Is Pyranha effective against any other insects?
Yes. Almost all insects are killed or repelled effectively by Pryanha. The only insect we know that is unaffected by Pyranha is the wood-bumble-bee. This particular pest requires the use of a good sledge hammer to kill. A timed spray after dark kills or repels spiders, roaches, roosting wasps, mosquitoes and all other insects. Your building stays cleaner when it is insect free.
