Bed bug bites itch and develop into weal with pus-like formation (inflammation). This can cause frustration and stress, especially if you are allergic to the proteins in the insect's saliva. Some people develop severe allergic reactions to bed bug bites. In rare cases, people develop anaphylactic shock.
Bed bug bites on dogs can cause skin irritation, pink welts or spots on the skin, intense itching and even allergic dermatitis. They can also cause patchy hair loss, rashes, hives, blisters and even irritability or anxiety in the pets.
However, for people with a bed bug bite allergy, the reaction can be more severe. When a bed bug bites you, it excretes an anesthetic to numb the skin and prevent irritation, so that you do not detect the bite immediately.
In practice, the symptoms of an allergic reaction to bed bug bites can be relieved by taking an over-the-counter oral and topical antihistamine medication. They will reduce redness and inflammation. Besides, they will stop the affected area from itching. First, wash the inflamed bedbug welts with warm water and soap.
Prevent allergic reactions to bug bites. In fact, studies have shown these shots are 95 to 97 percent effective in preventing severe allergic reactions," Dr. Redding says. "It's an extremely effective therapy." However, he points out that venom shots are only given to people who have already had an allergic reaction to a sting or bite.
Black widow spider bites may cause stabbing pain in the bite area, but they can also be painless. Look for one or two red fang marks, redness, tenderness, and a nodule at the bite site. Severe muscle cramps, nausea, vomiting, seizure, and a rise in blood pressure may follow soon after. Get medical care immediately.
