As for the spiders & etc I use the 4" X 7" glue boards with the wax paper peel off top protector for insect control.
Placing about 20 of them around a 2k sq ft basement it is revealing of the assortment of undesirable visitors you have. Every so many months I replace the glue boards. Really makes for a greatly reduced bug environment. Lining them along the floor/wall crevice seems to yield the most productive catch.
I notice once a bug gets snagged on one board that poor stuck critter draws a crowd. Not sure if it is for dinner, reproduction or just to laugh at'em. In any event some traps only get a few, but the rest of the traps have a crowd.
Haven't found anything good enough to cut down on certain relatives. tt
what a great idea! I dont have an infestation by far, but just enough to give this idea a try. Thanks Tom
