Health And Pest Issues With Drains

Drains are notoriously unhygienic. The reason why is simple. Dirty water, sewage and food particles all go down into drains. What this also means is that drains can often be a source of pest issues. In this post, we’ll go over some of these issues as well as what you can do about them.

Why drains are such a source of pest problems

The biggest problem with pest issues and drains is that they are often used as an entry point for pests. In this case, it’s usually pests like rats and cockroaches. Cockroaches love drains because it provides them with a dark, warm, wet place to live. On the other hand, it’s not a myth that rats use drains as a means to travel around and also as a way to get into houses.

Another serious problem are drain flies. These are small, dark flying pests. They live and breed just inside the mouth of your drain. They are primarily attracted to the food debris that coats the inside of drains. Along with this, other pests such as fruit flies and centipedes can also be attracted to drains.

So what can you do about these pest issues?

First of all, you need to keep your drains unblocked. This is important because pests need standing water to breed and survive. Something else you should do is routinely clean your drains. Remember, large amounts of food particles go down certain pipes such as from your kitchen. This is what attracts pests like drain flies and London cockroaches. Also seal up any drain pipes that are leaking because this will also cause pest issues.

The best way to clean your drains naturally, is by mixing a solution of vinegar, baking soda and hot water. Pouring this solution down the drain will help to wash away food particles and also kill bacteria. Another simple way to do this is by pouring boiling water from the kettle down your drain.

To protect your property from rats, you can install rodent blockers like rat flaps. These are basically stainless steel or plastic flaps that are placed inside drains at exit points. These flaps work in such a way that they open so that water can get out, but close up so rats cannot get in. These blockers are highly effective, and should be considered if you have rats in your drains.
