Are mosquitoes a problem in Egypt in the evenings?

Mosquitoes are indeed numerous in the evenings. Travelers recommend bringing a Fumitox-type fumigator device, mosquito spray, and anti-mosquito bracelets — run the fumigator all night, spray your legs, and wear the bracelet on your wrist.

Bites from local mosquitoes heal quickly — by the next day there's barely any trace, unlike mosquito bites back home (e.g. in the Urals), which can bother you for a week.

Hotel grounds are treated with mosquito repellent spray, but it doesn't fully eliminate them. Sitting on a balcony for an hour in the evening can result in quite a few bites.

Mosquito bites often go unnoticed at the time — the itching only starts later back in the room. Children seem to get bitten more frequently than adults.

The mosquito situation varies from person to person — some travelers barely notice them, while others come back with visible bites. Swarms bad enough to drive you indoors are uncommon, but individual bites are a real possibility.
