I have a client who puts a coffee can in the ground with a board over it . Scorpions fall in at night . It's a trap . They have caught 13 in 3 weeks using 2 of these traps , no bait , just lots of scorpions . They are just walking along and fall in . There must be millions of them around here My question is I have 3 containers , one 'pion in each plastic container . 1 with Delta Dust 2 with ECO Exmpt D 3 with Boric Acid Guess which ones dies first . I am gonna try Diatomaious earth , too . As soon as I get some . BTW , I still have about 6 scorpions living in fish bowls in my office .
