Powder post beetle larvae cause millions of dollars worth of damage in the US and Canada annually, and are almost as destructive as termites. Adult beetles lay their eggs in the surface pores of wood. The larvae bore into the wood as soon as they hatch. Living in the wood, they create tunnels called galleries as they eat their way through the timbers. When the larvae are nearly full grown, they bore near to the surface of the wood and pupate. The adults bore out through the surface soon after pupation, pushing a fine powdery wood dust, usually a copper to yellow-gold in color, out of the wood as they emerge.
Baiting involves placing bait tubes or traps in the ground at intervals around a building -several dozen for a typical house. Pieces of untreated timber or other cellulose-based material are inserted into these tubes as bait for termites. The tubes are monitored and, when termites are observed feeding on the bait, it is replaced with treated bait containing a chemical that the termites then carry back to the colony. The chemical is slow acting, so termites are unable to associate its source with its effects. Over a period of several months, the entire colony may be destroyed.
Termites have a very thin cuticle (skin) and are subject to rapid desiccation (drying out) if exposed to the environment outside their enclosed habitat. In order to maintain a highly controlled environment, termites must live in a closed system. Colonies in wood are always contained within an outside shell of cellulose material. In this way, they are protected from exposure to the outside.
There are several natural methods available for combating termite infestation. However, these methods are not a silver bullet. "An ounce of prevention is worth a pound of cure", a popular phrase applies to this situation. If there is no issue of termite problem at first place than there is no need to worry. One of the best ways of preventing your home from termites is to move the things first.
The series of galleries (area hollowed out) created by termites in wood give a honeycomb appearance. These galleries follow the wood grain. Interior galleries contain greyish specks of excrement and earth, called frass.
Careful site preparation and clean-up can do much to discourage the colonisation of a new or existing building site by termites. Where forest or orchard land has been cleared, tree roots must be completely excavated and removed along with any other buried wood.
Powder post beetles only do significant damage when multiple generations continually re-infest the same piece of wood. Also, powder post beetle damage is restricted to hardwoods, and since most structural framing is made of softwood lumber it is rarely attacked by these insects.
Smaller versions of termite barriers, a termite services company will set bait stations in the ground immediately around your home. These small boxes filled with poison can help rid your home of termites as it attracts and poisons them. You termite services company will replace them with new bait stations when they begin to lose their effectiveness. Bait stations have become an increasingly popular way to control termites. The key is placing the bait stations in the most effective locations, so it`s best to contact an expert for placement and installation.
The environmental and health risks associated with chemical usage have led to the withdrawal of several termiticide products from the market. Barriers consisting of a layer of precisely sized sand or crushed stone below and around foundations are an alternative means of preventing termite entry.
The worker termites are white in colour and approximately 6mm (1/4 inch) in length. Their antennae are straight (not elbowed) and the body is not narrowed at the waist, which distinguish them from ants. They have chewing mouth parts and are responsible for foraging and feeding the dependent members of the colony. The hind gut of the worker contains protozoa (single-celled animals) which assist in breaking down cellulose into its component parts which are digestible by the termite. The worker termite causes the structural damages.
