Which ingredient may be included in some repellents and may be combined with taste repellents such as capsaicin?

• A. Egg solids
• B. Garlic powder
• C. Water
• D. Sugar

Answer: (A)

Egg solids serve as a base or carrier in some repellents, providing a protein-rich matrix that helps the product form a durable coating and keeps the active capsaicin in place so the deterrent effect lasts longer. The capsaicin acts as a taste deterrent, and having a solid carrier enhances the delivery of that cue to the animal. Other options don’t offer this practical base: water would dilute and do little to stick to surfaces, sugar could attract pests, and garlic powder is mainly an odor/tavorant but doesn’t function as a binder or carrier like egg solids. So egg solids best fit the role of a component that supports a capsaicin-based repellent.
