Diotomaceous Earth
A quick essay on DE. It is the "skeletons" of microscopic aquatic organisms (diatoms) that died over millions of years, with their mineral skeletons sinking to the bottom of the aquatic environment and building up huge deposits that now can be mined. There are both freshwater and salt water DE, and freshwater DE is much lower in respiratory hazard due to lower levels of crystalline silica that can be inhaled, and which do the damage to our lungs. MotherEarth Dust, for example, is freshwater DE. In addition, no one should ever use swimming pool filter DE, as this has been treated and offers a much higher respiratory hazard. DE for pool filters also is not labeled for pest control uses, and it is imperative that pest management professionals stick to what is labeled for our industry.
DE can kill all insects and other arthropods, so it is just as deadly to beneficial insects as it is to "pests". DE kills by cutting into the protective coatings on the exoskeleton, and absorbing moisture and allowing the insect's internal fluids to escape. Arthropods die by desiccation and dehydration. One of the uses of DE in pest management is to apply it directly to unprocessed foods that are in storage, such as grains in bins or silos. One study in Canada showed up to a 95% drop in the number of pest insects in stored barley.
One should remain cautious and careful as you apply DE dust, and keep it confined within the voids where the pest insects will be. Regardless of its low oral toxicity, as in everything, it is not non-toxic. Toxicity is always related to dose or exposure. DE works by dessication, that is, it cuts the soft appendages between the exoskelleton and dehydrates the pest. That same principal can work on the treaters pulmonary system, as well. without proper use or protection. DE may not be "toxic" but improper exposure can do serious damage if not used correctly. DE should be treated as any pesticide. Too strong of a comfort level with any pesticide can lead to excessive use. We can read the same kinds of statements about boric acid, on websites that are pushing this material as an alternative to "toxic" pesticides, but the educated person recognizes that boric acid can be a dangerous material if ingested. DE definitely is not harmless, as there could be that respiratory hazard or skin irritation, but it is a wonderful choice for pest management with a nice profile of low toxicity and hazard.
Since it is a mineral it does not degrade the way synthetic molecules do, and in a dry void should be active and effective for many years.
The most important determining factor for kitchen cabinet quality will be the material. Kitchen cabinets are most commonly built using plywood (A), MDF (B), or particle board (C). A plywood cabinet will almost always be of the highest quality when compared to MDF (medium density fiberboard) or particle board. It is very rare to find solid wood cabinets, and if you do find them they are not as good as they sound, they warp easily and crack easily. MDF or particle board cabinets can also warp easily but they absorb moisture very easily which results in swelling and odor absorption. Another important determining factor in selecting a good cabinet will be the finish. Any wood cabinet will usually have a veneer covering that is used to make the cabinet appear to be made of solid wood. 
This species is restricted to the West, ranging from British Columbia to Mexico.
These insects live in wood which has a relatively low moisture content (12% or less), in the Western United States, Northwestern Mexico, and Florida. They are swarmers 7/16" to 1/2 " long including wings. Their heads and pronotums are orange brown, abdomens are dark brown, and wing membranes and hardened veins are blackened. They have Antenna with 10-11 segments. They are not hairy, their tibia exhibit no spines along their length and they have no pad between their claws.
As their name implies, dampwood termites locate their colonies in damp, sometimes decaying wood.
Anobiids Beetles are the most commonly encountered of the powderpost beetles. They are also called Deathwatch beetles because of a tapping sound they make when mating. Heard in the quiet of the night by people sitting with an ill person, this tapping was believed to indicate that death was near.
Wood Decay fungus (poria incrassata)
Several species of carpenter ants, Camponotus spp., are capable of damaging wood in buildings and other structures. Carpenter ants cause problems mainly in mountainous areas and in forested rural areas along the central and northern coastlines of California; they may also invade buildings in urban locations.
Queens typically are the largest ants in the colony. After selecting a nest site, a queen will begin laying eggs and caring for her brood. The first workers that develop assume brood care, leaving the queen to simply lay eggs. Ant colonies can have single or multiple queens. The number of queens in multiple queen colonies varies by species, ranging from a few queens to nearly half the population in a colony. Depending on the species, queens may live from months to years.
Males serve one purpose: to mate with the queen. Males typically die soon after mating, and are normally alive solely during the colony's reproductive stage.
