Honestly and seriously added as a "blatant counter example":

"What is the most effective way to get icecream ?"

I need to have 5 cups of different tastes."

Answer:

"The most effective /efficient way might be to invest some money, go to the icecream shop and ORDER.

Principle ("staining mechanism"):   

First step:  "Here Order - and money, 

Second step:   Then:  you are given eventually icecream - if you are lucky  the right variety - and eventually a napkin too...  "

If you are a "starting beginner":  you must know that experts have knowledge but they for sure were not able to acquire that knowledge standing on their head but by hard work.

Experts perhaps therefore are willing to distribute their knowledge to others if the way of communication and "requesting valuable information"  is either without obligation, or for information only - without responsibility or - more successful -  rather in a familiar / more passionate fashion than found with your request above (admitting that this your request is "short", "precise on the spot", but far to unprecise / superficial.  

Honestly: 

If you are an advanced beginner or still advanced / skilled learner or student (or even instructor....   we unfortunately don't know more about your person and / or your affiliation)  you should be able to conduct a  literature search independently or at least read books specialised on the matter (e. g.  perhaps titles like:  "   Histology of Cestoda / Trematoda, helminthes, parasites   " ,  etc.etc.)

 - in relation to the techniques/methods one wants to use, searching also for :

Classically: "histological -histochemical stain(s)"  or  more sophisticated: "immunohistochemical-immunocytochemical localization  /staining",   "great morphology" only, or, general localization within tissues.....

Then you would have found at least also 'Acetocarmine' staining, but, as a side effect, would have learned also that one has to specify the technical procedures you are dealing with (or you are about to deal in the future):

Native (intravital) staining (transferring parasites eventually also into whole mount preparations),

Staining sectioned material (e.g. from paraffin-embedded  or even frozen sectioned parasites) - permanent slides,

eventually species-dependency and optimal staining of /for parasitic subtextures, therefore which species you are examining / going to examine?

(which specific specimen preparation protocol - prior to staining )    and so on...

My special hint : Start with: TABLE 1 in:  Bruno et al.: "Guide to the identification of fish protozoan and metazoan parasites in stained tissue sections"  (2006).

cf. Subsection: TECHNIQUES (p.3.):   "........   Because of the rapid and continuing development of these staining techniques for the identification of parasites, the reader is referred to sections on specific parasite groups in this review, and is advised (to) search the current literature on specific parasites for the most up-to-date methodology.

Table 1. Examples of special stains used for identification of parasites in histological sections. PAS: periodic acid-Schiff

"Guide to the identification of fish protozoan and metazoan parasites in stained tissue sections". Available from: https://www.researchgate.net/publication/6911910_Guide_to_the_identification_of_fish_protozoan_and_metazoan_parasites_in_stained_tissue_sections 

Furthermore I suggest you search [FULL TEXT SEARCH!]  in the existing huge ResearchGate archives in e. g. finding  (upper Menu line to the right, find field:)  "SEARCH", click (into)  the "down pointing arrowhead", choose "QUESTIONS" , insert any search phrase, known "title" ,  keyword or keyword combinations, leaving at least two or three empty spaces in between, so in this your case, e.g: 

|  cestod*  parasite*  staining   |   [NB: copy and paste whole phrase in between the two vertical lines/bars]     which creates after some second the/an URL: 

https://www.researchgate.net/search.Search.html?type=question&query=cestod*+++parasite*++staining+

and there you can see that "Questions (25+)" are found - most of them might interest you.

Cool,  start and have fun....in reading, and afterwards, in theoretical considerations, establishing your specific protocol, and finally -successful  practice & exercise.

Have a nice weekend, regards W.M.
