Mosquitoes may not carry malaria but can cause irritation and infected bites. Using DEET-based insect repellents will prevent bites. Mosquitoes also spread dengue fever.
Bees and wasps only cause real problems to those with a severe allergy (anaphylaxis). If you have a severe allergy to bee or wasp stings you should carry an adrenaline injection or similar.
Scorpions are frequently found in arid or dry climates. They can cause a painful bite, which is rarely life threatening.
Mercifully, Iran doesn't seem to suffer too badly from bed bugs, though occasionally they do pop up (as opposed to appearing - who's ever seen one of the critters?) in hostels and cheap hotels. They lead to very itchy, lumpy bites. Spraying dubious-look-ing mattress with insecticide will help get rid of them, or use a sleep sheet.
Scabies might also be found in cheap accommodation. These tiny mites live in the skin, particularly between the fingers. They cause an intensely itchy rash. Scabies is easily treated with lotion available from pharmacies; people who you come into contact with also need treating to avoid spreading scabies between asymptomatic carriers.
