Bugs That Love Rooftop Living

rooftops full of bugs

Roof spaces such as attics are great for storing belongings that you only want to look at once a decade, and patios can be a charming place to host a get together with your family or friends, but the shady nooks and crevices can also be appealing to pests such as rats, bees and wasps!
In particular, as we may not access our roof spaces regularly, we may not be aware of the pests inhabiting the space until the space becomes infested.
It is important to book inspections with a pest control company, such as The Pest Guys, before they become infestations, but if you do suspect that you have uninvited houseguests, don’t delay in contacting our professional team to have the problem treated!


Rodents are a suburban pest that have adapted to live alongside humans; they thrive in established suburbs where they have access to food and water from pet food, fruit and vegetable plants, scraps in rubbish bins and wood from palm trees, firewood and even wood within the structure of your home.

These pests are well known for their ability to spread disease. Rats can transmit disease through contaminating your food with urine or faeces, spreading bacteria with their urine or faeces, or spreading bacteria to your pets. To read more about how rats and other pests can spread disease, check out our “Pests That Spread Disease” blog.

Signs of an Infestation

Other than physically seeing a rat in your home, there are some other tell-tale signs to keep an eye out for:

  • Droppings around food packaging, cupboards, sinks, skirting boards or appliances;
  • Squeaking, gnawing or sounds of movement from within walls, cupboards, ceilings and under floorboards;
  • Chew marks or bite packages on food packaging;
  • Burrow holes around buildings;
  • Holes in walls and floors, likely creating an entry and exit point from your home;
  • Pieces of nesting materials around the kitchen, e.g. paper or fabric; and
  • Signs of fruit or vegetables being gnawed at or taken from your garden.

Preventing Rat Problems

There are several common sense ways to discourage rats from moving into your home, such as:

  • Removing any accessible food sources, such as ripe or rotten fruit;
  • Keeping rubbish and compost bins in good shape and ensuring rubbish bins are cleaned regularly;
  • Keeping your backyard clean and free of debris, such as garden waste and rubbish from sheds;
  • Cutting back plants and trees to remove the easy access route to your gutters and roof;
  • Cleaning pet dishes regularly and keeping pet food in a sealed container; and
  • Storing any food correctly in sealed containers.

Bees and Wasps

The beautiful warmth and sunshine of a West Australian spring and summer isn’t just enjoyed by us, our stinging insect friends are out to enjoy the weather too. While bees and wasps form an important part of our ecosystem, they can cause problems for homeowners, individuals and pets if they become agitated or threatened!

While bees can only sting once before they die, wasps can sting multiple times. These stings can cause an allergic reaction in some people. Pets can also suffer allergic reactions, and may be stung by a bee or wasps if they become a little too curious or playful.

Bees and wasps have some other distinct differences


  • Have a shorter body than wasps, with yellow abdominal bands
  • Swarm mainly in spring, but can be found into summer and autumn;
  • Nests are built in locations with easy access to the outside, such as roof spaces, sheds, wall cavities and tree branches;
  • Bees will usually only sting in defence.


There are two main types in WA: European Wasps and Paper Wasps. European wasps are:

  • Similar in size to a bee, with a black abdomen and bright yellow banding;
  • Generally not seen, as nests are commonly built underground, but can be built in ceilings, wall cavities and trees;
  • Aggressive in nature, and can sting multiple times if threatened or disturbed.

Paper wasps:

  • Have a more slender, longer body (15-25mm) with a slightly more yellow colouring than the European wasp.
  • Seen commonly hanging under eaves, pergolas or corrugated fence tops;
  • Nests are built in the open under eaves, corrugated fence tops and tree branches;
  • Generally not aggressive unless their nest is disturbed or they are threatened.

Removing Bees and Wasps

If you notice a distinct buzz around your house or outdoor roof spaces, it is time to call in the professionals! Unlike rats, that may cause structural damage as well as harm, bees and wasps are a nuisance due to their stings, with different people reacting differently to stings from these pests.

If bees are a problem, The Pest Guys will first recommend that you get in touch with an apiarist, who will remove or control the beehive where it presents a minimal risk to humans. However, the only way to control a wasp nest is to have it destroyed by a licensed pest controller, such as our team at The Pest Guys.

The Pest Guys employ non-toxic treatment methods to ensure you and your family remain safe both during and after the treatment.

With the warm summer weather luring more of us outdoors where we may encounter the pests that have nested at our homes, it is important to be proactive in having your house inspected or treated for infestations. This will not only give you and your family peace of mind, it will keep your family and pets safe at home throughout the upcoming summer holidays.
