How to control wasp nests?

Wacky Wasps

As the warm weather approaches and we spend more time enjoying the outdoors we begin to notice an increased presence of wasps. Wasps are active from spring when the hibernating Queens lay eggs to create the first few female workers. In early summer, these workers are busy collecting insects to feed the larvae in the nest so tend not to bother us very much.
However, they do get addicted to a sweet secretion that is exuded by the growing larvae and by late summer when all the grubs have grown up, the adult wasps turn their attention to sweet things on our table. This is when we notice them and when they become wacky and a nuisance to us. Find out below how to control wasp nests.

Signs of wasp nests

If you do begin to experience a high number of wasps in your home or garden there will most likely be a nest nearby. Treating a wasp nest early is key to reducing the threat and stopping further nests. Wasps make their nests from chewed wood pulp and saliva which gives them papery walls. These nests are usually found and built in sheltered spots. These often include places such as wall cavities, roof spaces, sheds, gardens etc. You can locate a nest by watching the flight path of returning wasps. Wasp nests initially start off very small. However over time they grow rapidly in size as the number of wasps increases.

How to identify a wasp nest

Wasp nests and bee hives are commonly confused which can lead to unsuccessful results as treatment available for each differs. Bees are an endangered species and a bee nest should only be removed if it poses a significant threat. Treatment for a wasp nest is more common and with our products can be carried out very efficiently on a DIY basis.  The main way to identify a wasp from a bee nest is by looking at the material used to construct the nest. Wasps build nests with a ‘paperlike’ substance from chewed wood fibre and saliva whereas bees use beeswax, a waxy substance they secrete from their abdomens to create their detailed nests.

How to control wasp nests

  • Step 1: Arm yourself with a spray tin of Keen Flying Insect Killer to kill any wasps that are flying around, plus a tin of SX Pro Wasp Killer Foam or Digrain Wasp/Hornet Nest Destroyer. If the nest is in the loft, you could set off a smoke bomb as an alternative to ridding the area of any flying wasps before treating the nest.  If you have access to the nest entrance, you might prefer to treat it with a powder formulation. Residex P or Ficam D are both very effective treatments for wasp nests but you will need an applicator such as a Pest Pistol Insect Duster, Polminor or a Dustick Duster.
  • Step 2: Ensure you wear protective clothing including a gloves and a veil. Approach slowly and carefully at a time when there is the least amount of activity around the nest. This is likely to be dusk or early morning.
  • Step 3: If it is dark and you have to use a torch, don’t shine the torch directly on the nest and ensure you have planned your access and escape route in advance don’t hold the torch next to your body.
  • Step 4: Briefly test your sprays before attempting the job so you know the range of the spray. Usually an effective distance is about three metres.
  • Step 5: Get yourself quietly into position and spray around the nest with the Keen Flying Insect Killer to get rid of any wasps crawling over the outside of the nest on guard duty. Then take up your chosen product and thoroughly spray the entire nest all over. Alternatively, puff your powder product inside the nest and around the entrance. This will ensure that any wasps coming back to the nest after treatment carry the product into the nest with them.
  • Step 6: Leave the area and wait to see if your treatment has been successful. If not apply another dose.
