I can supply suitable rodenticide DIY products for your rodent problem delivered to your doorstep along with some proper guidance on the best usage. These products are classified as for ‘amateur usage’ only. The products I deploy during my professional visits are not available by law to the general public, sorry. Because of this, these products are around 25% of the strength we professionals are allowed to use. The nett result is that you either have to feed them more or eradication takes longer – Ian Thomas.
