Bait Station With Nested Reservoirs For Ant Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current insect bait stations are inefficient due to their complex design, high cost, and inability to effectively manage free liquids, leading to leakage and spillage issues, and have limited success in ant control as they do not account for the behavioral characteristics and nutritional needs of target ants.
Innovation Solution
A bait station with multiple compartments and entryways designed to accommodate different bait types, including sugar, protein, and lipid baits, featuring a housing with a cover and tubular entryways that minimize leakage and maximize the attraction of forager ants, allowing for the distribution of toxicants throughout the ant colony.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gel formulations with high water content are used to accommodate insect feeding preference and control efficacy, then bait effectiveness is improved, but leakage and spillage issues occur due to free water
Solution Approach 1:
The patent employs a nested reservoir system where an inner reservoir containing gel bait is placed within an outer reservoir. The inner reservoir is designed to be removable and can be completely filled with gel formulation. This nesting arrangement allows the gel bait to be contained securely while minimizing free water exposure, preventing leakage and spillage during storage, shipping, and display.
Solution Approach 2:
The patent utilizes a flexible liner or thin film barrier within the inner reservoir to contain the gel bait formulation. This flexible shell prevents direct contact between free water and the external environment, effectively preventing leakage while maintaining the gel's water content for insect feeding preference and efficacy.
2Productivity
If multiple bait types are provided to meet different nutritional needs of ants, then ant attraction and foraging activity are improved, but device complexity increases
Solution Approach 1:
The patent divides the bait station into multiple separate reservoirs, each containing different bait types (e.g., protein-based, carbohydrate-based, lipid-based gels). Each reservoir is independently designed with the same simple nested structure, allowing easy assembly and removal. This segmentation enables offering multiple nutritional options to attract diverse ant species while keeping each individual component simple and manageable.
Solution Approach 2:
The patent creates a universal bait station design where the same nested reservoir structure can accommodate various bait formulations. The removable inner reservoir serves multiple functions: containing gel bait, allowing easy refilling, enabling complete drainage of free water, and facilitating cleanability. This multi-functionality reduces overall device complexity despite offering multiple bait types.
3Ease of operation
If open entrances are provided for insect access to bait, then bait accessibility is improved, but free liquid leakage occurs during production, storage, and display
Solution Approach 1:
The patent uses a nested reservoir configuration where the inner reservoir containing gel bait is placed within an outer reservoir. The inner reservoir is designed with an open top entrance for insect access but is completely filled with gel formulation, eliminating free water. This nested structure allows insects to access the bait through the open entrance while preventing free liquid leakage during production, storage, and display.
Solution Approach 2:
The inner reservoir is pre-filled with gel bait formulation before being placed in the outer reservoir. This preliminary action ensures that no free water is present in the inner reservoir, preventing leakage during subsequent handling, storage, and display phases while maintaining open entrances for insect access.

AI summary
An insect bait station, for example an ant bait station, for deploying a toxicant includes a housing with a body portion covered by a cover. The body portion includes first and second reservoirs. Entryways having a converging outer portion and an upright tubular portion provide insect access into the housing. The upright tubular portion extends from the converging outer portion, through a bait in the second reservoir. An entry port is provided in the tubular portion above the bait. A first bait is disposed in the first reservoir and a second bait is disposed in the second reservoir. For example, the first bait may include a protein-based food and a pesticide, and the second bait may include a sugar- or lipid-based food with or without a pesticide.
