Cockroach gels and baits are a common and effective form of cockroach control. These baits work well for all cockroach species but are particularly effective on German cockroaches. Cockroach bait is most often in the form of a gel in a syringe. With the use of the easy-to-apply syringe, the bait can be applied as small spots, approximately the size of a pin head, around kitchen cupboards, on the hinges, under bench tops, under and around the appliances including microwaves, dishwashers, fridge motors, electric jugs, toasters, etc. Some cockroach baits are also available in granular form.
