Tri-tec 14 insecticde - is it any good pls?

[RLT19]

Hi
just seen an ad for this - looks good but is approx £35. Normally use home made fly sprays as have given up on the manufactured ones!
I am convinced we have more bugs around now due to the mild & weird weather we get in this country - we had highs of 19 here today & only 7th April - I'm sorry that wasn't April weather when I was a child!
Anyway - anyone know if this spray is any good - it is for sale on horsehealth
or alternates please! thanks in advance
Have just found the ingredients - if anyone knows anything about fly sprays!

Great fly spray - in fact the best I've ever used and it lasts for 10 days - make sure you re-apply if it rains though. Also has sunscreen in which is great for days like today bring on a long hot summer I say

Bought mine from here as it is cheaper:
