Apply a broad 15 cm pressure bandage over the bite site as soon as possible do not take off clothing, as the movement of doing so will promote the movement of venom.

Keep the bitten leg still. Elasticized bandages are ideal, but any flexible material may be used. Clothing, towels etc. Panty hose have been successfully used.

Note: Bandage upwards from the lower portion of the bitten leg. Even though a little venom is squeezed upwards the bandage will be far more comfortable, and therefore can be left in place for longer if required. Apply a splint to the leg. Any rigid object may be used as a splint. If the bandages and splint have been applied correctly, they will be comfortable and may be left on for several hours. They should not be taken off until the patient has reached medical care. The doctor will decide when to remove the bandages.

If venom has been injected it may have an effect very quickly when the bandages are removed.

It's just that the microbes that cause those diseases can't survive our current climate, Currie says. Many people are familiar with bloodsucking insects, vampire bats and even sea lampreys, but here are some bloodsuckers you may not have heard of:.

With black flies, while the adult females may feed on larger animals like us, the larvae are an abundant food for other aquatic animals, Currie says: "And so without them we certainly wouldn't have the fish that we'd like to go fishing for. It feeds waterfowl and plays a really important role in our northern ecosystems.

Obviously, leeches have been important in medicine - they're still used to relieve blood congestion after surgery to reattach fingers and toes, and their powerful blood thinners were key to making the first human kidney dialysis possible in , Kvist says.
