Older bites are sometimes troublesome; the damage is sometimes already done but ZapIt can help to soothe the itch and avoid the scratching which can make things worse and cause infection. Recent results of a clinical study carried out at the London School of Hygiene and Tropical Medicine confirms the therapeutic benefits of Zap-It!on mosquito bites by reducing histamine flow, and therefore the itch, whilst stimulating the capillaries into flushing out the toxins. When you get bitten, you of course get the urge to scratch the bite. Unfortunately when you scratch a bite, the area gets flooded with histamine. This causes swelling, incessant urges to scratch and a risk of damaging the skin’s surface, which could lead to infection.

How does Zap It work? 

To zap an insect with a 3-layer mesh zapper, the insect must touch the mesh in the middle and one of the other mesh layers. With a single-layer grid, the insect needs to touch 2 wires on the mesh to be electrocuted.
