Is there a screen behind the louver that prevents insects from coming and going?

No screen but the perforated Louver does not allow insects in. A well thought out design

When we used our Wenzel screen room, we did not have any trouble with insects coming in. I actually don't remember the mesh drains, so they must not have been a problem.

No, it doesn't have a screen. Easy enough to add one from Home Depot if you go into the gutter section and buy a small quantity of bendable screening. I used what I'm referring to on my downspouts which you can bend into shape if needed and this way you'll always be prepared if your having issues with dirt or debris.

No - it is a heavy-duty mesh. Long lasting that keeps out big bugs, but not the no see ums.

The mesh on the fly screen is VERY small. I don't know that we have used this tent where there are no-seeums, but I have been around them and I don't believe they could get through this tent's mesh.

Yes. It is a summer tent so the top screen is intended as ventillation. With the fly installed it allows for fresh air without a breeze. Not a 4 season tent by any means. I would imagine you could put a towel or piece of material over the top vent if you really wanted to cover it.

yes, by having the water entered through a bug screen inlet. I drilled four,4 inch holes in the top of the barrel, then place bug screen over the holes to keep mosquitoes out. If you look on the Internet ,you will find many examples of how to keep mosquitoes out of the water barrels.

They have a screen inside...look at the photo---your can see lines of the screen through the louvers

Yes it will as long as it is closed. When the wind blows the louvers will open, so it is possible for a bee to enter. I have thermostatic control fan mounted behind the louvers and when the fan is on nothing could enter because the fan is really strong. If I did not have the fan i could have a screen behind the louvers which would keep out insects. It seals out water and has weatherstripping on the individual louvers which seals pretty well.

The screen is a nice one but since I don't have anything planted in the planter, water collects there. I will probably drill holes in the planter so water doesn't collect there but I would imagine mosquitoes will prosper there if I don't do something about it.

There is regular screen mesh on the inside. The louvers are very close together. When you place it in your window, put it with the louver side on the outside and the louvers facing down. The screen side should be on the inside. If you place them in your windows this way you won't get any rain coming in. I put them in my windows as soon as the weather starts getting nice and take them out in very late fall. They keep my attic nice and ventilated. Make sure you buy thermal king. They are very well made. Hope this helped.

Any insects that goes inside the screen will be killed, unfortunately.If they don't go & just fly around it, they won't get killed, ;-)

I bought it over a year ago but as I remember it didn't. The louver would be an optional buy. I actually used a strong aluminum mesh to cover the fan to protect animals and people from hurting themselves.

I sprayed the screen with Off or some other bug repellent and it did an adequate job of keeping out no-see-ums. Think most of the bugs came up from the ground, so as the other respondent indicated, it's important to have the tent well staked and the bottom perimeter kept down (I used boards). I used the tent primarily as a painting shed to keep bugs out of my freshly painted projects and it did a great job.

Holes are big enough for insects to go thru, but I keep my fan behind the screen in the window, so not a problem for me.

No. A bit of deet sprayed on the screen once in a while would probably solve that issue. Still, look around. This thing is not great. See my review.

The fan is designed to be placed in the window with the screen still in place to keep the insects out. It has a very narrow profile. We love these fans and have three of them.
