Cockroaches are always looking for sources for food, so it doesn’t take much to draw them in. Because of this, you need to store any leftovers quickly and ensure you don’t leave any food out in the open. Any food in your pantry or cupboard should be in airtight, secure containers.
This might be harsh, but the fact is that cockroaches don’t usually like clean, pristine homes. If you’re not sweeping, mopping, wiping down counters and tables and taking out the trash every night, then you’re leaving food particles behind. Cockroaches are happy to clean them up for you. Roaches can also fit underneath doors and window sills that aren’t tightly sealed. Make sure there’s no space underneath doors that lead outside, and check window sills carefully. You should also check window screens for holes.
If you’re new in this house, there’s a possibility the cockroaches were already lurking somewhere unseen, such as the garage. If the cockroach infestation was small, there may not have been any warning signs before you moved in – and now the infestation has grown, which is why you’re seeing roaches.
It only takes a tiny hole or crack for cockroaches to squeeze into your home. Take a close look at every wall and the foundation closely for possible openings. Seal up any holes or cracks you find with caulking. If you find holes or cracks in your foundation, you’ll probably require a more heavy duty patching, but it should also be dealt with properly.
Calling in your pest professional right away will help you get a better idea of the main reason why you have a cockroach issue. Make sure you take note of all their suggestions, and implement them going forward so that you never have to deal with this issue again.
