pyrethrin

[primrose 4]

i know pyrethrin will get insects agitated before they succumbe but seeing we offer a greener alternative to pest control but e.g wasps or bed bugs if the client is kept away it should be safe?

[Matt 160]

Safe?

 

Possibly safer.

 

It all depends on how you define the hazard. Is the risk of a sting, or a reaction from a sting more or less than the risk of an application of something that kills them quickly without agitating them?

 

As for bedbugs, don't forget that they are becoming increasingly tolerant to insecticides. Treating with something that agitates them (like a flushing agent) would potentially make an infestation much worse.

 

How do you define 'green' ?

i dont know if i got this correct but are you saying keep away from pests instead of using pyrethrin insecticed?or keep them away during or after treatment? you have time restraints before re-entry anyway into treated areas without ppe.as mat says how are you defining hazard.risk assessment before treatment,nobody but operative with ppe should be in treatment area until time restraints elapse unless authorised and given required ppe with qualified personell present.what exactly is your question.

sorry i did not make myself clear after the treatment has been done i.e wasp nest in an air brick how long would it be so the client will not get stung by agitated wasps because as we know ficam d does not get them agitated i hope this helps

I don't think there are any pyrethrin based powders available anymore. Coopex used to be OK, but call backs were more common than with Ficam.

 

The point I was making was that the advantage of using Ficam is that clients are less likely to be stung; therefore your risk assessment should show that you've minimised the hazard of stings. Using something that agitates would not do this. In other words, the hazard from stings is greater than the hazard from Bendiocarb.

 

Using pyrethrin on bedbugs would be a really bad idea.

 

Do you really think there is a demand for this type of service with insects? If so, OA2KI is a much better and 'greener' option.

most powders have been made synthtic ie permethrin is a synthetic copy of pyrethrin,but if your using this expect aggitation to insects which will cause wasps to go a little crazy,synthetic copies offer same reactions but are classed more friendly to mammals than beniocarb,so bats are at LESS risk,ground nests are safer to treat if cats abound as cats fall victim too bendiocarb with liver damage being caused,ant treatments and such with bendiocarb wettable powders can be problems as cats rub themselves along walls and lay at wall/floor junctions of houses and walls and ingest during there self grooming,risk assessment is the key,fish ponds suffer bad from carbamates but then again any pesticide,permethrin is not free of risks so its risk assessment is again the key,if treating with permethrin to restrict mammilian contact expect aggitation,so risk assess ie windows closed and area access restricted,i always advise 24 hour exclusion verbal and written and usually treat at dusk when cooler,but that can be a tall order sometimes,and also it does not stop aggitated wasps leaving restricted area to sting neighbours.ficam or similar correctly applied is better for less agitation with definite sting reduction as matt says,there are pro's and con's to most things,your assessment will help you decide where the axe is to fall,hopefully not on you.i think you need to look at each situation differently for the risks if GREENER is your goal cos risks come in many forms and a solution may be a problem elsewhere.take care now..
