VENOMOUS
The Northern Pacific Rattlesnake is lethaly venomous. A bite from one of these snakes can result in death, though death is very rare (death from bees and wasps are far more common.)
Do not attempt to handle this snake without the proper training. If this species is a problem in your yard, you can take action to reduce the liklihood of a bite to your family or your pets:
- Remove debris from around your property. Debris attracts rodents and snakes.
- If you have livestock, clean up any spilled feed immediately and store feed in sealed containers away from areas where your children and pets play. Spilled feed attracts rodents which attract snakes.
- Remove weeds and overgrowth, keep lawn well cut.
- Install a silt fence around the areas where your children and pets play.
Some people like to obtain California Kingsnake (Lampropeltis getula californiae) and release them on their property. Please do not. The California Kingsnake does feed upon the Northern Pacific Rattlesnake, but the California Kingsnake is already widespread throughout Shasta County. Releasing additional specimens in your area will simply mean some have to die (likely the ones you release) because there are already as many as the habitat supports. It is also against the law in California to release wildlife without express written permission from the Department of Fish & Game.
If You Are Bitten
If you are bitten, it is important not to panic and to remain calm. Do not try to suck the venom out, do not cut the wound, do not apply a tourniquet, do not apply heat or cold packs. Keep the bite below the heart and immobilize the bitten area. Remove any rings or bracelets, the bite will cause swelling.
