Pixelated Visual Attractant for Housefly Trapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fly paper traps are inconvenient to install and less effective due to their design, which does not utilize the visual attractants of houseflies, leading to inefficient pest control and potential health and environmental concerns with chemical insecticides.
Innovation Solution
A visual attractant system using a substrate with pixelated patterns and colors reflective in specific wavelength ranges to attract houseflies, combined with adhesive for trapping, and optionally incorporating images of insects to enhance attraction, is integrated into a sticky tape or pillar design for improved effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional fly paper strips are hung from the ceiling, then the sticky substance can trap flies, but the installation is inconvenient and requires high ceilings or ladders
Solution Approach 1:
The fly paper is segmented into multiple shorter strips that can be attached to various surfaces including walls and windows, eliminating the need for long strips that require ceiling installation
Solution Approach 2:
The fly paper can be attached to vertical surfaces (walls, windows) in addition to horizontal surfaces (ceilings), expanding the deployment dimensions and making installation more accessible
2Productivity
If conventional fly paper is deployed, then it can trap flies that land on it, but most of the deployed tape is in regions sparsely populated with flies
Solution Approach 1:
The fly paper incorporates localized visual attractants (blue and green regions) at specific positions to concentrate fly attraction to those areas, making the entire deployed area effective rather than relying on random fly distribution
Solution Approach 2:
The fly paper uses specific color patterns (blue and green regions) that match fly visual preferences to actively attract flies to the trap location, rather than relying on passive trapping
3Ease of operation
If conventional fly paper is removed from its container for hanging, then the tape can be deployed, but the sticky substance gets on the user's hands
Solution Approach 1:
A release liner or protective coating acts as an intermediary between the sticky substance and the user's hands during deployment, allowing easy removal without direct contact
Solution Approach 2:
The fly paper is provided in pre-cut strips or segments that can be easily handled and deployed without manipulating the entire roll, reducing contamination risk
4Productivity
If chemical insecticides are used to combat houseflies, then fly populations can be reduced, but resistance develops and health and environmental concerns arise
Solution Approach 1:
The patent replaces chemical insecticides with a mechanical/physical trapping system using sticky substance and visual attractants, eliminating chemical exposure while maintaining pest control effectiveness
Solution Approach 2:
The fly paper uses disposable, non-toxic sticky traps that can be easily replaced, avoiding the need for persistent chemical insecticides and reducing long-term environmental impact
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The visual attractant system significantly increases the catch rate of houseflies by leveraging their phototactic behavior and visual sensory preferences, improving the efficiency of pest control while being non-toxic and easier to deploy.

AI summary
A visual attractant for attracting a target insect include a substrate having a pixelated pattern portion defined by a plurality of blocks having a characteristic dimension that is within an order of magnitude of the size of the target insect. The plurality of blocks are colored to be highly reflective in a wavelength range selected to attract the target insect. A background portion is lighter in color than the pixelated pattern, to contrast sharply therewith. The blocks are clustered on the substrate such that most of the plurality of blocks define one or more irregular elongate streaks on the substrate. The pixelated pattern may be applied to a strip or to a pillar device, which may be adhesive.
