Post should be mounted on piers, not in the dirt or ground. Wooden steps should rest not on dirt, but upon a concrete base or apron that extends at least 6 inches above grade. Paint or stain all wooden members, including the undersides and cut edges.

Finally remove any wood debris from under and around the house and deck. Scrape wood, tree stumps, mulch, boxes and branches all attract termites to your home.
A visual inspection is the beginning of protecting your home from termite infestation.

 If you think you have a termite infestation on your porch or deck, call a pest control professional for an inspection and treatment options.

Pest Entry Points

Pests can invade homes in a number of different ways. Some gain access from luggage when returning home from trips. Some get in from package deliveries  Another way is from the purchase of used furniture. If you ride public transportation, you could bring an unwanted visitor in with you. Even movie theaters have been known to harbor insects that would love to come home with you, such as bedbugs and roaches. Sometimes even our guest that comes by for a visit may leave behind a few unwanted visitors.

The most common way pests gain access is from unsealed openings in and around our homes. Ants, spiders, earwigs, and termites are just a few of the insects that take advantage of unsealed openings and invite themselves in. Even rodents such as mice and squirrels enter attics, basements and crawlspaces through unsealed openings. An example is the house mouse that can squeeze through any opening that is larger than 1/4 of an inch. A rat needs 1/2 an inch or more. Rats and mice can climb any vertical surface where they can get a claw hold, this would include any  vegetation growing on exterior wall surfaces, and rough exterior wall surfaces like masonry, brick and stucco. They have even been seen descending head first down a rough wall.


                                                         How To Prevent Entry

Seal cracks in exterior foundation walls

The best way to prevent rodents and insects from getting in to your living space is by periodically inspecting the exterior of your home. Look for worn caulk around windows and door frames. This includes garage vehicle doors with weather strips. If you find the caulk is worn, remove the rest of the caulk completely and reseal with new caulk. Another area to inspect is the exterior walls. Cracks in foundation walls like the one in the picture above should be sealed to keep out not only insects such as termites, but also moisture which can lead to mold growth.

Unsealed plumbing penetrations is another area for observation. Outside water faucets and/or plumbing lines for a central air condition unit check that all wall penetrations are properly sealed. The picture below shows enough space for rodents and insects to enter with ease.

Seal exterior wall penetrations

Finally all interior walls should be repaired. If insects and rodents have access to the inside of walls, floors, and ceilings, they can roam through out your house, reproduce and spread germs and diseases. Your pest control professional will check these areas and more to help aid and prevent pest entry.
