Wasp Control in Observatory

Obs is a neighbourhood of narrow streets, terraced cottages and a Lower Main Road lined with restaurants and bars.

Wasp nests in Observatory

Paper wasps nest under the eaves of Observatory's terraced cottages, in lean-to roofs added at the back, in backyard sheds and in the narrow lanes behind the rows. Because the cottages are so close together, a nest under one roof can affect the neighbours' doors and windows too. They're most active from late spring to late summer.

We treat and remove nests and check neighbouring eaves and lean-to roofs for others. Calling early in spring, while a nest is small, is quicker and safer, and we can talk to neighbours about nests that sit on a shared roof line.

Rows of little Victorian cottages share walls, roof spaces and sometimes back lanes, so pests move from house to house without ever going outside. Plenty have been split into digs for students and hospital staff. Restaurants and bars on Lower Main Road have cellars, back kitchens and bins in tight yards. Old suspended floors, cracked air bricks and lean-to kitchens added later are typical weak spots.

A note from the field

The first thing a technician looks for is old nests. A row of empty combs from last year tells us the property is a favourite and needs an early spring check.

Signs to look for

How we handle wasp control in Observatory

For ongoing wasp control we combine nest treatment with prevention rather than coming out once a year to remove whatever has grown. Active nests are treated with an insecticidal dust or spray applied directly into the comb, usually early in the morning or late in the day when the wasps are on the nest, and the comb is taken down once the colony is dead. On properties with repeat problems we do a sweep in early spring to find and remove young founding nests while they are small, and we can apply a residual treatment to favourite nesting spots such as eaves and pergolas. We also look at what is drawing wasps in, like water points, fallen fruit and open bins, and give practical advice on fixing it. For farms, estates and complexes, scheduled visits through the wasp season keep numbers under control instead of letting them build up.

Stopping a repeat visit

• Keep outdoor bins closed and clean up after a braai, as wasps scavenge meat and sweet drinks.
• Check garden furniture, umbrellas and the inside of letterboxes before using them in summer.
• Seal holes in hollow gate posts, steel poles and roller door channels with a cap or sealant.
• Walk around the house once a week from September and knock down any nest smaller than a coin with a long pole, at dusk, wearing long sleeves.
• Pick up fallen fruit and grapes promptly, because ripe fruit draws foraging wasps in late summer.

What affects the price

Wasp control is priced on how many nests there are, how high and hard to reach they are, and whether you want a once-off treatment or ongoing visits through the season. A house with one or two nests at ladder height is a straightforward job, while farms, estates and complexes with nests spread over many buildings take longer. For properties that get wasps every year, a seasonal plan usually saves money compared to repeated call-outs, and the quote is free.

Knocking down a tiny new nest in spring is a reasonable DIY job if you are not allergic and you do it at dusk. Once a nest is bigger than your palm, or it is high up, inside a wall or near where children play, we would rather you left it to us, because most of the stings we hear about come from people tackling a big nest with a can of spray in daylight. And if wasps keep coming back every year, the problem is the property and the neighbourhood, not one nest.
