Your home is different construction and vintage? Your neighbor’s home supports a large Loxosceles population but yours does not. Yes, I know you didn’t mention the tippy toe aspect but that’s normally what people think about spider tarsi and certain insect tarsi as well. The inference is there and it is usually one reason the manufacturers give for their products not working. But as we know, the product has to be placed in the right place to be effective. Lou

In truth, most PMPs don't put pesticides where they are needed most - behind, beneath, within. And, yes, direct hit works best and dusts are better than liquid sprays. I am very familiar with Rick Vetter's work and he and I are in frequent contact. The home referred to is just a few miles from mine and I am acquainted with the Bargers - Diane Barger is the junior author on the paper you cited. They are my source of brown recluse spiders when I do testing work for Bayer (my former employer) and BASF. Forrest E.

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 Louis N. Sorkin, B.C.E.

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]<javascript:window.top.openSendEmail('[email protected]','','','');> To unsubscribe from this list send an email to [email protected]<javascript:window.top.openSendEmail('[email protected]','','','');> and in the subject put: "unsubscribe" - no quotes please.
