brown garden snailCornu aspersum is native to the Mediterranean area and western Europe, but humans have spread it worldwide. This is one of the most common pest in gardens and in agriculture. They feed above ground on organic material and vegetation. Feeding usually takes place during night time at temperatures of 5 - 21ºC. It feeds on numerous types of fruit trees, vegetable crops, garden flowers, and cereals. It also is an omnivorous scavenger that feeds on rotting plant material and on occasion will scavenge animal matter, such as crushed snails and worms such as earthwurms.

Each snail can lay up to 120 eggs. In a year it may lay six batches or so. Depending on soil moisture, eggs can hatch in as little as two weeks, releasing a wave of hungry young snails. The young snails take one to two years to reach maturity.

use orchard agrikems sluggem to control armadillidium vulgareArmadillidium vulgare may reach a length of 18 millimetres and is capable of rolling into a ball when disturbed; this ability, along with its general appearance, gives it the common name pill-bug or roly-poly. Armadillidium vulgare is able to withstand dry conditions, and is restricted to calcareous soils or coastal areas.

It feeds chiefly on decaying plant matter, but also grazes lichens and algae from tree bark and walls. It is is generally considered a organism beneficial to agricultural practices. Because it has the ability to feed under the soil's surface, it can cause severe agricultural crop damage during germination of Canola seeds. The carbaryl containing snail bait pellet SLUGGEM® should be used to address isopod problems.
