We too often see niche products like TangleTrap struggle to keep a business going.
Some suggest chemicals are just so much easier to use. Sarcasm aside, growers need "sticky stuff" to trap out maggot fly, occasionally create trunk barriers, and other homemade options on the insect trapping front. We used to heat the gallon can of the pest barrier formulation to dip red wooden balls by the dozens upon dozens to trap out AMF. Today I indeed "trowel" this denser TangleTrap product onto Red Delicious apples for the same purpose (hanging far fewer traps on select trees rather than perimeter trapping as in the past). I just checked the
Great Lakes IPM website -- my first source for insect monitoring supplies -- and they seem to have the full line of TangleTrap products in stock. Of course, a phone call may reveal otherwise.
