Segmented Paraffinized Rodenticide Bait with Pulpy Core
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rodent control methods face challenges such as environmental pollution, risk to non-target organisms, and reduced effectiveness due to issues with palatability and fixability of existing solid and pulpy baits, including paraffinized and pulpy products.
Innovation Solution
A combination of a shaped paraffinized solid bait with a pulpy bait, where the pulpy bait has a higher rodenticide concentration and the solid bait has a lower concentration, ensuring rodents consume the pulpy bait for a lethal dose while minimizing human and environmental exposure, with a fixable design to prevent bait removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If paraffinized solid bait is used, then fixability is improved, but rodent acceptance deteriorates
Solution Approach 1:
The bait is divided into two distinct parts: a paraffinized solid outer shell that provides fixability and structure, and a pulpy inner core that provides high rodent acceptance. This segmentation allows each part to fulfill its specific function without compromise - the solid exterior anchors the bait while the soft interior attracts and retains rodent interest.
Solution Approach 2:
The invention combines two different material types (paraffinized solid and pulpy substance) into a single composite bait structure. The paraffinized portion provides mechanical stability and fixability, while the pulpy portion provides sensory attraction and palatability, creating a composite that achieves both fixability and high rodent acceptance simultaneously.
2Ease of operation
If pulpy bait is used, then rodent acceptance is improved, but fixability deteriorates
Solution Approach 1:
The pulpy bait is nested within the paraffinized solid shell, creating a layered structure where the soft, attractive core is protected and held in place by the rigid outer shell. This nesting arrangement allows the pulpy interior to maintain its high acceptance qualities while the solid exterior provides the necessary fixability to the substrate.
3Reliability
If high rodenticide concentration is used, then effectiveness is improved, but environmental pollution and human exposure risk worsen
Solution Approach 1:
The rodenticide concentration is distributed non-uniformly throughout the bait structure, with higher concentrations localized in the pulpy inner core and lower concentrations in the paraffinized outer shell. This local quality differentiation ensures that rodents receive a lethal dose when consuming the inner core, while the outer shell provides protective barriers that reduce environmental dispersion and human exposure risks.
4Reliability
If conventional bait is used, then rodent control is achieved, but bait removal by rodents worsens
Solution Approach 1:
The bait structure is designed with a dynamic consumption pattern where the hard outer shell remains fixed on the substrate while the soft inner core is progressively consumed by rodents. This dynamic design allows the bait to maintain its anchoring function throughout the consumption process, preventing complete removal while enabling effective rodent control as rodents work to access the attractive interior.

AI summary
The present invention relates to a device for controlling rodents. More specifically, the present invention relates to a device consisting of a combination of a solid and a pulpy bait (commonly known as 'fresh bait' or 'pasta bait' in rodent control practice), wherein the solid part is a shaped paraffinized rodenticide bait with a rodenticide concentration which is lower than or equal to the rodenticide concentration of the combination and contains the pulpy rodenticide bait with a rodenticide concentration which is higher than or equal to the rodenticide concentration of the combination. The rodent control device according to the invention has an enhanced acceptance by the rodents and can preferably be fixed by a hole formed in the solid part preventing the rodents to take it away. Furthermore, the present invention relates to the preparation and use of such rodent control device.
