Diep River is a working suburb strung along Main Road and the Southern Line, with family homes behind the shopfronts. Our calls are a mix of household rats and cockroaches and commercial jobs for businesses along the road.
Diep River: what drives crawling insects here
German cockroaches in kitchens and food businesses, Argentine ants trailing in from gardens and fishmoths in old wardrobes are the usual crawling calls.
Most homes are older freestanding houses and semis, with blocks of flats and townhouse complexes tucked in between. Main Road carries shops, takeaways, workshops and small light-industrial units. Older houses with suspended timber floors and outside rooms give rodents hiding places, while the commercial strip brings cockroaches and flies. Rental flats change tenants often, which is when bed bugs and cockroaches tend to arrive.
The suburb sits on fairly flat ground between Constantia's green slopes and the lower-lying flats toward Zandvlei, with small canalised streams running through. Winter rain pushes rodents in from gardens and from the railway reserve. The South-Easter is gentler here than out on the open Flats, so gardens stay fairly sheltered.
Something most people miss
For families with small children, simple habits like shaking out shoes, checking towels and keeping bedding off the floor are just as important as any treatment.
A common belief is that the bigger the scorpion, the more dangerous it is. In South Africa, it is the shape that matters: chunky pincers and a thin tail usually means mild venom, while slim pincers and a thick tail is the warning sign.
Signs to look for
- A UV torch at night reveals scorpions glowing blue-green in the garden or along the walls.
- Burrows with a crescent-shaped opening appear under rocks, at the base of walls or in sandy soil.
- Scorpions are found in pool filters, sumps or under pot plants after rain.
- They turn up in shoes, towels or laundry left on the floor.
- Scorpions appear inside after building work, landscaping or clearing rubble nearby.
- Scorpions are seen on walls, patios or in the garage at night.
Most scorpion stings in the Western Cape cause local pain and swelling similar to a bee sting. Stings from thick-tailed Parabuthus species can be much more serious, especially for small children, the elderly and people with medical conditions, and need prompt medical attention. Pets, particularly curious dogs and cats, can also be stung. If someone is stung by a thick-tailed scorpion or shows symptoms such as muscle weakness, trouble swallowing or difficulty breathing, get medical help straight away.
Our process, step by step
Scorpions are harder to kill with contact sprays than most insects, so we focus on a combination of habitat reduction and targeted treatment. We apply a residual treatment to entry points, door thresholds, wall bases, airbricks and known hiding spots around the outside of the house. Because scorpions follow their food, we also treat for crickets, cockroaches and other insects that attract them. Where burrows are found, they can be treated directly. We pair this with practical advice on clearing debris and sealing gaps, which is often what makes the biggest difference.

Keeping them out afterwards
- Use yellow or warm-coloured outside lights to attract fewer insects, which means fewer scorpions hunting them.
- Wear gloves when gardening, moving stones or clearing debris.
- Fit brush strips under doors and seal gaps around pipes, airbricks and window frames.
- Shake out shoes, boots and towels before using them, especially those left outside or on the floor.
- Move rubble, firewood, bricks and loose stones away from the walls of the house.
Pricing, honestly
The cost depends on the size of the property and garden, how much hiding space there is in rockeries and walls, and whether an insect treatment is needed to reduce their food. Properties on the edge of open veld or fynbos tend to have more ongoing pressure and may benefit from regular treatments. Follow-ups and any contract options are included in a free quote.
Scorpions are most active in the warm months from late spring to early autumn, especially on hot, still nights. The first rains of the season can flood burrows and drive them indoors or into garages. In winter they become much less active and stay in their burrows.
Questions we get asked in Diep River
Is the treatment safe for children and pets?
Products are applied outside around entry points and wall bases rather than in living areas. Keep children and pets off treated areas until dry, and we will advise you on the day.
Do you come out to Diep River for scorpion control?
Yes. Diep River is part of our regular Southern Suburbs route, along with Plumstead, Heathfield, Bergvliet, Retreat. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Can you treat my Main Road shop in Diep River after hours?
Yes. After-hours and weekend visits are available on request, so the treatment doesn't interrupt trading.
Can you get rid of scorpions completely?
Not entirely, especially next to veld or fynbos, because they move in from surrounding land. We can greatly reduce how many come close to and into the house.
Are the rats in Diep River coming from the railway line?
Often, yes. The railway reserve gives them cover to travel, so homes that back onto it see more activity and benefit from bait stations along that boundary.
Why do scorpions come indoors?
They come in hunting insects or looking for shelter, often after rain floods their burrows or on hot nights. Gaps under doors and around pipes make it easy for them.
