Constantia means big plots, old oaks, vineyards and horses, so pest control here is often as much about the garden and outbuildings as the house itself. Squirrels in the roof, rats around the stables and wasps in the hedges are everyday conversations in the valley.
Crawling insects around Constantia
Argentine ants trail in from the big gardens, and fishmoths like old wooden cupboards and boxes stored in outbuildings. Near the mountain edge, scorpions and rain spiders turn up in garages and pool rooms.
Many homes are large, older properties on generous stands, some Cape Dutch in style with thatched roofs, others modern with big glass walls and pool decks. Staff cottages, garages, stables and pool houses all add extra buildings that need checking. Thatch and exposed beams give rodents and borer beetles places that are hard to reach once they're established. The newer security estates have neater gardens but still back straight onto greenbelts.
Rodents lead the list, helped by horse feed, chicken coops, compost and all those outbuildings. Grey squirrels getting into roof spaces is a very Constantia problem. Paper wasps under eaves and in clipped hedges are a summer staple, and older thatch and timber bring borer questions whenever a house changes hands.
Something most people miss
People are often surprised that the cleanest kitchens can have German cockroaches. They usually arrive in cardboard boxes, second-hand appliances or grocery deliveries, and a warm motor compartment behind a fridge is all they need.
How to tell you have a problem
- Crickets chirp loudly from inside the house at night but go quiet when you get close.
- 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.
- Brown oval egg cases are tucked into hinges, under drawers or behind the stove.
- Fishmoths drop out of books, boxes or linen cupboards when you move them.
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.

Stopping a repeat visit
- Do not leave dishes in the sink overnight, since a wet sink is a feeding station for cockroaches.
- 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.
Pricing, honestly
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.
Shop-bought ant baits can handle a small, new trail and are worth a try. For cockroaches, especially German cockroaches, DIY sprays usually make things worse by scattering them and killing only the adults while the egg cases hatch. In flats and food businesses, I would not bother with DIY at all.
Crawling Insect Control questions from Constantia
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.
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.
Is the treatment safe around food?
We use gel baits and targeted applications in cracks rather than spraying food areas. Food should be covered or put away during treatment, and we will explain what to wipe down afterwards.
Does a thatched roof in Constantia need special treatment for borer?
The grass itself is not what borers are after, but the poles and battens holding it up can be. We inspect the visible timber for fresh holes and dust and treat only if there is active infestation.
Can you stop squirrels getting into my roof in Constantia?
Yes, but the lasting fix is physical. We find where they are getting in, usually a fascia gap or loose ridge tile next to an oak branch, and advise on sealing it once the roof is empty; cutting branches back from the roof helps a lot.
Do you come out to Constantia for crawling insect control?
Yes. Constantia is part of our regular Southern Suburbs route, along with Bergvliet, Tokai, Plumstead, Diep River. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
