Yes. Not recommended in summer for bigger birds like pigeons.

It's better to use it when temperatures are low, as pigeons can sleep it off. You could get the paste version and warm it and soak pigeon pea in it. Use untreated pigeon pea to prebait so the pigeons get familiar with being feed. 

It doesn't bowl them quickly, maybe 10 - 20 min, so you would need to remain onsite to pick up effected birds and either cull or put them somewhere cold to die.

Pea is too big for sparrows and non target birds. 

You could try using a cage  to trap them, but this would involve multiple visits.

An explosives expert friend of mine was given the chance to get rid of a load of rooks in the Wairarapa about 20 years ago. He discovered where they were roosting when on the farm and he rigged the old elm with Powergel and det cord, with the ignition box fed out for 100yds (to a drain).

When the farmer told him the rooks were back, he went over that evening and from the drain, blew the tree (with rooks) to bits!!!!! 

He reckons he got 30+ rooks that way!  Wish I'd been there for that one!!!!

Officially he was blowing up old tree stumps - or so the Police were told beforehand!!!!! 

Food for thought perhaps?!!!!! Ha!

Made me appreciate that I don't want that type of attention.

This is a classic example of what not to do
