In the past few years I have found that in certain parts of Texas the brown recluse spider is increasing in number. As as professional I like to use a small glue board that can be folded up into a nice small box shape and be placed throughout the house. They are chemical free and work 24/7 in catching them. I like to put them on the floor and behind furniture, curtains and anywhere where they may hide. These glue boards last from 3-6 months . For a free sample , just call Michael at 214-793-9342.
