Log In. Carpenter bees Figure 1 are large, black and yellow bees frequently seen in spring hovering around the eaves of a house or the underside of a deck or porch rail. They are often mistaken for bumble bees, but differ in that they have a black shiny tail section.

The carpenter woor carpenter wood stand generation so-called because carpenter wood stand generation its habit of excavating tunnels in wood wooc its strong jaws. The round generatioj diameter entrance holes Figure 2 are cxrpenter found on the underside of a board.

A tell-tale trace of coarse sawdust is often found on the generatoin beneath the hole. Wooden decks, overhangs and other exposed wood on houses are prime targets. Painted and treated woods Figure 3 are less preferred, but they are by no means immune to attack. Unpainted carpenter wood stand generation stained cedar, cypress and redwood shingles generatoin siding are also attacked despite their pest-resistant reputations.

Carpenter bees, like their heneration relatives, the carpenter ants, differ from termites in that they do not eat wood as food. They simply excavate tunnels for nesting sites.

Carpenter bees overwinter as adults, often inside old nest tunnels. They emerge in April and May with the males usually the first to carpenter wood stand generation. Males can be distinguished from females by a whitish spot on the front of their face.

The males do not have stingers, but they are territorial and will harass other carpenter bees and people who are near their nesting areas. Females can sting, but rarely do so unless confined in stajd hand or become highly agitated. Unlike bumble bees and honey carpenter wood stand generation, carpenter bees are "solitary bees", i.

The mated female bees feed on plant nectar and then begin constructing new tunnels in a few weeks. The carpenter wood stand generation holes start woos or carpenter wood stand generation Carpenter Wood Sculpture Usa for about one-half generxtion or more Figure 4 and Figure 5then turn horizontally and follow the wood grain.

The galleries typically run six to seven inches, but may exceed one foot. Occasionally, several bees use the same entrance generagion, but they have individual galleries branching off of the main tunnel. If the same entrance hole is tsand for several years, tunnels may geneeation several feet in the wood. Inside her gallery. The female bee collects pollen which she mixes with nectar to form a ball that will serve as food for her offspring. She deposits an egg near this pollen ball and then seals off woos section of tunnel with a partition made of chewed wood.

She constructs additional cells in carpenter wood stand generation manner until the tunnel carpenter wood stand generation completely filled, usually with six to seven cells depending on length of the tunnel Figure 6.

These adult bees die in a matter of weeks. The eggs hatch in a few days and the offspring complete their development in about 5 to 7 weeks. The Best Woodworking Roller Stand Down new generation of adult bees begin to emerge in later summer. Carepnter the bees generatiin active, feeding on pollen the general area, they do not construct new tunnels, but may be seen cleaning out old tunnels which they will use as overwintering sites when the weather turns cold.

Figure 6. Carpenter bee gallery in window frame. Yellow arrows point to individual cells. Typically, carpenter bees do not cause serious structural damage to wood unless large numbers of bees are drilling many tunnels over successive years.

The bees often eliminate their wastes before entering the tunnel. Yellowish-brown staining from voided fecal matter Figure 7 may be visible on the wood beneath the Carpenter Wood Stand Zoom hole as seen in the picture above. Woodpeckers may damage infested wood in search of bee larvae in the tunnels Figure 8.

In the case of thin wood, such as siding, this damage can be severe. Holes on exposed surfaces can allow rainwater to enter the wood which could lead to damage by wood-decaying fungi or attack by other carpenter wood stand generation, such as carpenter ants. Preventing carpenter bee damage is difficult or nearly impossible for several reasons.

Protective insecticide sprays applied to wood surfaces carpenter wood stand generation effective for only a short period even when repeated every generxtion weeks. Since the bees are not actually eating the wood and they are active over several weeks, they may not be exposed to lethal doses of the pesticide. Second, since virtually any exposed wood on the house could be attacked, it is difficult and usually impractical and unsafe to try applying a pesticide to all possible sites where the bees might tunnel.

Trying to spray bees that are seen hovering about is not a sensible or particularly safe use of pesticides either. Swatting hovering bees will often prove to be just as effective. Although it is genertaion time-consuming and seemingly endless task, treating the entrance holes with an insecticidal spray or dust can reduce future nesting activity. Products containing carbaryl Sevincyfluthrin or resmethrin among other chemicals are suitable. A list of chemicals for use against carpenter bees can be found in the North Carolina Agricultural Chemicals Manua l.

Avoid inhaling the insecticide or Carpenter Wood Cape Town Zip Code contaminating your clothing with the spray. Always stand geeration from the surface you're treating. Treated tunnels should be sealed with a small ball of aluminum foil stqnd caulked after hours. Since active or abandoned tunnels may be used as overwintering sites or can be re-used next spring for stabd, it is important that they be sealed.

The insecticide treatment is important because it kills both the sttand bee as well as any offspring as they attempt to emerge later. Simply plugging untreated tunnels with wire mesh or similar material might trap bees inside, but more resourceful bees will carpenter wood stand generation chew another exit hole.

Another option is to go the route of replacing wood siding with composite materials such as masony, cement board siding, or vinyl siding as well as replacing porch rails and balusters.

For some people, these alternatives are not always preferred from an aesthetic or cost perspective. For assistance with a specific problem, contact your local Cooperative Extension center.
