The little strip of flea collar has been 100% effective... I just have to remember to replace it yearly, and that just might be a problem!
The only place the critters can come in is at the bottom around the hinge. Cut a pc of screen and attach it to the frame and tape it to the door and cover that opening or just make a screen to fit inside the wh housing flange.
Another idea is to add a sponge weather strip along the bottom of the door to seal the hinge area against the housing.
As for the latch, remove the spring loaded latch and put a metal disc (large enough to cover the hole in the door) under the latch & in front of the metal angle that holds the mechanism
