The general consensus is that it is not possible to build a completely insect-proof home. Conservative estimates suggest there are 100 different types of insects in every home and there is no effective method at keeping them out completely. Because, even if you manage to build a bug-free home, they are likely to enter with you on your clothes or shopping bags.

The good news is that most insects are completely harmless and you’ll never even know they are there.
Of course, that doesn’t mean you shouldn’t try to build an insect-proof house. After all, while most are harmless look at the damage that some can do, such as termites. If you decide to try, here are some of the most important considerations
Insects will find it easier to get through wood than metal or brick. That means you need to choose brick or metal to build your home. This doesn’t just make it harder for insects to get into your home, it will make it less appealing.
Metal homes are also very cost-effective to build and rapidly becoming a popular choice.
Old houses were built on mud, effectively allowing the insects direct access to the home. Modern ones usually have concrete foundations and this is an important step if you want to keep the insects out. A solid concrete base will prevent insects from entering your home. Providing the brick or metal is joined to the foundation and sealed properly there will be no entry points for insects.
The Weak Joints
The weak areas in any home are the windows, doors, and plumbing. This is where you’ll find small gaps that allow insects in. You need to make sure your windows and doors are completely sealed in position and brushes or foam are surrounding them to ensure they close tight and an insect can’t get through.
Of course, this also helps to insulate your home and reduce energy bills.
Alongside the doors and windows, you need to consider your plumbing. There will be tiny gaps around the plumbing pipes that need to be sealed to ensure the insects can climb in. It is also worth considering the inside of the pipes as this can be another option for insects. You’ll need to put a mesh in the pipe that allows water through and prevents the insects from coming up the pipes.
The mesh should be positioned where you can easily remove and clean it, you will need to do this periodically.
Even if you have designed a house that insects can’t get into, you will be going in and out regularly and insects can piggyback their way into your home. The only way to avoid this is to use an airlock on all entry points.
As this isn’t really practical you simply need to ensure you have a regular cleaning schedule that picks up any insects which do make it in.
