We have had introduced species such as L. rufescens, the Mediterranean Recluse, in a few locations in NYC and these are established populations. American roaches are a favorite food source. Tom also had collected this species from the Philadelphia area (he sent me specimens years ago). There have been very few introductions of the Brown Recluse into NYC . Loxosceles spiders can also go long periods of time without feeding. Spiders in general have slow metabolisms. Actually the number collected by glue traps might not make a dent in the actual population. Here's an example from around 2002 (J. Med. Entomol. 39(6): 948-951(2002)) where a colleague of mine investigated. A person had been bitten during the time when the collecting process was undertaken, but not while living in the home. The spiders were both collected from glue boards (+- 800) and searched out (+- 1200) and hand collected. You might want to read the article - there's a description of the home and construction details. Online reference to story: Over a 6 month period, "...2,055 brown recluse spiders collected in a Kansas home of a family of four. Despite the abundance of spiders, no one in the family received bites from the potentially dangerous arachnids." Lou

In order to give you some help with your situation, I'd have to know more about the construction of your building. Is there a basement? A crawlspace? What surrounds the building? Does anyone actually live full time in the building? You've certainly made a dent in the population with your trapping program.

A significant number of brown recluse spiders were caught, seventy in a two month period of time. Fishing for suggestions on other ways to control them besides sticky traps. I gather insecticides are largely ineffective. -- John Timothy Ataloa Lodge Museum<http://ataloa.bacone.edu/> ---------------------------------------------------------------------- To send an email to the list, send your msg to [email protected]<mailto:[email protected]> To unsubscribe from this list send an email to [email protected]<mailto:[email protected]> and in the subject put: "unsubscribe" - no quotes please.
