Hi all,
At the end of my tether and now I am turning to chemical warfare, so can anyone tell me which pesticide to use and were to buy it, to get rid of the little blighter's.
Yours Mrs Bulldog.

Go into Soldebre, Tortosa, and ask them there, what you should use.

Many thanks Rita and Bunter, very informative but thought I would try Soldebre but what are thrips and the poison called in Spanish.
Yours Mrs B. 

They are called Los trips

Just copy one of the products below and look for the same ingredients they are a worldwide bug so the same methods kill them.

Thrips DO bite humans.

If you have ever been bitten by something but look down to find nothing there, you could have been bitten by a thrips. (Thrips is the singular and plural form). Measuring in at a minute 1/32"-1/8" long, thrips are difficult to immediately see.
Why Do Thrips Bite?

Thrips do bite humans but not as a defence mechanism as with many other insects. Thrips bite as a means to discover food sources. Though some thrips species will feed on other thrips, insect larvae, and mites, most are phytophages, feeding on plants and plant parts. So soon after a thrips bites you, it will discover that you are not a food source and move on.

Thanks again, I am finally sorted and chemical war has begun with what the other half calls his weapon of mass destruction. Hope Tony Blair does not hear about it.
Yours Mrs Bulldog.

Don't worry.  Tony B. Liar (The Middle East Peace Envoy) is much too busy organising peace in the Middle East.  What wonderful work he has been doing.  Just look at the results!!!
