Best treating wood worm

Great value for money. I buy and renovate properties. I have used this treatment before on my other houses and always works really well and does what it says on the tin.

very good

Fantastic value for money, super fast delivery, easy to use

Money saver!

Arrived next day, simple to dilute and spray. Covered the whole loft (semi 3 bed) with 2 units and saved a fortune. Not only that I knew every timber was covered.
