You must check to make sure that it is allowed for use in public buildings.

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.

It housed a gradual build up of debris from eight years of service, which when inspected did contain larvae. We are now looking at having the elevator shaft floor thoroughly cleaned and sprayed. Our facilities provider has suggested using Gentrol, but we have only found it referenced with regards to beetles in the literature. Any comments on the efficacy of Gentrol for webbing clothes moths would be appreciated. We are also considering using an insecticide/desiccant combination - such as PyGanic, or Alpine Dust (two suggested by our facility providers).
