St James is a narrow strip of grand old houses squeezed between the mountain and False Bay, best known for its colourful bathing boxes and tidal pool. With the mountain right behind and the sea in front, homes deal with damp, wind and wildlife all year.
St James: what drives crawling insects here
Fishmoths love damp cupboards and libraries in old houses, and spiders shelter in rockeries and walls. Ants trail in during dry weather.
Many homes are large Edwardian and Victorian houses on steep plots, with timber floors, wooden verandas and big roof spaces. There are also flats and newer homes higher up the slope. Steep sites, terraced gardens and stone retaining walls give rodents and spiders lots of hiding places. Old timber and damp sea air create ideal conditions for fishmoths and wood borer.
Rats and mice from the mountain slopes are the biggest problem, with fishmoths and wood borer close behind. Ants and spiders are common in summer, and gulls and pigeons are regular around the coast.
Worth knowing
In blocks of flats, body corporates get far better value from a scheduled treatment of all units and shared drains than from individual owners treating one flat at a time.
One of the most common mistakes is spraying insecticide over ant bait. It contaminates the bait and the ants stop feeding on it, so the colony survives.
Signs to look for
- Fishmoths drop out of books, boxes or linen cupboards when you move them.
- There is a faint musty, oily smell in a cupboard that has not been opened for a while.
- Dead insects collect on window sills, in light fittings or along the bottom of the garage door.
- Ant trails run from a crack in the floor or wall to the dog bowl, sugar bowl or dishwasher.
Our process, step by step
Crawling insects walk through treated areas and carry baits back to their nests, which is exactly why baits and dusts work so well on them. We use gel baits in cracks and hinges for cockroaches and slow-acting ant baits that the workers take home to the queen. Insect growth regulators stop young cockroaches from maturing and breeding, which matters for German cockroaches that multiply fast. Residual sprays are applied as a barrier along entry points, door thresholds and drain areas rather than across open floors. Dusts go into wall voids, ceiling spaces and plug points where liquids should not be used.

Keeping them out afterwards
- Store books and documents in sealed plastic boxes in dry rooms rather than in damp garages.
- Seal gaps under exterior doors with a brush strip, because most crawling insects simply walk in.
- Move firewood, compost and piles of bricks away from the house walls.
- Put drain covers or mesh over floor drains and keep the water traps full, especially in guest bathrooms that are seldom used.
- Check second-hand furniture, appliances and cardboard boxes before bringing them inside, as German cockroaches often move house this way.
How much will it cost?
Cost is driven by the species and how established the infestation is, with German cockroaches in a busy kitchen usually needing more work than a one-off ant trail. The size of the property, the number of units or rooms affected, and access to roof spaces and drains also matter. Where a follow-up treatment is needed to catch hatching insects, or where a business wants a regular service contract, we build that into a free quote upfront.
The first heavy rains in late autumn and winter push ants, cockroaches, crickets and millipedes indoors in large numbers. Summer heat brings American cockroaches out of drains and sends ants foraging hard for water. German cockroaches and fishmoths do not care much about the season because they live inside heated buildings all year.
Frequently asked questions
Do you come out to St James for crawling insect control?
Yes. St James is part of our regular South Peninsula route, along with Muizenberg, Kalk Bay, Lakeside. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Can crawling insects come from my neighbour?
Yes, particularly in flats, townhouses and semi-detached homes that share walls, drains and roof spaces. Treating several units together gives much better results.
Will one treatment get rid of cockroaches?
For American cockroaches it often will. German cockroaches usually need a follow-up because their egg cases are protected and hatch after the first treatment.
Why do I have so many fishmoths in my St James house?
Sea air and mountain damp keep old houses humid, and fishmoths love that. Drying out cupboards and a targeted treatment brings numbers down.
What counts as a crawling insect?
Anything that mainly walks rather than flies: cockroaches, ants, fishmoths, crickets, earwigs, millipedes and scorpions. They hide in cracks and voids, which is why they are treated with baits, dusts and barriers.
Can you inspect my old St James home for wood borer before I sell?
Yes, we inspect floors, roof timbers and verandas and give you a written report. Many sales need a beetle certificate, so book early.
