How to use Iron Phosphate in Gardens

Molluscs such as snails and slugs are harmful to plants. They not only feed on plants but leave slime trails on them from their mucus-secreting muscle. Getting rid of snails and slugs from your garden is possible by using poison baits. However, many people use a natural control such as iron phosphate in order to get rid of these pests. Two of the most popular snail and slug bait products are Sluggo and Escar-Go which also contain iron phosphate. It is safe to use iron phosphate as it does not harm pets, humans, fish, birds or even insects.

    When a snail or slug eats iron phosphate, the iron phosphate gets in the way of calcium metabolism in their gut. As a result these pests stop eating immediately. They eventually die after 3 days or even a week. Remember that it is applied to the soil as a pellet which contains bait. The bait attracts the snails and slugs towards the pellet, eventually luring them to eat it.

    When a snail or slug consumes iron phosphate, they get disposed without creating a mess. You will not see your plants bitten again after applying it. In addition to this, you will not see dead bodies of these snails and slugs. This is because they travel to other scheduled places before dying.

    Unused iron phosphate
