Protect silage bales from rats

Protect silage bales from rats

Thursday, July 8, 2010

Baiting the lower layers of round bale silage stacks is the best way to protect them from rat attack, according to Dr Jonathan Wade, technical director for UK rodenticide manufacturer PelGar International.

"When stocks are short it is even more important to protect the quality and quantity of silage that has been made, so keeping rats out of stacks becomes an even greater priority."

 "Rats love to burrow and nest in the bottom of silage bales - tearing their way through the plastic and settling inside. This lets in air which causes spoilage and encourages moulds that can contain listeria bacteria, which will make livestock ill if they eat it. This is why it is so important to protect the bottom two layers of a stack by baiting."

Dr Wade advocates the use of place-packs or waterproof sachets as the stack is being built, as this is the only chance to bait evenly across the site.

On the next layer one sachet every second junction is usually enough, unless future infestations are expected to be high, in which case every level of the second layer should be baited, he adds.

"For a stack 20 bales long, five bales wide and four bales high, our recommendation is 72 sachets of Roban on the bottom layer and 20 on the second," advises Dr Wade.

Any uneaten bait should be removed as the bales are used, and disposed of according to label guidelines.
