I'm more familiar with Manhattan populations, but I know of 1 or 2 in Queens. Tom- you should send examples over from the various Loxosceles populations that you've come across so that we have positive records of the species from these locations. Lou

Either natural pyrethrum or synthetic pyrethroids are dynamite in this kind of situation. And in answer to Lou Sorkin's comments, yes, I have found Loxosceles rufescens in several locations in Philadelphia. I was sure they were L. rufescens, but I relied on Lou graciously positively IDing them. They are breeding populations. It seems they're located in the municipal underground steam lines to a variety of private and municipal buildings in center city Philadelphia and under the U. of Penn campus. I've trapped hundreds in several situations. These are not ones occasionally introduced; no, these are breeding populations.

What do they appear to be feeding on?; 2.) How are the spiders and prey getting inside? Most insecticides fail because the spiders do not actually come in contact with them. Fogging can be very effective, but fogging can be highly deleterious to objects and artifacts within the museum. The answer to the problem is to reduce or eliminate access for both spiders and prey by tightening the building up as much as possible. Forrest E.

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] To unsubscribe from this list send an email to [email protected] and in the subject put: "unsubscribe" - no quotes please.
