Living on the Swartkops River in Redhouse means water, reeds and riverbank right on your doorstep. Most of the pests we treat here come from that: mosquitoes that breed in still water, Norway rats that live along the bank, spiders drawn to lights over the water, and fishmoths that thrive in damp rooms. You can't change the river, but you can make your house much less inviting.
The river shapes the pest picture
Redhouse is a riverside village, and many homes have gardens that run towards the water, boathouses, slipways, jetties and storerooms for fishing gear. Those spaces are quiet, damp and often closed up for weeks at a time, which is exactly what several pests look for. The air near the river stays humid, and in our mild climate that keeps insects active for most of the year.
The other thing about a riverside village is that the house is only part of the property. A rat problem might start under the slipway, a spider problem in the boathouse and a fishmoth problem in a storeroom full of old life jackets and magazines. So when we visit, we look at everything between the front gate and the water, not just the rooms you live in.
Mosquitoes and other biters
Mosquitoes need still water to breed, and they don't need much: a blocked gutter, a pot plant saucer, a boat cover holding rainwater or a forgotten bucket is enough. Reed beds and quiet edges of the river add to it. Summer evenings on the stoep are when you'll notice them.
There's no way to treat a river, so the work happens around your home: finding and removing breeding spots on your property, treating the resting places where adult mosquitoes shelter in dense plants and shady corners, and checking window screens. Our biting insect control in Port Elizabeth covers mosquitoes, fleas and other insects that bite.
Rats along the riverbank
Norway rats are good swimmers and burrow happily into riverbanks, under slipways and beneath sheds. From there they forage in gardens, compost heaps, bins and anywhere fish bait or scraps are left out. Signs include burrows in soft soil, runways through grass, gnawed fishing gear and droppings in the boathouse or garage.
We place lockable bait stations along the routes rats use between the bank and the house, and look for gaps under doors and around pipes. Riverside rodent work is very similar to what we do for rat problems in Bluewater Bay nearby.
Spiders around lights and boathouses
Outside lights near water attract insects, and insects attract spiders. Webs build up quickly along eaves, railings and boathouse doors. Most are harmless, but button spiders like quiet, undisturbed corners in sheds and under furniture, so it's worth taking care when clearing out stored gear. A targeted treatment of outside walls, eaves and outbuildings brings numbers down. See our spider treatments for homes and outbuildings.
Fishmoths in damp rooms
Riverside humidity suits fishmoths. They eat paper, book bindings, wallpaper paste and starchy fabrics, and they hide in cupboards, bookshelves and storerooms. If you're finding small silver insects when you move boxes or open a seldom-used cupboard, that's them. Treating the cracks and voids where they live, and reducing damp, clears them. More on our fishmoth control page.
How a visit goes
- We walk the house, garden, boathouse and outbuildings with you.
- We find the breeding spots, burrows and entry points rather than just treating what's visible.
- We treat what's needed, with care around the river: no loose poison, and sprays applied only where they're needed.
- We leave you with a short list of changes, from clearing a gutter to raising stored gear off the floor.
What people often get wrong
Fogging the garden for mosquitoes and assuming the job's done. Fogging knocks down the adults flying that evening, but the next batch hatches from the same water in the gutter a few days later. Removing breeding water around the house matters more than any spray.
A riverside tip
Check boat covers, tarps and dinghies after rain. Pooled water in a sagging cover is one of the most common mosquito breeding spots we find at riverside homes, and it's easy to miss because it's out of sight.
What does it cost?
It depends on the size of the property, how many outbuildings there are and which pests we're treating. A house with fishmoths in a few cupboards is a small job; rats along the bank with a boathouse and storerooms takes longer and often needs a follow-up. We'll quote after we've seen the property.

Questions we get asked
Can you get rid of mosquitoes if I live on the river?
We can reduce them a lot around your home, but not remove them completely. Clearing breeding water on your property and treating where adults rest makes the biggest difference.
Is rat bait safe to use near the river?
Bait in lockable stations placed away from the water's edge keeps it contained. We never put loose poison down near the river.
Why do I get so many spiders on my riverside stoep?
Outside lights near water draw insects, and spiders follow the food. Switching to warm-coloured or motion-sensor lights helps.
Do fishmoths damage clothes?
They can. They feed on starchy fabrics, paper and book bindings, so stored linen, books and boxes are most at risk.
Do you treat boathouses and storerooms?
Yes. We treat outbuildings along with the house, since they're often where the problem starts.
