The only recourse with an infested piano is fumigation with Vikane. Vikane can only be used if someone has a chamber or it can be tented in a safe, indoor place if the temperature does not fall below 70 degrees F. during the entire fumigation (usually 24 hours).

A client has a piano which has been in the family for quite some time, having been shipped in from Colombia. As you know, drywood termites will often infest individual elements of furniture, leaving adjacent materials untouched. I've wondered about tenting the piano and hanging a Nuvan strip inside. Any thoughts? I would not have considered this approach with any of the old dichlorvos strips. An alternate might be painting the unfinished surfaces of the obviously-infested elements of its construction with a borate solution. Again, thoughts? See you in Reno? Forrest E.

As far as the use of the IGR’s in the elevator shaft, I agree with Tom that they will have limited effect on the juvenile population. A secondary benefit of using the product, however, would be the sterilization of at least some of the existing adult population. If you suspect there are a significant number of adult moths left in the building, the use of IGR’s might be justified. I also highly recommend Alpine. I used it in treating yellow jacket nests this year (which are historically problematic) and found it to be highly effective.

This is called the *piston effect. *The effect is essentially proportional to the speed of the movement and inversely proportional to the number of cars in the shaft (bigger shafts are less tight and there is a lot of air leakage at the doors). For example, with a single elevator car traveling at a velocity of 400 ft. per minute (fpm), there is a pressure differential of 0.08 inches of H2O. For a double-car shaft, it is only 0.02 inches of H20. The *piston effect* only occurs during car movement. The *stack *or *chimney effect*, however, can produce larger pressure differentials that generate air movement to balance pressures. The natural buoyancy of warm air will cause it to rise, creating a negative pressure in the lower areas and a greater pressure higher up. This is enhanced in heated buildings in the winter and partially reduced in air-conditioned buildings in the summer (the *reverse stack effect*). The *stack effect* is driven by building geometry and the laws of physics and *it never turns off. * The strength of the *stack effect* is influenced by numerous factor related to building height (the height of the stack), interior and exterior temperatures, location and types of openings and building envelope tightness (air leakage), exterior wind velocity and direction, whether and how the top of the elevator shaft is ventilated to the exterior (total area, automatically dampered), etc. For example, the stack-effect pressure differentials published by ASHRAE range from 0.07 inches of H2O at 30 ft. to 0.7 inches of H2O at 300 ft. Additionally, a 15 mph wind perpendicular to a building can result in a wind-effect pressure differential from the windward to leeward side of 0.12 inches of H2O. The *stack effect* can have significant unintended consequences and can lead to the movement of considerable volumes of air, moisture, smells, mold spores, dust, etc. up the shaft and through other parts of the building leading to the shaft. Interior conditions can be degraded with unexpected drafts and surprising temperature and humidity conditions. Importantly, condensation, with associated damage and biological growth, can occur in unexpected locations due to such air movement. Considerable amounts of expensive heated air (energy) are lost up the stack this way as well, as anyone who leaves their fireplace chimney flue open knows. The International Building Code and local building and fire codes have guidance on elevator shaft ventilation requirements. Some controversy remains about the best ways to handle fire and smoke in elevator shafts. Such air movement pathways may also provide access for vermin. The solutions include a deeper understanding of building science than is prevalent, great attention to detail during the design phase, and continuous supervision during the construction phase of a building. Some ventilation is obviously essential. However it needs to be properly understood and controlled. The importance of removing organic debris and potential bio growth habitat during construction, during renovations, during routine maintenance (which almost always needs to be better defined and more extensive), and during operations cannot be overstressed. Contractors must be told that such debris cannot be left behind, particularly in crawl spaces, under slabs, in attics, etc. and especially in the various interstices of a building where it cannot be seen and or easily removed. In addition to encouraging damaging biological growth, such debris can be a real fire hazard. William C. S.

It seems that cockroaches and bedbugs exposed to Hydroprene while undergoing instar stages of incomplete metamorphosis are rendered sterile as adults. According to the label, Hydroprene actually kills insects undergoing complete metamorphosis at the pupae stage. Obviously, not all of the pupae will be killed by the application, which will result in some or most of the upcoming generation being sterilized.

It had always been my assumption that Hydroprene was developed for insects that went through incomplete metamorphosis (like bed bugs and cockroaches), and that Methoprene was designed for insects that went though complete metamorphosis (like fleas). Since Dermestids, Clothes moths, and most other heritage-eaters go through complete metamorphosis, I assumed that Precor would be the choice to use if working with an IGR in a museum setting. Interestingly enough, there is a 3rd option out called Nylar that claims to work for both types of insect growth patterns. As far as the use of the IGR’s in the elevator shaft, I agree with Tom that they will have limited effect on the juvenile population. A secondary benefit of using the product, however, would be the sterilization of at least some of the existing adult population. If you suspect there are a significant number of adult moths left in the building, the use of IGR’s might be justified. I also highly recommend Alpine. I used it in treating yellow jacket nests this year (which are historically problematic) and found it to be highly effective. It has a great one-two punch, and is non-repellant, which will help contain the infestation rather than scattering it.

Gentrol holds larvae in the larval state; it usually does not prevent eggs from hatching. The Alpine Dust would be a good choice as long as the elevator pit remains dry. Thomas A.
