Worms in soil?

[loubylou]

Really not sure what to title the post!
Uva has moved house
Her worm burden has always been minimal, she has regular worm counts and is wormed for key worms (those that don't show in counts) throughout year. Last count was <50 and she has just had the winter wormer for encysted red worm (on direction from old yard owner) so would usually be ok til spring....

however, she has moved house, and has gone into a field that hadnt been poo picked, and previous horse was wormy (owned by an undesirable livery that has since moved away).

First thing I did was poo picked so that the field was clean before she went out. Horse has not been in the field for 2 weeks but poo was only picked up yesterday. Uva went out in it today. How long will the worms still be able to be picked up by her? Am aware it could be a while and am prepared to count and worm for the next few months as needed but just wanted some advice as to how long the worms will be in the soil for?

Thanks!

I think in the winter the eggs on the soil can live for months, its the really really hot summer months when they get killed off by the heat I believe

Worm eggs can survive for a long time, although some get killed by frost and some rely on other hosts to restart their cycle. If you have used Equest for your encysted strongyles then the horse will be protected for 13 weeks as the wormer is stored in body fat and further dosing is not recommended during the 13 weeks, tapeworm would also have been treated if you used Pramox, but I don't think the 13 weeks is relevant for tapeworm.
To be effective, poo-picking needs to be done straight away to stop the eggs being moved around the pasture by birds, rain etc. so you may have a while to wait to get clean pasture - unless you can find some sheep to cross-graze.

I would email Gillian at Westgate Labs for advice. Whenever I have moved a new horse on to my field I have asked her and she is always spot on with the advice she gives. ;D
