This liquid is thoroughly repellent and poisonous, but for good measure the resins in the liquid can turn solid when exposed to air and seal a small insect in a tomb.The squirt gun stores its chemicals in a network of canals in the leaf. When an insect bites a leaf canal, the liquid squirts out as far as 1.5 metres, drenching a small insect in deadly secretions.
