It was the opposite for me: liquid and local ones did not work, but our lamellar one helped.
Plates help a lot. You just need to insert the plate into the fumigator working from the outlet, and the insects will not disturb your sleep. When heated, the toxic components begin to evaporate, negatively affecting the bloodsuckers. Enough two fumigators per room. The plates were changed daily. The fumigator helps not only in Egypt, but in all countries where there are mosquitoes. So that mosquitoes do not eat you during dinner or an evening walk, I recommend plastic bracelets. One bracelet is enough for 4 days. The bracelet contains a container with a repellent and several sealed holes that you pierce them as needed. This option came up to our family, since you don’t need to smear yourself with something incomprehensible and splash yourself on yourself, don’t understand what.
