Slugs are known to thrive in damp and moist environments, and they are generally active during the nighttime, especially when the weather is wet. However, like all living organisms, slugs are also affected by extreme weather conditions, including temperature, humidity, and precipitation. Generally, cold weather is unfavorable for slugs, and freezing temperatures can prove to be deadly.
In high humidity weather, slugs can thrive, and the higher the humidity, the more active they become. The drying out and death of slugs can occur in prolonged drought conditions. The hot and dry weather can cause fatal desiccation in slugs. The most significant threat to slugs occurs when temperatures are high, and soil moisture is low, causing them to seek cover.
In addition to extreme weather conditions such as freezing temperatures, prolonged drought, and high temperatures with low moisture, several other factors can also impact slug populations. For example, heavy rainfall can cause flooding and wash away their habitat, while strong winds can dry out and kill them.
Slugs are sensitive to extreme environmental conditions and can be killed by a range of weather factors. Thus, it is essential to consider the weather conditions while protecting crops from slug damage. Measures such as the use of slug barriers, slug-resistant plants, and natural predators can also provide effective control of slugs under certain weather conditions. Therefore, understanding the impact of weather on slug populations can contribute significantly to managing these pests effectively.
