Insect sticky traps catch crawling and flying insects without sprays. For crawling pests such as cockroaches and pantry insects there are glue boards and glue books from Catchmaster, Catch Expert and MYDOO, including the Catchmaster Insect Trap & Monitor. For flies there are fly spirals from Edialux and Green Protect, the Bytrap Sticky Fly Band and large Catchmaster fly glue traps such as the Giant and Spider Web models.
Buying tip: place glue boards flat along walls and behind appliances for crawling insects, and hang fly spirals or bands where flies gather, for example near windows. Prices range from €1.15 to €42.45.
