Standard Insect Waffle Fabric Lids - 32 oz Deli Cup Vented Lids (50 Count)

Professional-Grade Ventilation for Fruit Fly Cultures and Live Invertebrates

Keep your feeder cultures thriving and your insects secure with our Standard Insect Waffle Fabric Lids. These lids feature a specialized fine-mesh fabric center designed to provide maximum gas exchange while remaining completely escape-proof. They are the industry standard for maintaining healthy humidity levels without the risk of CO2 buildup or mold growth.

Superior Airflow and Security The breathable fabric membrane is specifically engineered to contain even the smallest Drosophila melanogaster and hydei fruit flies while blocking out external pests like mites or phorid flies. Unlike plastic-only vented lids, the waffle fabric allows for consistent evaporation, which is critical for preventing culture crashes and keeping your reptile feeders fresh.

Universal Fit and Bulk Value Each sleeve contains 50 lids, offering an economical solution for hobbyists and professional breeders. These lids provide a secure, snap-fit seal on most standard 32 oz and 16 oz deli cups. Whether you are culturing fruit flies, housing praying mantis nymphs, or storing bioactive clean-up crews, these lids provide the safety and ventilation your animals require.
