Ants in Plastic Compost Bin

I have ants in my plastic compost bin.  When I tried to take the door at the bottom of the bin off to dig out some compost they were everywhere...  Will the nematode work if I water through the compost bin from the top?  If not do you have another suggestion?

Many thanks

Thanks for your e-mail.

The ant nematodes do not kill the ants but disperse them to other areas, watering them in from the top may drive them out but there is a danger they could return. You may need to apply more than once and water in thoroughly after applications.

I would also suggest applying some Agrothrin ant powder around the base, top and door to deter new ants entering the compost bin. I hope this helps.
