Preventive measures would include: checking around the house for new hornet/wasp hives–and removing them; use of insecticides around eaves and overhangs to reduce nest promulgation; and use of Off or other products to reduce mosquito bites.

If your child has EVER had a large localized reaction to a bee sting regardless as to whethe you've had the child tested by an allergist–keep Benadryl elixir (for children) and Benadryl capusules 25-50 mg capsules avialable for immediate treatment of reactions to bee stings. If the child experiences signs of a serious reaction–the Benadryl will likely provide life-saving relief until you can get the child to emergency medical care.

If you know your child is allergic to bee stings–get the allergist, or PCP to prescribe an epi-pen and train you on the use to administer to your child.

Calamine lotion–is good for mosquito bites and rashs–hydrocortizone cream works faster in most cases–and dosen't leave a pink haze on the skin.
