Affordable, Innovative Grapefruit Method Eliminates Slugs Naturally
In the ongoing battle against garden pests, a surprising ally has emerged – the humble grapefruit. This citrus fruit, often discarded after consumption, can be transformed into an effective slug trap that is both eco-friendly and pet-safe.
**How Grapefruit Slug Traps Work**
The concept is simple. Placing a hollowed-out grapefruit half near plants attracts slugs with its aroma and moist interior, providing a hiding place or trap that can be collected and disposed of the next morning.
**Effectiveness of Grapefruit Slug Traps**
While easy to set up, the effectiveness of grapefruit traps is generally considered moderate. They do not significantly reduce the slug population over time and require regular maintenance – you must check and clean the traps frequently. However, they are less visible than beer traps, making slug removal easier by concentrating slugs in one place.
**Comparing Grapefruit Slug Traps to Other DIY Repellents**
When compared to other DIY slug repellents, grapefruit traps fall somewhere in the middle. Methods like beer traps, copper tape, or nematodes are generally more effective at reducing slug numbers. However, grapefruit traps can be a useful supplementary method, especially when combined with other DIY repellents.

Interestingly, grapefruit has a larger interior than other citrus fruits, making it more effective for trapping slugs. To make the trap even more effective, some gardeners recommend cutting a little entry for the slugs in the side of the peel when it is placed face down. If placed cup-side up, slugs may have difficulty getting back out and can be easily disposed of in the morning.
